Inventor: BABA TOSHISUKE
IPC: H01L23/58
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To block surge current into an internal circuit. SOLUTION: When positive or negative surge voltage is applied to a pad 1c, a PMOS or NMOS diode of a protective circuit 1b is turned on to flow surge current into a power supply or the ground, and a part of the surge current flows into a board 1 through the protective circuit 1b. An internal circuit 2a is formed on a board 2 different from the board 1, thence the surge current can not flow into input and output terminals of the internal circuit 2a. Also the input and output terminals of the internal circuit 2a are connected via a load resistance and solder bumps 3 composed by the protective circuit 1b and the load resistance is much larger than the on-resistance of the diode, thence the surge current can not flow into the internal circuit 2a. Thus the internal circuit 2a is prevented from malfunctioning.
