What Is a Silicon Integrated Circuit?

Silicon for integrated circuits, silicon polishing wafers and wafers for integrated circuit manufacturing.

Silicon for integrated circuits

Right!

Silicon for integrated circuits, silicon polishing wafers and wafers for integrated circuit manufacturing.

As the integration of IL increases, the requirements for the intrinsic quality and geometric dimensions of silicon materials become higher and higher, including impurity content, defect density, cleanliness, precision, and wafer diameter. According to the type of circuit, the requirements for silicon materials are as follows:

For ultra-large-scale integrated circuits, the size of the device must be micron, and the production of epitaxial wafers must be made. As the integration level increases, the die area increases, and the number of fabrications increases. Using larger-diameter silicon wafers can achieve greater economic benefits. benefit. ^[1]
