Title: Preparation for insb semiconductor device
Inventor: TSUNODA REIKICHI
IPC: H01L29/78
Filed: 1985-08-13
Abstract: PURPOSE:To form on the surface of an InSb substrate, a high density impurity region of high quality which has the different conduction type with each other, by changing the thicknesses of layers which are eliminated by etching in the process of anodic oxidation film etching by a donor ion implantation layer and the acceptor ion implantation layer. CONSTITUTION:An N<+> layer 33 formed by Si ion implantation and a P<+> layer 32 formed by Mg ion implantation are constituted on the surface of an InSb substrate 31. After an SiO2 film 34 is formed, the region containing the boundary line of the N<+> layer 33 is eliminated by the resist pattern etching method, and the surface of the substrate 31 is subjected to an anodic oxidation. After that, the anodic oxidation and etching exfoliation are repeated to exfoliate the N<+> layer 33 by the thickness of 50-60nm. Then the SiO2 film 34 is eliminated, and the anodic oxidation and exfoliation are performed repeatedly by the same method. Thereby the whole surface of the substrate 31 is exfoliated by the thickness of 30-60nm, and the InSb device whose N<+> layer 33 is exfoliated more deeply than a P<+> layer 32 can be obtained.

Filed: 1987-07-16
Abstract: PURPOSE:To stably erase an echo signal by detecting the utterance of a nearby talker by a 2-way simultaneous talking detection stage and stopping the deduction of an echo path of an echo canceller when a narrow band signal detection means detects a received input signal to be a narrow band signal. CONSTITUTION:A narrow band signal detection means 7 decides whether or not a received input signal is a narrow band signal and an AND means 10 ANDs the decision result of the 2-way simultaneous talking detection means 6 with the discrimination of the narrow band signal detection means 7 to control the echo canceller 5. That is, when the 2-way simultaneous talking detection means 6 decides it that a nearby talker utters, the means 7 decides the reception signal to be in the narrow band so as to allow the deduction of the echo path characteristic of the echo canceller 5 to be stopped. Thus, erroneous characteristic deduction by the narrow hand signal is avoided and the echo canceller deducts the characteristic of the echo path correctly and the echo signal is erased stably.
