Those who understand semiconductors know that lithography machines are the core equipment for manufacturing chips. Without it, it is difficult to manufacture advanced chips. But in reality, another key equipment in the chip manufacturing process, the etching machine, is also very important. Etching machines may not be as difficult as lithography machines in terms of technology, but they are also an indispensable part of chip manufacturing, mainly reflected in their large proportion of investment equipment in manufacturing and the indispensable working principle in manufacturing.
In the process of chip manufacturing, the lithography machine has already completed its work, so it is necessary to start secondary processing from the etching machine to form a complete chip manufacturing process chain. It can be said that the etching machine is an essential equipment after photolithography and an important link in assisting the operation of the lithography machine.
