Title: Manufacture of dielectric isolating substrate
Inventor: OWADA NOBUHITO
IPC: H01L27/12
Filed: 1994-06-06
Abstract: PURPOSE:To prevent the defective joining of joint surfaces by thermally treating a laminated wafer in the direct joining of polycrystalline silicon and single crystal silicon within a specific temperature range as the heat treatment of the wafer. CONSTITUTION:In the heat treatment process of a wafer after laminating during the direct joining process of the wafer, the temperature of heat treatment correlates with the generation of voids. Consequently, it is considered that the temperature of heat treatment correlates with the generation of the voids even in the direct joining of polycrystalline silicon and single crystal silicon, and the generation of the voids to the temperature of heat treatment is examined. The result of the examination is shown in a graph. The axis of abscissas in the graph represents the temperature of heat treatment after laminating and the axis of ordinates the fraction defective of the joining of joint surfaces. The fraction defective of joining is reduced with a temperature rise, and a region, in which no defective joining is generated, is obtained within the range of a temperature of 1150-1250 deg.C. When the temperature is elevated to 1250 deg.C or higher, the fraction defective of joining is augmented again. Accordingly, the temperature of heat treatment after laminating is optimized, thus hardly generating defective joining.

Title: Method and apparatus for detecting defect in surface layer
Inventor: SUZUKI YOSHIAKI
IPC: G01N29/04
Filed: 1984-06-18
Abstract: PURPOSE:To detect a defect existing near the surface of an object to be inspected satisfactorily, by making an ultrasonic beam incident into the surface thereof with the frequency being varied by several stages to measure and compute surface echoes and combined echoes at respective frequencies. CONSTITUTION:A vertical probe 1 is kept in contact with the surface A without defects of an object 3 to be inspected and an ultrasonic beam is made incident thereinto, for example, at 3MHz. Consequently, a surface echo 7 is reflected with the height thereof being Ps. Then, when an ultrasonic beam is made incident into the surface B with defects, a cominbed echo of the surface echo 7 and a defect echo 6 is reflected with the height being Ph. The frequency of the ultrasonic beam is shifted to 30MHz and the same operation is done to determine the height P's of the surface echo at a point without any defect and the height P'h of te combined echo at a point with defects. As the echo heights Ps, Ph, P's and P'h are in a correlation with the distance and size of the defect, an arithmetic control section 13 performs a computation to detect the location and size of the defect. Therefore, the defect can be detected, at a high accuracy as the echo height is determined by varying the ultrasonic frequency.

Filed: 1986-05-29
Abstract: PURPOSE:To erase magnetization of a magnetic core and to prevent the degradation in electromagnetic conversion characteristic by subjecting the magnetic core joined with a fused glass to heat treatment in a rotating magnetic field. CONSTITUTION:A magnetic head 20 joined with a fused glass and formed by the grinding and polishing work or the like is placed on a turntable 2 in a chamber 1. A heating part 5 is operated to subject the magnetic head 20 to heat treatment in the rotating magnetic field while using gas introducing pipes 8 and 9 to substitute air in the chamber 1 with an inner gas like gaseous N2 and the magnetic field. In this heat treatment, annealing treatment having such temperature cycle is performed that the head is heated to a prescribed temperature and is kept at the prescribed time for a prescribed time and is cooled thereafter. The intensity of the magnetic field is gradually reduced in the cooling process of this annealing treatment. Thus, the degaussing action to erase magnetization of the magnetic head is performed and the work distortion is removed. As the result, the degradation in peak shift characteristic due to magnetization of the magnetic head 20 is prevented.
