IPC: H03H3/08
Filed: 1990-05-16
Abstract: PURPOSE:To improve the electric characteristic and the yield by using a material having etching selectivity to aluminum for materials for a bonding pad and a wiring electrode, forming an interdigital electrode at first, and forming the bonding pad and the wiring electrode directly with etching. CONSTITUTION:At first a metallic aluminum comb-line electrode 2 whose film thickness is, e.g. 0.1mum is formed by the direct etching process by means of the micro process technology such as photolithography. Then a chromium whose film thickness is, e.g. 0.1mum is vapor-deposited on the interdigital electrode layer 2 and gold whose film thickness if 1mum is vapor-deposited on the interdigital electrode layer 2 continuously. Then a bonding pad 3 and a wiring electrode pattern 4 for photo resist are formed by the photo lithography. The gold and the chromium are etched directly by using the photo resist pattern as an etching mask and the photo resist is removed. Thus, the linearity at the aluminum comb-line electrode end is enhanced and the electric characteristic is improved and the yield is improved.
