WebMar 19, 1997 · Abstract: Molybdenum films have been deposited by sputtering for integrated circuit metallization. The sputtering system used in this study is a sideways depositing batch unit with a rotating wafer drum, operating at a base vacuum range below 5.10 -7 mbar. We have experimentally observed that a Ti-W seed layer deposited underneath molybdenum … WebA bulk acoustic wave (BAW) resonator includes: a substrate; a piezoelectric layer disposed above the substrate; a first electrode disposed below the piezoelectric layer and including a first portion and a second portion spaced apart from each other; a second electrode disposed above the piezoelectric layer; a first dielectric layer, a second dielectric layer, … WebThe TiW seed layer provides improved plating uniformity and significantly increased conductivity as compared to a Ta/TaN conducting seed layer. In addition, the use of TiW as described below addresses sputtering concerns of Ta/TaN on polyimides, as well as gold loss during reactive ion etching. rcgp top tips insomnia
