An integrated circuit (IC) is a tiny yet powerful electronic component that integrates hundreds to billions of electronic devices on a small chip. It integrates the functions of electronic circuits such as storing, processing and transmitting information. The high level of integration of ICs makes them the core of various electronic devices, from computers to communication devices, everywhere, supporting modern technology and digital life. Integrated Circuits (ICs) play a key role in modern technology and have a wide range of applications, including but not limited to the following several aspects:

1. Electronic equipment and consumer goods:

1). Communication equipment: mobile phones, wireless routers, satellite communication equipment, etc.

2). Entertainment equipment: TV, audio system, game console, etc.

3). Personal electronic products: laptops, tablets, smart watches, etc.

2. Computers and Data Storage:

1). Central processing unit (CPU) and microcontroller: used in computers and embedded systems.

2). Storage devices: flash memory, RAM (random access memory), ROM (read-only memory), etc.

3. Medical and medical equipment:
