Patent JP-H0439950-A (JP)
Title: Semiconductor device
Inventor: NAKAMURA ISAO
IPC: G01R31/26
Filed: 1990-06-05
Abstract: PURPOSE:To avoid cracks in a layer inside an electrode pad upon test probing for a semiconductor device and to prevent defectives before packaging by forming a probe pad in the vicinity of an electrode pad. CONSTITUTION:A probe pad 24 is formed via a bridge 23 on the side of each electric pad 22 of the outer periphery of a semiconductor chip 20. The pad 24 is electrically connected to each pad 22 via a part 23. During probe check, a protection layer 2 endures the load of a probe 25 because of location of this layer under a pad 24, thereby avoiding defectives of a device. It follows that a circuit layer under the protection layer 21 is prevented from becoming faulty due to cracks and the like. This enables test by bringing a tester probe with the pad 24, so that defectives can be prevented. Therefore, semiconductor devices free from faults can be realized in the case of packaging using film carriers or the like.

Title: Operation system semiconductor memory
Inventor: TOKUSHIGE KAORU
IPC: G11C14/00
Filed: 1980-10-22
Abstract: PURPOSE:To convert a function of a writable ROM to that of a static RAM, by a pulse for erasing a non-volatile information which is inputted to the gate of an MNOS transistor. CONSTITUTION:An electrically writable ROM (EAROM) erases an old information and also stores a new information by applying erase pulse voltage and a write pulse to N-MNOS transistors TRs 15 and 16 from a pulse voltage signal line (MG line). That is to say, after the old information is erased, one of the TRs 15 and 16 becomes a depression type and the other an enhancement type, therefore, information is stored and also written information is reduced to non-volatile. In the memory cell which is operated as EAROM in this way, negative pulse voltage is applied to the gates of the TRs 15 and 16 from the MG line. As a result, both the TRs 15 and 16 become a depression type, and the memory cell functions as a static RAM constituted of a conventional C-MOS.
