This video provides an overview of semiconductor manufacturing, highlighting the complex processes involved in creating these essential components. It begins with the raw material, sand, which is turned into silicon. Silicon is then transformed into highly pure monocrystalline ingots. Doping is explained, where impurity atoms are added to make silicon conductive.
The video discusses the construction of transistors, the building blocks of microchips, and their role in controlling electrical currents. It covers the design and layout phase, emphasizing the need for a clean room environment. The fabrication process includes steps like oxidation, etching, and doping, and it is repeated to create multiple chips on a single wafer.
Finally, it describes the assembly of chips into packages and their use in various applications, including power semiconductors. Quality control and precision are essential throughout the process, as semiconductor technology continues to play a vital role in making life easier, safer, and more sustainable.
