Background

The solar cell is divided into a crystalline silicon type and an amorphous silicon type, wherein the crystalline silicon type cell can be divided into a single crystal cell and a polycrystalline cell; crystalline silicon with higher monocrystalline silicon efficiency also distinguishes that the solar cell needs to be etched in the processing process, and the etching is a quite important step in a semiconductor manufacturing process, a microelectronic IC manufacturing process and a micro-nano manufacturing process. Is one of the main processes of patterning processes associated with photolithography. Etching is actually understood in a narrow sense as photolithographic etching, in which the photoresist is first subjected to a photolithographic exposure process by photolithography and then etched away by other means to remove the portions to be removed. Etching is a process of selectively removing unwanted material from the surface of a silicon wafer by chemical or physical means, with the primary objective being to properly replicate the mask pattern on a gummed silicon wafer. With the development of micro-fabrication technology, etching is a general term for stripping and removing materials by solution, reactive ion or other mechanical means, which is a common name for micro-fabrication.
