IPC: H01L23/28
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To accurately perform lead forming of outer lead by positioning a resin sealed semiconductor device at an accurate machining/fixing position. SOLUTION: A resin sealed semiconductor device is arranged at a bending position along a supporting table 31 and adjusted automatically to an accurate machining/fixing position, by pressing a pair of inclining faces 60, 61 of a holder 55 against side faces 4a, 4b at a base part 4 of a resin sealed body 2.
