A lead frame which enables a plurality of semiconductor chips to be mounted and which has hang pins, and a semiconductor device using the lead frame. The lead frame includes a main bed section (21) which is supported by support pieces (22) extending from a frame section (19) and on which a main semiconductor chip (25) is mounted, a plurality of lead pieces (20) whose ends extend from said frame section to be positioned near said main bed section and to be opposed to each other, some of the lead pieces having sub-bed sections (23) at any portions thereof on which sub-semiconductor chips (26) will be mounted, and hang pins (24) that extend from said frame section nearly in parallel with said lead pieces on the outside of lead pieces (20A) located on the outermost side, and that are sealed together with said lead pieces in a sealing resin in a resin-molding step in the steps of producing semiconductor devices. There is realized a semiconductor device having a high mounting density. <IMAGE> |
