Wafer txhais
Wafer yog hais txog cov silicon wafer siv rau ua cov roj hluav taws xob semiconductor sib xyaw ua ke, thiab nws cov khoom siv qub yog silicon. Lub siab-purity polysilicon yog yaj thiab doped nrog silicon siv lead ua cov noob, thiab tom qab ntawd maj mam rub tawm los ua cov cylindrical ib leeg-siv lead ua silicon.
