The semiconductor support industry mainly includes semiconductor materials, semiconductor equipment and semiconductor software services:
Semiconductor equipment: semiconductor equipment is mainly used in wafer manufacturing and packaging testing. As there are many semiconductor processing procedures, a large number of semiconductor manufacturing equipment are required in the manufacturing process. For example, lithography machine, etching machine, chemical vapor deposition and other equipment.
Semiconductor materials: There are many kinds of semiconductor materials, including substrates (silicon chips/sapphires/GaAs, etc.), photoresists, electronic gases, sputtering targets, CMP materials, masks, electroplating solutions, packaging substrates, lead frames, bonding wires, plastic packaging materials, etc. It also needs many materials such as photoresist, special gas, etching solution, cleaning solution, etc.
Semiconductor software service: semiconductor software is mainly used in the IC design process. After the product specification is designed, hardware description language (HDL - commonly used Verilog, VHDL, etc.) is required to describe the circuit, and then the synthesized code is put into EDA tool for circuit layout and winding
