Definitions
- the invention is based on a method for connecting a silicon plate to a further plate according to the preamble of the independent claim.
- Methods are already known in which a silicon plate is connected to a further plate by placing the silicon plate on the further plate. If the further plate is formed from a certain glass, a connection between the silicon plate 1 and the further plate 2 can be established by increasing the temperature and / or applying electrical voltages. This process is known to the person skilled in the art as anodic bonding.
- silicon plates can be bonded to other plates by adhesive processes.
- connection areas between a silicon plate and another plate can be formed.
- the space required for such a connection can therefore be particularly small being held.
- the method allows the selection of a large number of materials for the further plate, ie the silicon plate can be connected to a further plate which is selected from a large number of materials.
- the highly absorbent material can either be formed as a thin, superficial layer or the further plate consists entirely of this material.
- a variety of materials can be used for the highly absorbent material and a variety of materials for the further plate.
- the actual connection can be made by a variety of connection methods such as gluing, soldering, positive connection or welding.
- hermetically sealed connections can be created, in which a cavity is then hermetically closed by a circumferential seam. Contacting into the cavity can then be provided within the circumferential seam.
- the method according to the invention is particularly suitable if a multiplicity of structures are produced simultaneously on the silicon plate or the further plate. It is then advantageous to fix this adjustment by means of a point connection immediately after an adjustment of the two plates to one another.
- FIG. 1 and 2 show a first exemplary embodiment of the method according to the invention
- FIG. 3 shows a further exemplary embodiment of the method according to the invention
- FIGS. 4 and 5 show a further exemplary embodiment of the method according to the invention
- Figure 9 shows another embodiment of the method according to the invention, wherein all figures each represent a cross section through the plates.
- the 1 shows a silicon plate 1 which is arranged on a further plate 2.
- a laser beam 3 is directed through the silicon plate 1 onto the surface of the further plate 2.
- the wavelength of the laser beam 3 is selected such that only a negligibly small amount of energy is absorbed in the silicon material 1. This is achieved in that the wavelength of the laser light is in the infrared, since silicon is transparent in this frequency range.
- the material of the further plate 2 is selected so that strong absorption takes place in a thin, superficial layer. This strong absorption of the laser energy in a relatively thin layer results in a strong thermal heating of this layer, which leads to melting of this area.
- a connection to the silicon plate 1 can be established through the melted area. Various connection mechanisms are conceivable.
- the melted material of the further silicon plate 2 can be glued to the surface of the silicon wafer 1. This takes place, for example, when the further plate 2 is formed from a plastic material which is melted by the energy of the laser beam 3 introduced. Such a plastic plate 2 is then superficially bonded to the surface of the silicon wafer 1. Furthermore, welding can take place in such a way that both the further plate 2 and the silicon plate 1 are melted on account of the energy introduced by the laser beam. The energy absorbed in the further plate 2 is also transferred to the silicon wafer 1 by heat conduction. This then causes both the further plate 2 and the silicon wafer 1 to melt.
- the molten material of the silicon plate 1 and the further plate 2 thereby mix and form a mixed melt the material, both the silicon plate 1 and the further plate 2 contains. After cooling, this melting area then forms the weld connection between the silicon plate 1 and the further plate 2. Furthermore, a positive connection can also take place, which is explained further below with reference to FIGS. 3 and 4. Furthermore, there may also be a solder connection between the silicon plate 1 and the further plate 2.
- a connection of the silicon plate 1 to the further plate 2 through a hot-melt adhesive region 11 is shown in FIG.
- the use of a plastic material for the further plate 2 is particularly intended here.
- the plastic material of the further plate 2 is melted and has wetted the surface of the silicon wafer 1 in the liquid state. Adhesive forces then cause the silicon plate 1 to adhere to the further plate 2.
- FIG. 3 shows the configuration of the connection area as a welding area 12 as a further example. Starting from FIG. 1, the energy of the laser beam 3 causes both the further plate to melt
- the welding region 12 is formed by mixing the two materials in the molten state and solidifying during cooling.
- the further plate 2 in particular ceramic material, glass or semiconductor materials (in particular silicon) or metal are considered.
- the material of the further plate 2 is in turn designed so that there is a strong absorption of the energy of the laser beam
- connection area is formed as a positive-locking area 13 (FIG. 5) by the energy of the laser beam 3 introduced.
- the silicon plate 1 has a depression 14 and the further plate 2 has a pin 15.
- the deepening 14 placed on the pin 15 and there is a heating of the material of the pin 15 by the energy of the laser beam 3.
- the melting of the material of the pin 15 leads to a deformation of the pin, in particular the molten material of the pin 15 fills the cavity of the Well 14 completely.
- the recess 14 should in particular be designed in such a way that it has an undercut, ie that the recess 14 has a larger diameter in depth than on the surface with which the silicon plate 1 faces the further plate 2.
- Such undercuts can be formed in silicon plate 1 by using etching processes. It is thus possible to form a positive connection between a silicon plate 1 and a further plate 2.
- the further plate 2 consists entirely of one and the same material, which is highly absorbent for the wavelength of the laser beam 3.
- the highly absorbent layer is arranged between the silicon plate 1 and the further plate 2. It is also irrelevant whether the highly absorbent layer is arranged on the silicon plate 1 or the further plate 1 before the connection. Such a connection process is shown in FIGS. 6-8.
