what is a silicon wafer
Key parameters for wafer procurement
Size: ranging from 2 inches to 12 inches, the increase in size is directly related to the number of chips that can be produced on a single wafer, which in turn affects the overall production efficiency.
Crystal orientation: Specific crystal orientation choices such as (100), (111), etc. have a decisive impact on the final performance of the semiconductor device and the manufacturing process path.

Type and Doping: Distinguished as P-type or N-type and accompanied by specific doping concentrations, these determine the conductive properties of the wafer and are the basis of semiconductor design.
Resistivity: As a key indicator of wafer purity and impurity content, it directly affects circuit stability and performance performance.
Surface Coating: Check whether it is covered with an oxide layer or other protective layers, which are critical for subsequent process steps.
Thickness: Needed to precisely match the technical requirements of a given application.
