Patent JP-S63136668-A (JP)
Title: Manufacture of semiconductor device
Inventor: ITO SHINICHI
IPC: H01L29/40
Filed: 1986-11-28
Abstract: PURPOSE:To obtain the emitter stabilized resistance as well as a pn junction passivation film and reduce sticking of a polysilicon film as well as frequency of a photoetching treatment by diffusing impurities in an emitter and a part to be equipped with the emitter stabilized resistance at the polysilicon film on the surface of a pn junction without diffusing the impurites in the part to be equipped with a resistance sheet on the surface of the pn junction. CONSTITUTION:Respective regions of a collector 2, a base 3, and an emitter 4 are formed at a substrate 1. And a pn junction between the collector 2 and the base 3 is exposed at the surface of the substrate 1. And then, a silicon oxide film 5 is provided at the whole surface of the substrate 1 and a polysilicon film 6 is sticked on the above film 5. Subsequently, a resist film is applied to an upper face of the film 6 and only the resist film 7 that is located at the upper side of a part where the pn junction between the collector 2 and the base 3 is exposed at the surface of the substrate 1 is left as it is at least. Under this state, for example, phosphorus is implanted as an impurity by an ion implantation 8 and are diffused through a heat treatment at an elevated temperature. As a result, the polysilicon film 6-1 with a high resistance where the impurity are not diffused is obtained as a passivation film at the upper side of the part where the pn junction between the collector 2 and the base 3 is exposed at the surface of the substrate and on the emitter 4 the impurities are diffused as the stabilized resistance and then, the polysilicon film 6-2 with a low resistance is obtained.

Inventor: SATO EIICHI
IPC: H04N1/32
Filed: 1990-10-22
Abstract: PURPOSE:To reduce the probability of transmission interruption to easily transmit data of still pictures or the like of large information volume by skipping the step, where one is added to an error counter, in the case of the reduction of the number of error frames due to retransmission. CONSTITUTION:The video signal inputted from a video signal input terminal 12 passes a memory controller 8, a picture memory 9, and a MODEM 4 and is outputted from a telephone line connection terminal 7. Meanwhile, the reception signal passes the controller 8, the memory 9, and a video encoder 14 from the terminal 7 and is outputted to the outside from an output terminal 15. If the number of error frames stored in a RAM 2 is smaller than the number of frames transmitted, again by preceding retransmission, a CPU 1 regards error as recovered and continues transmission without incrementing the error counter.
