Abstract:
An electronic device having a wiring substrate with a plurality of electrodes on a principal surface thereof and also having a first semiconductor device and a second semiconductor device both being mounted on the principal surface of said wiring substrate, whereinsaid first semiconductor device comprises: a semiconductor chip having first and second principal surfaces opposing each other, first and second electrodes formed on the first principal surface, and a third electrode formed on the second principal surface; a first lead having a first portion placed over said first electrode and a second portion being formed integrally with said first portion and placed outside of said semiconductor chip; a second lead having a first portion placed over said second electrode and a second portion as formed integrally with said first portion and placed outside of said semiconductor chip; a plurality of projected electrodes disposed between said first lead and said first electrode and also between said second lead and said second electrode for electrical connection of respective ones of them; and an insulative sheet disposed between said first lead and the first principal surface of said semiconductor chip and between said second lead and said semiconductor chip for covering a certain part of the first principal surface of said semiconductor chip other than a region with said plurality of projected electrodes disposed therein, wherein a respective one of the second portions of said first lead and said second lead is folded to have a distal end disposed at substantially the same height as the second principal surface of said semiconductor chip in a thickness direction of said semiconductor chip, and each of said third electrode and the distal ends of the second portions of said first lead and second lead is connected to a corresponding electrode of said wiring substrate.
