THICK BOND PAD FOR CHIP WITH CAVITY PACKAGE |
摘要 |
Disclosed herein a method, including depositing a silicon nitride layer over an inter layer dielectric (ILD); depositing a first conductive layer having a first thickness; forming a mask over a first portion of the first conductive layer to expose a second portion of the first conductive layer; etching the first conductive layer; etching the silicon nitride layer with a fluorine-based etch; and depositing a second conductive layer having a second thickness. |