- FIG. 6 shows a silicon plate 1 and a further plate 2 in an expanded state.
- An absorption layer 20 and a recess 21 are provided on the side of the silicon plate 1 which faces the further plate 2.
- the silicon plate 1 with the absorption layer 20 is placed on the further plate 2, and a laser beam is then directed through the silicon plate 1 onto the absorption layer 20.
- the recess 21 is arranged over the micromechanical structure 22.
- the recess 21 is dimensioned such that a cavity 23 remains above the micromechanical structure 22. Energy is introduced into the absorption layer 20 by the laser beam 3 in such a way that this absorption layer is strongly heated.
- the absorption layer 20 can be used for various materials.
- a glass plate or a silicon plate can be used for the further plate 2, and the absorption layer 20 can be formed from plastic.
- Such a plastic layer would then result in an adhesive connection as has already been described for FIG. 2.
- the absorption layer 20 can also be provided with a pin 15 and the silicon plate 1 can also have depressions 14. It could then, similar to that already described in FIGS. 4 and 5, a connection by means of a Form-locking area 13 take place.
- An absorption layer 20 which is relatively thin in comparison to the plates 1 and 2 and which is equipped with corresponding pins 15 can also be used for this shape.
- the further plate 2 also consists of a silicon wafer.
- Thin metal layers for example made of aluminum, aluminum-silicon-copper, platinum, titanium, chromium or other refractory metals, can then be used for the absorbent layer.
- germanium, silicon germanium or highly doped polysilicon layers can be used for the absorption layer 20.
- Oxides and nitrides, for example silicon oxide and silicon nitride, can also be used as absorption layers as further materials for the absorption layer 20.
- the absorption layer can be used in relatively small layer thicknesses, however the layer thickness approximately corresponds to the penetration depth of the laser, i.e.
- typical layer thicknesses are on the order of more than 100 nanometers.
- the material for such layers can be made using the usual methods of thin-film technology such as sputtering, vapor deposition, spin coating, CVD deposition, epitaxy and the like. Furthermore, the
- Absorbent layers 20 are structured, ie they are only arranged where the welded joints 12 are to be made later. Insofar as it is simpler in terms of process technology and the layers do not fear any impairment of any micromechanical structures 22 provided, these layers can also be applied over the entire area. In addition to the connections already described by means of gluing, positive locking and welding, the connection through the absorption layer 20 can also be made by soldering.
- the absorption layer 20 is formed from a material which, in the melted state, produces a solder connection between the silicon plate 1 and the further plate 2. This can be particularly useful if the further plate 2 is a metal plate.
- FIGS. 6-8 describe that a micromechanical structure 22 is arranged in a cavity 23 which is formed by the recess 21.
- a micromechanical structure 22 is arranged in a cavity 23 which is formed by the recess 21.
- Such a process involves the packaging of a micromechanical component, in which the micromechanical component 22 is hermetically sealed in a cavity 23. It is then provided that the welded connection 12 is formed as a circumferential seam, ie that the welded connection 12 completely surrounds the micromechanical structure 22 in the plane formed by the two plates 1, 2. The problem then arises of how this micromechanical structure 22 is electrically contacted.
- FIG. 9, represents a cross section through an exemplary micromechanical structure.
- the silicon plate is arranged here as the bottom plate and, as shown by the arrows, the laser beams are irradiated from below.
- Welding areas 12 which completely surround the micromechanical structure 22 were formed here by the laser beams 3.
- the micromechanical structures 22 are also only shown schematically here.
- the micromechanical structures 22 are covered by a further cover plate 50, which is spaced from the micromechanical structures 22 by means of a spacer layer 51 forms.
- the micromechanical structures 22 were formed by introducing trenches into the further plate 2, which cut through the further plate 2 from top to bottom. Trench structures of this type can be introduced particularly easily into silicon plates, so that the further plate 2 is usually formed from silicon here.
- the micromechanical structures have a connection region 52 which is separated from the remaining material of the silicon plate 2 by a trench structure 53.
- this connection area 52 the material of the silicon plate 2 is directly connected to the material of the cover plate 50.
- a silicon plate is also considered for the cover plate 50, which is made conductive at least in some areas by doping.
- a contact area 54 on which a contact metallization 55 is applied, is formed above the connection area 52.
- the contact area 54 is in turn electrically insulated from the rest of the silicon plate 50 by trenches 53.
- An electrical contact to the micromechanical structures 22, which are arranged in the cavity 23, can be produced by the contact metallization 55 and the contact area 54 or connection area 52 lying underneath.
- the method according to the invention is preferably applied to silicon plates which have a large number of structures. Since silicon plates are transparent to infrared light, a silicon plate 1 can be used Alignment of the silicon plate 1 relative to the other plate 2 take place. The two plates can then be connected point by point by laser radiation, which effectively prevents the two plates from slipping relative to one another in the further processing. The actual connections can then be made, which can take longer, for example, in terms of the processing time, than the adjustment of the two plates 1, 2 relative to one another or the point-by-point connection. This is of particular interest if a large number of structures are formed in the silicon plate 1 or the further plate 2 and connections are to be produced over large areas.
