Definitions
- the invention relates to the field of fluidic components, applied in particular to biological analysis devices.
- the invention can in particular be applied to fluidic components having, on the one hand, deep structuring (reservoir and / or capillary and / or closure of the component) and, on the other hand, electrode structuring.
- APS components made in CMOS technology are known from, for example, F. Mallard et al., Published in "Biosensors and Bioelectronics," Vol. 20, 2005, p. 1813-1820.
- An APS chip has an active area, itself having a matrix of pixels, surrounded in whole or in part, a zone of microelectronic electronic processing circuits. The latter is surrounded by the area of electrical contacts. These contacts are located at the periphery of the component (on 1, or 2, or 3 or 4 sides).
- a pixel consists of an active zone (photodetector) and an electronic signal preprocessing function zone.
- the detection surface (sum of all the surfaces of the photodetectors) of the detection matrix therefore has a filling rate of much less than 100%.
- FIG. 1 shows a sectional view of the technological stack concerned. This figure represents the structure of a single detector, not a matrix of detectors.
- This figure shows the central zone 2, at the periphery of which the contacts 4 consist of metal studs covered with a passivation layer (oxide) 5.
- the extruded parts of these studs not shown in the figure, allow the resumption of electrical contacts.
- Intermediate zone 6 normally consists of electronic signal processing functions coming from the central detection zone 2.
- the chip is glued on a support memory film 12, of the PCB type, comprising two metal levels: one on each face and a level 14 of via allowing contacting of the two faces.
- a contact connection 16 with the memory film 12 is performed to resume the electrical contacts of the chip.
- a passivation resin 18 is deposited and crosslinked over the whole of this connection to protect the entire electrical part of the component (contacts on the chip, connection wires and electrical side of the memory film).
- the memory film carrying the chip is assembled with a cover 20, comprising fluidic structures to form a fluid cavity, carried on the component.
- the resin covers all the metal surfaces, while having a minimum distribution on the surface of the chip, otherwise encroach on the active area.
- 500 ⁇ m is to be expected between the contacts and the active area of the chip. This represents an important lost place on the chip.
- the thickness of the resin 18 above the surface of the chip-memory film assembly 12 is a parameter that is not very reproducible. This adds an additional constraint to the depth of the fluidics of the component. This constraint considerably limits any work on the reduction of the volume of the fluidic cavity.
- the implementation of a bonnet carryover implies the existence of a transfer zone 13 between this cover and the support of the detection chip, a transfer zone that must be sealed, resulting in an enlargement additional room.
- the non-reproducible nature of the form of the passivation following the creep of the resin 18 does not allow good control of the fluid flows in the component, and for example imposes dead zones in the corners of the components.
- the volume of the fluidic part defined in fact by the depth p structured in the cover 20, is difficult to reproduce.
- this assembly architecture imposes, in the biological reaction chamber, the presence of a resin or a polymer whose nature must be taken into account in the development of biological protocols. Functionalization (for example by biological probes) before assembly is also problematic. The presence of metals (such as electrical contact recovery pads) on the surface of the chip renders unusable any biological functionalization protocol that uses oxidation or reduction steps, with bases and acids.
- the fluidic part of the component is produced on a 350 ⁇ m thick substrate and a depth of 72 ⁇ m ⁇ 4 ⁇ m (for 60 minutes of etching). There remains a thickness of silicon, of the order of 278 microns, under the fluidic part.
- the realized detector collects the electron-hole pairs created by the absorption of the photons coming from the fluidic part of the component. Given the absorption of silicon, these pairs are created in a layer of the order of 10 microns thick, under the fluidic part. These pairs are collected by the junctions made on the back of the component. They must therefore travel a thick silicon (262 microns) before being collected by the junctions.
- Figure 4 of this document shows a chip of 1 x 2 cm 2 , with 9 times of electrical contact, which represents at best 4 detectors on the chip.
- the photodetector technology used in this document is therefore atypical and allows only one component that provides a number of constraints.
- the last step of producing an APS chip (and CMOS in general), before chip cutting usually consists in performing a step of thinning substrates to facilitate the packaging steps.
- the substrates are thinned to a thickness of, for example, between 700 ⁇ m and 100 ⁇ m. It also seeks a structure, and a method for achieving it, in which the problems posed by the implementation of a transfer technique, in particular the alignment of the fluidic vis-à-vis the active surface, do not do not arise.

- the component according to the invention further comprises a cover which closes the fluidic part.
- This cover is preferably placed in a sealed manner.
- the seal can be obtained by depositing an epoxy adhesive by screen printing, prior to assembly of the fluid component and the cover. Such an assembly method is described in patent application WO-A-2004/112961, in the names of the applicants.
- the assembly of the cover and the fluid component, facing the fluidic part is reversible.
- the cover comprises fluidic communication means allowing a fluidic exchange between the fluidic part and any external fluidic element.
- fluidic communication means may be, for example, through holes surmounted by a connector base, for connecting the fluid component to a pump or a pressure tank.

- the barrier layer forms a stop layer of the etching on the rear face to define the depth of the fluidic part of the component in the support.
- the latter is for example silicon or, more generally, semiconductor material.
- the detection means may comprise at least one photodetector.
- a device according to the invention may further comprise a passivation and / or stiffening layer.
- This layer is made for example of silicon oxide directly on the detection / activation means or on the surface layer.
- Means for detecting electrical properties of a fluid can be made, for example at least in part in the etch stop layer.
- Part of these means is in contact with the fluidic part.
- means for activating a fluid by electrowetting may also be carried out, possibly with electronic means for controlling the means for activating a fluid by electrowetting.
- Fluid reservoirs may also be made in the substrate.
- the barrier layer, and optionally the surface layer formed on the barrier layer have a thickness less than 10 microns.
- the fluidic part which makes it possible to receive a fluid, can have a well-controlled depth, for example less than 300 ⁇ m or 100 ⁇ m.

