it might cause damage to the transistors and degrade its performance. During the fabrication process, we need to etch out the unwanted oxide layer from the wafer, which can be done using plasma ...

Etching seems like such an old-fashioned technique ... The printing creates multiple electronic components such as transistors, resistors, and capacitors – crucial in the functions of integrated ...

When an etching chemical is applied those soft parts ... a pattern of polysilicon (which does conduct electricity and is part of the transistor) is added. Then, again using projected photoresist ...
