Why are dry etching processes more promising than PVD and CVD processes?

The importance of deposition and etching in semiconductor manufacturing

Deposition and etching are respectively two processes of increase and decrease, both of which are equally important in semiconductor manufacturing and indispensable. Deposition is the formation of various functional material layers on the wafer, these materials can be conductors, semiconductors and insulators, etc., each of which plays its due role. However, the deposition is generally the entire surface plating, and the pattern needs to be made, so the etching is to remove the unwanted material to form the desired pattern.

How to choose the process engineer and Fab process engineer

The Process engineers in equipment plants are mainly responsible for the process verification of semiconductor equipment, the diagnosis, analysis and solution of process problems in equipment operation, and the improvement of design ideas with mechanical design engineers. The process engineers of the Fab plant are mainly focused on the product to ensure that the product does not have process problems in this process, all for the sake of product shipment and chip yield.

Therefore, the process engineers of Fab are in the first line of chip manufacturing and have a better understanding of the manufacturing process of chip products, while the process engineers of the equipment factory will contact many products of different customers for the machine. General Fab plant process engineers have a wider range of options.

How to choose etching and deposition?

In the field of semiconductor manufacturing, dry etching is more promising for most. Mainly because PVD,CVD is involved in many fields, a large number of practitioners, strong substitutable, such as optical lenses, filters, glasses, batteries, tools, etc. PVD,CVD coating will be used. The plasma etching process is a unique process in high-end industries such as semiconductor manufacturing and panels, and talents are relatively scarce and salaries are relatively high.
