摘要： A stainless steel member for a separator of a solid polymer fuel cell has excellent cell properties with little deterioration in performance over long periods of operation without worsening of the corrosion resistance of a stainless steel separator. The stainless steel member has a stainless steel base metal, and a passive film and electrically conductive precipitates both provided on a surface of the stainless steel base metal. The electrically conductive precipitate penetrates the passive film and includes a substance originating from the stainless steel base metal. An electrically conductive layer comprising a nonmetallic electrically conductive substance is preferably provided on the surface of the passive film, and the electrically conductive layer is preferably electrically connected to the stainless steel base member through the electrically conductive precipitates.

摘要： A semiconductor device includes a first insulating layer and a second insulating layer in a trench. The first insulating layer insulates two MOSFETs from each other, and the second insulating layer has a true stress opposite to a true stress of the first insulating layer. The second insulating layer includes two regions of different true stresses. This enables a drain current flow in each MOSFET to be independently controlled in a semiconductor device that employs a STI method for element isolation.
