PCT No. PCT/JP95/00493 Sec. 371 Date Sep. 17, 1997 Sec. 102(e) Date Sep. 17, 1997 PCT Filed Mar. 17, 1995A semiconductor device capable of meeting the demand for fine-pitched wiring of semiconductor element and highly dense mounting thereof, as well as the demand for a thin structure thereof, which device being superior in the adhesion property of an insulating resin to be used for sealing a semiconductor element and a film carrier, and thus highly reliable. In FIG. 1, a conductive circuit (5) is embedded so that it will not be exposed at the both surfaces (6a, 6b) of an insulator layer (6), and conductive paths (7, 8) are formed in a pair from the both surfaces (5a, 5b) of the conductive circuit (5), the conductive paths slipping relative to each other in the direction of the surface of the conductive circuit (5). The conductive paths (7, 8) are respectively connected to bumps (9, 10), and the conductive circuit (5) and bumps (9, 10) are conducted via conductive paths (7, 8). The bump (9) formed on one end of the one conductive path (7) of the film carrier (2) contacts an electrode (12) of the semiconductor element (3) and is electrically connected, whereby the semiconductor element (3) is mounted on the film carrier (2). An insulating resin layer (4) is formed on one surface (6a) of the insulator layer (6) to cover the semiconductor element (3).
