IPC: H01L29/167
Filed: 1990-12-19
Abstract: PURPOSE: To improve low-temperature current gain by doping a base region with first and second impurities of a second conduction type and enabling the second impurity to have a higher ionization energy than that of the first impurity. CONSTITUTION: A second impurity of p-type conductivity is injected, in addition to the p-type doping of a base region 26.
