Patent JP-H02273971-A (JP)
Title: Semiconductor device having protective circuit
Inventor: REONARUDOUSU YOHANESU FUAN ROO
IPC: H01L27/02
Filed: 1990-03-12
Abstract: PURPOSE: To securely protect an integrated circuit against a voltage generated by a connection conductor although it has an active area coated with a method silicide by making a protection element substantially as wide as the active area. CONSTITUTION: A resistance element 9 is connected between an electrode 16 to which the active area 81 is connected and a p-n junction 86 in series with the protecting element 8, and this resistance element 9 has an (n) type area 91, which is positioned in a substrate 10 and substantially as wide as the active area 81. This resistance element 9 comes into direct contact with the active area 81, which is done by making the resistance area 91 contiguous to the active area 81 of the protecting element 8; and the majority of a resistance area 91 is below a sunk silicide layer 12. In this case, as the p-n junction is positioned closer to the oxide layer 12, a current becomes harder to flow to the p-n junction 86 through the active layer 81. Specially, when the active area 81 is relatively short, a substantially uniform current distribution can be obtained over the p-n junction 86.  Consequently, the integrated circuit can securely be protected.
