The Eight Major Semiconductor Technologies (III) - Integrated Circuits: An Electronic Revolution
During the "oxidation" step, an oxide layer (SiO₂) is formed on the surface of the wafer. The wafer is the most important material in semiconductor processing. The oxide layer protects the surface of the wafer from impurities, and the next step is to design the semiconductor circuit. What does the circuit in a semiconductor chip look like? Let's learn together! Micro semiconductor chips contain thousands to millions of electronic components (diodes, transistors, capacitors, resistors) within them. How are these semiconductor integrated circuits made? Let's first understand a bit of the history of semiconductor development. Transistors: Where the Electronic Revolution Began In 1947, researchers at Bell Laboratories, the central research facility of the largest telecommunications company in the United States, American Telephone and Telegraph (AT&T), invented the transistor. This invention was initially called the "amplifier" and later renamed as the tran...
