摘要:
A method of patterning an indium tin oxide film includes the steps of forming a cap layer over the indium tin oxide film and subjecting exposed areas of the indium tin oxide film to a water plasma.
摘要:
An pure H2O stripping process for etched metal wafers effectively solves the metal corrosion deficiencies induced by O2, N2 plasma charging. The pure H2O plasma stripping releases and neutralizes the storage of positive charge accumulated in the wafer, reduces chlorine concentration, and effectively strips the photoresist and etching residue. Thereby reducing metal corrosion and increases the anti-metal corrosion window. The pure H2O plasma stripping requires no additional equipment and or steps.

摘要:
Disclosed is a method and a system for wafer backside alignment. A zero mark patterning on front side of a substrate. A plurality of layers are deposited on the front side of the substrate. The wafer is flipped over with backside of the substrate facing up, and a through wafer etching is performed from the backside to an etch stop layer deposited over the front side of the substrate.

摘要:
A method for wafer backside alignment overlay accuracy includes forming a buried layer on a front-side of a wafer; forming a conductive layer on the buried layer and patterning a first test structure and a second test structure therein; forming an etch stop layer on the conductive layer; etching through the wafer from the backside to perform an alignment process with the first test structure; and determining an overlay accuracy of the alignment process with the second test structure. The first test structure includes an optical vernier and the second test structure includes an electrical testing structure.
