Title: Production of metallic mask
Inventor: HOSONO KAZUMASA
IPC: C23F1/00
Filed: 1981-01-12
Abstract: PURPOSE: To produce a metallic mask having apertures of good dimensional accuracy by depositing a thin metallic layer on the surface of a substrate having weak adhesive force to the material metal of the metallic mask and opening the apertures of a prescribed shape by a photoetching method.  
     CONSTITUTION: For example, a permalloy layer 2 is formed by sputtering to about 10μ thickness over the entire surface of a rock crystal or glass substrate 1 having a clean surface. Thence, a resist layer 3 is formed on the layer 2, and apertures 4 of a prescribed shape are formed by an ordinary photoetching method. Next, when the layer 3 is removed and a self-adhesive tape 5 is adhered to the end part of the layer 2 and is pulled, the layer 2 is stripped from the substrate 1. Since the thickness of the layer 2 is as thin as about 10μ, side etching in photoetching is less and a metallic mask 6 having apertures 4 of good dimensional accuracy is obtained.
