IPC: H01L21/8249
Filed: 1982-03-26
Abstract: PURPOSE:To adequately adjust the impurity density of each region surface by a method wherein a heat treatment is performed in a wet atmosphere, after etching the other region surface in the state of covering one region with a mask material. CONSTITUTION:The impurity of boron 9 is introduced through the mask for boron diffusion into the surface of an epitaxial layer 3 at a density high than at the time of normal formation of a well. After forming an Si, an SiO2 film, or an Si nitride film 10, the vapor chemical precipitation film on a well part is etched, thus a part of an epitaxial layer 3 is exposed, and the surface thereof is etched resulting in the removal of the surface layer wherein boron is introduced at a high density. By performing a heat treatment in a wet atmosphere, the impurity of boron is extended and diffused deep inside, thus a P-base layer 6 is formed, and a P isolation 7 and a P-well 8 are formed.

Title: Method and device for detecting recording medium and method of inspecting recording/reproducing device
Inventor: TANAKA SHINICHI
IPC: G11B20/18
Filed: 1990-02-28
Abstract: PURPOSE:To directly evaluate frequency characteristics by repeatedly recording a prescribed pattern which may easily generate a timing shear due to inter-code interference in a recording medium in which digital information is to be recorded, and at the time of reproducing, measuring the average value of timing shears on the prescribed part. CONSTITUTION:Data are constituted of binary digital information consisting of '0' and '1' and '1' corresponding to a binary value '1' is optically recorded on the recording medium. Since pulse width is changed in accordance with the existing state of marks 1 in a mark string, i.e. whether the marks 1 are continued or intermittently exist through intervals at the time of obtaining a reproduced signal 2 by reading out the mark string, the pulse width is measured as a time interval in which plural thresholds 3 intersect with each other. When the timing shear of a pulse edge is measured by procedure, the frequency characteristics of a recording/reproducing head are measured as a format matched with the practical using format and recording power is optimized by searching the minimum position of the shear value.
