IPC: H01L21/66
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To evaluate the electrical characteristics through bending stress at a wafer level, by vertically moving the wafer receiver of a vacuum chucking mechanism which chucks the wafer with the vacuum. SOLUTION: A wafer 9 is placed at the end surface of the spot facing part in a space 2 in advance, so that the outer surface of the wafer is overlapped when observed from the upper part. Then, after the back surface of the wafer 9 is chucked to the vacuum chuck 2 by a vacuum chuck driver 7, a guide 8 is held so as to be aligned with the base end surface. The wafer 9 can be bent up or down by moving the vacuum chuck 2 in the vertical directions in this state. That is to say, the status, wherein the tensile stress or compressive stress is applied, can be formed artificially for the wafer 9. Thus, the evaluation and the measurement of the electrical characteristics of the semiconductor element formed on the semiconductor wafer 9 can be performed.

Title: Method for initializing optical recording medium and initialization assistance layer
Inventor: KOJIMA HIDEKI
IPC: G11B7/0055
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To enable even the initialization of an optical recording medium, the initialization of which is heretofore not possible with existing initialization devices on account of excessively high or low laser beam reflectivity by mounting an initialization assistance layer to the later beam incident side of the optical recording medium, thereby changing the laser beam reflectivity when the optical recording medium is initialized by irradiation with the laser beam. SOLUTION: The optical recording medium formed with a recording layer, dielectric layer and reflection layer by a high-frequency sputtering method on a polycarbonate substrate with spiral grooves of 0.6 mm in thickness and 12 cm in diameter. The polycarbonate resin substrate with the transparent spiral grooves of 0.2 to 0.8 mm in thickness (0.6 mm in this embodiment) and 12 cm diameter is mounted as the initialization assistance layer on the laser beam incident side of the initialized disk. As a result, the optical recording medium of 4 to 40% in reflectivity and 1.2 mm in total thickness is initialized by irradiating the recording medium with the semiconductor laser beam from the initialization assistance layer side by using the existing initialization device. As a result, the initialization with the existing initialization device is made possible.

Title: Magnetic sensor
Inventor: SEKINE YUKIO
IPC: H01L43/08
Filed: 1985-06-14
Abstract: PURPOSE:To enable high identification by forming a raster on only one of a pair of magnetoresistance elements, and preventing the cancelling of outputs when character patterns having equal interval and width to those of the elements are continuously arrived. CONSTITUTION:A raster 5 is formed on only one magnetoresistance element 3 of a magnetic sensor 1 having a pair of magnetoresistance elements 3, 4 secured onto a substrate 2. Here, the raster 5 is mounted in a stripe shape perpendicularly to the longitudinal direction onn the slender substrate 2, the element 3 is equivalent to the series connected magnetoresistance elements having shorter distance between electrodes than the width of the electrodes, thereby increasing the resistance value. The elements 3, 4 are formed on the same substrate, differentially connected to compensate the temperature to one another. Only the element 3 is largely varied in the resistance by forming the raster 5, but the element 4 is not almost altered. Thus, even if equal character pattern are continuously arrived to the width and the interval of the elements, the output can be detected without cancelling each other out.
