Title:
SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/154072
Kind Code:
A1
Abstract:
A semiconductor device of the present invention is provided with a first insulating resin section (7) for sealing a mounting surface (2a) of a lead frame (2), and a second insulating resin section (8) for sealing a heat dissipating surface (2b) of the lead frame. The second insulting resin section (8) contains a filler (18) having a maximum diameter of 0.02-0.075mm, the second insulating resin section (8) has a thin portion forming section (10) that is formed in contact with the heat dissipating surface (2b) of the lead frame (2), and the thickness of the thin portion forming section (10) is 1.1 to 2 times the maximum diameter of the filler (18). The semiconductor device has a mixed layer, in which the resin of the first insulating resin section (7) and that of the second insulating resin section (8) are mixed at an interface between the first insulating resin section and the second insulating resin section.
