ABSTRACT:
A thin material film for the manufacture of a semiconductor device is inspected in the presence of pinholes therein. This is achieved by forming a reactive material film which can gasify through a chemical reaction with a reactive solution on the surface of a semiconductor substrate and thin material film to be tested which can chemically resist the reactive solution is formed on the surface of the reactive material film, whereby the structure obtained by the above steps is immersed into the reactive solution.
