Title: Bipolar semiconductor device
Inventor: IWASAKI HIROSHI
IPC: H01L21/8226
Filed: 1985-03-07
Abstract: PURPOSE:To obtain the high velocity and the reliability by making a junction shallow by using the polycide doped with impurity as a diffusion source and an electrode of an impurity region. CONSTITUTION:In the bipolar semiconductor device, the impurity concentration doped in a polycide lamination film is controlled to be a proper value so that emitter diffusion and collector diffusion of I<2>L of an NPN transistor are effected normally and the good characteristic of high-velocity operation due to a shallow junction can be obtained. A resistance value of a high-melting-point metal silicide layer 3 composing the polycide lamination film is low and this contributes to the prevention of enhancement of the resistance of electrode wirings 34, 351, 352, 36, 371, and 372 made of the polycide. Accordingly, the emitter resistance of NPN is restrained to a few OMEGA which is a sufficiently low value compared with the conventional values 10-20OMEGA and it is possible to further improve the high-velocity characteristics of the vertical NPN transistor compared with a conventional one.
