Abstract
There is provided a semiconductor device and a manufacturing method therefor, the semiconductor device requiring flip-chip mounting of a fine pitch electrode, wherein the fine electrode is easily manufactured, resin sealing is not required, and reliability can be improved. In the semiconductor device, one or more LSI chips (1), having an insulating layer (3) surface and an electrode (2) surface on one side, and a substrate (4), having an insulating layer (6) surface and an electrode (5) surface on one side, are bonded by having surfaces of the electrodes and surfaces of the insulating layers face each other via a bonding layer (7) made in a thin film form, in a region excluding the surfaces of the electrodes (2, 5) and the surfaces of the insulating layers (3, 6) in areas surrounding the electrodes.
