Title: Semiconductor device
Inventor: YOSAKO TOSHIHIRO
IPC: H01L23/522
Filed: 1987-03-31
Abstract: PURPOSE:To avoid the step-cut of an Al wiring film and the fluctuation of a contact resistance caused in a contact hole by a defective contact hole shape by a method wherein the uppermost layer of a multilayered insulating film has a higher etching rate than the other insulating layers. CONSTITUTION:When a contact hole is formed with a photoresist film 6 as a mask, isotropic etching is carried out first. With this process, as the selection ratio between the etching rates of a plasma nitride film 5 and a plasma oxide film 8 is large, only the inter layer insulating film 5 built up above the plasma oxide film 8 is etched and the plasma, oxide film 8 is left without being etched. Then, if anisotropic etching is carried out, as the size and depth of the contact hole formed by isotropic etching are uniform, the plasma oxide film 8 is accurately etched to expose the surface of a lower layer wiring Al film 4. With this constitution, as the insulating layer between the 1st layer wiring and the 2nd layer wiring of a multilayer interconnection is composed of an insulating film of a double-layer structure constituted by two types of insulating layers with different etching rates, the contact hole has a wine cup shape opening upward and the variability of treatment can be suppressed so that an interconnection whose stepped parts can be covered well can be obtained.
