Title: Manufacture of semiconductor device
Inventor: OGURA TSUNEO
IPC: H01L29/73
Filed: 1981-04-24
Abstract: PURPOSE:To perform a high-speed operation for the subject semicondutor device without impairing the high withstand voltage and large output current of SCR by a method wherein a heavy metal is ion-implanted in the Si substrate, having an N-layer containing V-group element, and the above is processed at a high temperature for a long hours. CONSTITUTION:Au atom is ion-implanted from the side of the N-emitter layer 21 of the SCR of NPNP constitution having an N-layer with the phosphorus concentration of 2X10<18> atom/cm<2>, processed at the temperature of 900 deg.C or above for an hour or more, and an Au diffusion is performed. At this time, the density of the Au is not affected by the phosphorus of high density contained in the N-emitter layer 21, the above density is controlled, independent from the temperature, by the quantity of ion-implantation, and a high-temperature diffusion can be performed uniformly. Thus, the density distribution of the Au is uniformalized in four layers, the shortening of life of the N-emitter, a P-base and a P-emitter which give no effect for the turn- off time is prevented, the enhancement of forward voltage drop of the SCR is also prevented, and the high withstand voltage and the large output current for the subject device can be obtained. Also, the life in lateral direction can be uniformalized. According to this constitution, the readjustment and fine adjustment of the turn-on time are simplified, and a high-speed operation can be performed for the subject device. Elements other than the SCR can be utilized for the uniformity of the heavy metal distribution.
