Patent JP-S59149045-A (JP)
Title: Semiconductor device
Inventor: YOSHIKAWA KIMIMARO
IPC: H01L23/52
Filed: 1983-02-16
Abstract: PURPOSE:To reduce base resistance by isolating base regions of a plurality of reverse operation vertical type transistors by an insulator and reducing base ineffective areas while the base regions are connected mutually by an extracting electrode consisting of a metallic silicide layer formed in a self-alignment manner. CONSTITUTION:Inverter transistors T1, T2 are isolated by an oxide 41, and an injector transistor T4 is also isolated and made independent. A common base connects the bases 34 of each incerter transistor and a coolsector 36 of an injector by an extracting electrode 34' consisting of polycrystalline silicon remaining through selective oxidation and platinum silicide 34'' formed in a self- alignment manner. Since the extracting electrode has platinum silicide, its resistance can be brought to a very low value, and base series resistance can be reduced. Consequently, a base lateral voltage drop is not generated even by the increase of the number of collectors, and uniform current gains are obtained, thus remarkably improving the speed of switching. Since sections except intrinsic transistor regions are also isolated by oxides in each inverter transistor, parastic capacitance is small, and the ratio of a collector area to a base area is large, thus also improving current gains.
