Filed: 1981-12-22
Abstract: PURPOSE:To detect the film thickness of thin films formed by plating films and to offer a method easily detecting the end point of the film formation by a method wherein monitoring base film patterns are provided. CONSTITUTION:A conductive base film 2 consisting of copper or the like is formed on a substrate 1 having insulation on the surface by a sputtering method. A part of the base film 2 is patterned to form monitoring base film patterns 2'. Insulating mask films 3 such as resist are formed on the base film 2 with predetermined patterns. Conductive thin films 4 consisting of Cu are formed by using the mask films 3 as masks and by a plating film formation method. This plating is applied by immersing the conductive films 4 in a copper sulphate solution. At that time, the thin films 4 formed on the monitor patterns 2' transversely promote film formation as no mask films exist. Each thin film 4 is shortly connected to short-circuit each monitoring base film pattern 2'. The short circuit is immediately detected by a detection section D to send a signal informing the completion of film formation.