- the invention also makes it possible to produce a matrix of high density detectors comprising a plurality of components as described above, separated from each other by a distance less than
- the technology for producing the fluidic part is therefore adapted to a microelectronic technology, for example of the CMOS type.
- Deep etching of the semiconductor material of the support is carried out, so that an emission of photons from the fluid can reach the detection means made on the other side of the component.
- a chip or a component according to the invention may comprise a stiffening substrate.

- the inlet vias in the fluidic part are not made through the support of the substrate used. Therefore, no useful area is lost on the detection part of the component. This also makes it possible to perform chemical steps - in collective manufacturing - aggressive on the fluidic part, without giving access to the other side of the substrate (to avoid damage to the detection means located on the other side).
- the invention makes it possible to take advantage of the use of an SOI substrate and the associated CMOS technology. It also makes it possible to have an advantageous embodiment of the fluidic part.

- FIG. 3B shows an SOI substrate 30, which typically comprises a support 32 made of semiconductor material, a layer 34 of dielectric material, and a surface layer 36 of semiconductor material
- the layer 72 or the layer 34 will serve as a stop layer during a step of etching the fluidic part in the substrate 70 or in the support 32.
- the fluidic portion can be easily made, its depth d being determined solely by the thickness of the part of the substrate or the support located under the barrier layer, minus any partial thinning of the substrate.
- the layer 72 (or all of the two layers 34 and 36) has a thickness e of a few ⁇ m, for example between 1 ⁇ m and 10 ⁇ m, while the substrate 70 or the support 32 has a thickness less than a few hundreds of ⁇ m, for example less than 500 ⁇ m or between 10 ⁇ m and 50 ⁇ m or 90 ⁇ m or between 10 ⁇ m and 300 ⁇ m.
- the present invention makes it possible to avoid the transfer techniques with alignment of the fluidic part on the detection or activation part, as explained below in the various examples.
- FIG. 4A shows, in the case of a CMOS chip, how this can be performed on an SOI substrate in the context of a device according to the present invention.
- a detector 38 here based on a component derived from CMOS technology, is formed in or on the SOI substrate semiconductor surface layer 36 on a first side of the barrier layer. Electrodes 37, 39 make it possible to ensure contacts with the detector. The assembly is disposed on the front face 41 of the SOI substrate.

- the invention does not require passivation of contact recovery electrodes 37, 39, since these are located on the face 41 of the substrate (on the side of the stop layer dedicated to the detection), opposite the face 43 from which the fluidic portion or chamber 40 (on the other side of the barrier layer) is made.
- no fluid communication is established between these two faces 41, 43 or between the chamber 40 and the detection part.
- the study of the interface zone 33 between the fluidic part and the barrier layer can easily show that there has been no transfer, but that one and the same substrate has been used for both parts.

- Metal electrodes 50 which will be opposite the portion or the fluid chamber 40 in the final component, are then formed .

"Electrowetting based actuation of droplets for integrated microfluidics", Lab Chip, 2002, 2, 96-101, can also be used in the production of a device according to the invention. It implements a fluidic structuring around the areas of metal electrodes electrowetting. In combination with such a fluid displacement component by electrowetting, one can also make reagent distribution tanks or define a closed volume of the active part of the component, or define a volume of oil.
- the invention can, again, be used to provide a simplification of the packaging and use of such components.
- a semiconductor substrate 70 may be used as a starting board, such as that illustrated in FIG. Figure 3A, in place of an SOI substrate ( Figure 7).
- It may be a silicon substrate 70, oxidized to obtain a desired thickness of dielectric layer 72 to provide the isolation function of the electrowetting device.
- the metal electrodes 74 are then formed on the surface of this oxide 72 without it being necessary to passivate the front face 79.
- the fluidic part or the fluidic structuring can then be carried out, as in the other embodiments, by the face back of the substrate, using silicon oxide 72 as a barrier layer.
- a deposit of hydrophobic material 80 may be made on the rear face, in order to promote the effect of electrowetting.
- FIG. 7 shows in section a simplified technology of a chip with fluid displacement by electrowetting, with structuring fluidic back.
- the method of etching the fluidic part of the component can be simplified because it does not participate in the definition of the reaction volume: the latter is defined by the number of electrowetting electrodes activated.
- the fluidic part may comprise several reservoirs: there are three, referenced 71, 73, 75 in Figure 7. Some tanks may be assigned specific functions: for example, the reservoir 75 may be a reaction zone and displacement of drops, these drops can be brought adjacent tanks 71, 73.
- a layer 77 of passivation and stiffening oxide may be formed on the front face of the substrate.
- FIG. 4A again a semiconductor-on-insulator structure with its three levels 32, 34, 36, as in FIGS. 4A and 4B, and electrowiring electrodes 74 made on the front face of an insulating layer 34 covered with a hydrophobic layer 80 on the back.
- Electronic components 60 for example of the CMOS type, are produced in the semiconductor layer 36.
- the other references designate elements that are identical or similar to those of FIG. 7.
- SOI semiconductor on insulator
- any type of detector and / or actuator for example MEMS technology derived from CMOS technology, can be incorporated.
- the fluidic part is carried out after the detection part, since it is preferable to carry out the part with a higher topology at the end. But it is also possible to proceed in reverse order.
- the invention notably makes it possible to produce a fluidic component comprising detection and / or activation means and means - said fluidic means - forming a fluidic part for receiving a fluid, characterized in that:
