Although the present invention discloses the above method of removing the photoresist layer 428 to form the nozzle hole 432, the present invention is not limited thereto, and the present invention may also form the structural layer 430 first. A lithography etching step is performed to pattern the structural layer 43A to define the orifices 432. Subsequently, the plating initiation layer 426 in the orifice 432 is removed. Next, referring to FIG. 4D, a second image 403 of the substrate is patterned, such as a lithography process, or a sandblasting method to form a fluid channel 434, exposing the first sacrificial layer 424, and then passing through the fluid channel. 434, the first sacrificial layer 424 is removed by an etching method to form a fluid chamber 436 that communicates with the fluid channel 434. When the first sacrificial layer 424 is composed of a polymer, the first sacrificial layer 424 composed of a polymer may be removed by a plasma ashing method or a stripper. The present invention is not limited thereto, that is, the steps of forming the fluid passage 434 may be sequentially exchanged, for example, the first sacrificial layer 424 may be removed first through the injection hole 432, and then the fluid may be formed on the second surface 403 of the substrate 4 Channel 434. Next, referring to FIG. 4E, a second sacrificial layer 48 is formed on the structural layer 430. The composition and formation method of the second sacrificial layer 480 can be similar to the above embodiment, and is not described in detail herein. It should be noted that the second sacrificial layer 480 is not formed on the sidewall of the nozzle hole 432. Subsequently, referring to FIG. 4F, a plating initiation layer 482 is formed on the first sacrificial layer 480 and the sidewall of the nozzle hole 432 by a metal plating method, and the metal plating method may be a metal deposition process such as physical vapor deposition. The plating initiation layer 482 may be composed of Ti, TiW, Cr, Au, state, & or % Ta metal. Similarly, the composition and formation method of the sacrificial layer 480 may be similar to the above embodiment. Clean, not described in detail here. 0535-A21414TWF(N2);A05211 ;WAYNE ίο 1273984 Please refer to Figure 4G, who will remove the second sacrificial layer 480 and remove the second sacrificial layer 480. The plating initiation layer 482 on the sacrificial layer 480 retains only a portion of the plating initiation layer 482a on the sidewalls of the orifice 孔 and the hole 432. For example, in the case of a polymer 笫 膳 · 卜 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 牺牲 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二The process removes the second sacrificial layer and, in addition, the first sacrificial layer 480 of the electrical layer, the second sacrificial layer 480 can be removed using, for example, wet etching. Please refer to the 4th picture of the tea photo, with a "Lei Saigu, ι+Λ ^ ^ ^ encapsulation method on the pen plating initial layer 480a ^ - electroplating layer, because in the electric bell process of the electric clock, only Electrically, the surface of the starting layer 482a will react. Therefore, the electric clock layer will only form the plating starting layer 482a in the hole 432, wherein the electric bonding layer 484 and the plating starting layer 482a constitute an inner liner 4%. To reduce the size of the orifice 432. It should be noted that in the electroplating process, the electric clock layer in the nozzle hole is thickened with the increase of the plating time. Therefore, the size of the nozzle hole 432 is also reduced. The condition is proportional to the plating time, so the size of the orifice 432 can be controlled by controlling the plating time. According to the above embodiment, when the size of the nozzle hole needs to be changed, the size of the nozzle hole can be changed without using a different mask, and the manufacturing cost of the mask can be reduced, and the process is more flexible. While the present invention has been described in its preferred embodiments, the present invention is not intended to limit the invention, and it is intended that the invention may be modified and practiced without departing from the spirit and scope of the invention.
