Abstract: A pressure sensor has a stem in which a pressure introduction hole into which a pressure medium is introduced and a diaphragm deformable according to the pressure of the pressure medium are formed, and a strain detecting element which is arranged on the diaphragm via an insulating film and being configured to output a detection signal according to the deformation of the diaphragm. The strain detecting element is configured to have a portion made of polysilicon. A low doping layer having a higher electrical resistivity than polysilicon and a higher crystallinity than the insulating film is arranged between the insulating film and the strain detecting element.

Abstract: A method for manufacturing a wiring board offering efficient operations of peeling and collection of a protective film as well as preventing a lowered yield. A method for manufacturing a build-up multilayer resin wiring board, which includes a taping process S2 and a peeling process S3. In the taping process S2, two sheets of substrate are supported and adjoined under the condition that the edges thereof are placed close to each other, and a tape is affixed so that the protective film may be connected on the edge of the substrate. In the peeling process S3, the protective films connected to each other are continuously peeled by sequentially lifting them via the tapes so that an interlayer insulation material may remain on the substrate.
