Latest Patents

Otani holds a patent for a method of forming wires on an integrated circuit chip. This damascene method involves etching trenches using a plasma formed by capacitively coupling a gas mixture at power levels ranging from 500 to 3000 watts under a pressure of 50-400 mTorr. The gas mixture consists of 2-30 sccm of C, F, 20-80 sccm of CO, 2-30 sccm of O, and 50-400 sccm of Ar. The gas flow can be adjusted to achieve an optimal level, ensuring a high degree of uniformity. Wafers that fall below a selected uniformity can be reworked. The damascene wiring layer formed in the trenches exhibits a high degree of sheet resistance uniformity and improved line-to-line shorts yield.
