    摘要: A bipolar silicon transistor includes at least one emitter zone with n.sup.+ arsenic doping and with a phosphorus doping. The ratio between arsenic dopant concentration and phosphorus dopant concentration is between 10:1 and 500:1 in the at least one emitter zone. The at least one emitter zone may also have a penetration depth of less than 0.5 .mu.m. A method for producing a bipolar silicon transistor includes implanting a n.sup.+ -doped emitter zone with arsenic, implanting the n.sup.+ -doped emitter zone with phosphorus, setting a ratio in the n.sup.+ -doped emitter zone between the arsenic dopant concentration and phosphorus dopant concentration to between 10:1 and 500:1, and annealing crystal defects.
