Abstract: A method for manufacturing a semiconductor device includes: forming an insulating film on a surface of a semiconductor layer of a semiconductor substrate; forming a contact hole in the insulating film; forming a conductor material on the insulating film to be in contact with the semiconductor layer through the contact hole; and patterning the conductor material using an alignment key included in the conductor material.

Abstract: A substrate includes a primary circuit; a secondary circuit; and a ground (GND) patterns. In a path between the primary circuit and the secondary circuit without passing through the GND pattern, reinforced insulation is provided between the primary circuit and the secondary circuit. In a path between the primary circuit and the secondary circuit through the GND pattern, one of 1) a combination of reinforced insulation and functional insulation and 2) a combination of basic insulation, additional insulation, and functional insulation is provided between the primary circuit and the secondary circuit.

Abstract: A mobile information apparatus 10 acquires the display information which is stored in the display area 72, which is secured for using at the time of displaying on the display section by the mobile information apparatus 10, in the storage section 34 of the contactless communication device 30. In this case, in the display area 72, display information which can improve convenience for a user is stored. The display information which is stored includes information such as a result of editing a content of communication performed by the contactless communication, a function performed by the contactless communication by the contactless communication device 30, and an issuer of such function. Then, based on the display information which is acquired, the information of the contactless communication device 30 is displayed on the display section.
