Patent JP-H10178118-A (JP)
Title: Method of manufacturing semiconductor device
Inventor: OTA KATSUHIKO
IPC: H01L21/8249
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To prevent the troubles caused by contamination resulting from the etching step in the case of sidewall formation by providing a step of removing the contamination in the bipolar transistor forming region caused in the MOS transistor forming region. SOLUTION: A contaminated layer is etched away to remove contamination by a plasma etching device. In details, the contaminated layer is removed by etching away a substrate surface by about 10nm using a downstream type plasma etching device. Thus, the bipolar transistor characteristic is recovered and the hFE/Ico is recovered. That is, e.g. at 0.5V of base-emitter voltage, the base current is lowered to a value which is about one order of magnitude smaller and the leakage current is decreased. Furthermore, even if, the entire surface of a mask forming film (SiO2 film) is etched back to etch for performing the mask processing step of the sidewall of a gate structure 2 leaving only SiO2 sidewall 4 intact, the problem of causing troubles by this step can be settled.
