摘要:
A process for producing a semiconductor device which comprises forming a layer of an organic polymer resin on a surface of a semiconductor element, treating the formed layer by pattern working and curing, etching the element using the patterned and cured layer as a mask, exposing an electric conductive layer at open portions, treating the element with oxygen plasma at a temperature of 100° C. or higher and cleaning the electric conductive layer at the open portions. When the electric conductive layer at open portions is cleaned by the oxygen plasma treatment, formation of cracks on the organic protective layer is suppressed and adhesion between the organic protective layer and a sealing resin is improved.
