Title: Cleaning method of semiconductor device
Inventor: INAGAKI NAOKI
IPC: H01L21/304
Filed: 1991-04-26
Abstract: PURPOSE:To increase the withstand voltage of a thermal oxide film and improve the yield of a semiconductor device, by eliminating heavy metal which has permeated into a semiconductor substrate, and forming a clean and flat semiconductor surface. CONSTITUTION:An oxide film 2 of about 30Angstrom  in thickness is formed by dipping a semiconductor substrate 1 in 30% hydrogen peroxide solution at 60 deg.C for 3 minutes. Heavy metal elements 3 in the semiconductor substrate 1 are taken in the oxide film 2. The heavy melal 3 is subjected to wet etching together with the oxide film 2 on the semiconductor substrate 1 surface by using dilute hydrofluoric acid. Thus a clean and flat surface of the semiconductor substrate 1 is obtained.

Title: Retrial control method at the time of detecting cell full
Inventor: TANAKA HIDEHIKO
IPC: G11B15/68
Filed: 1989-04-17
Abstract: PURPOSE:To analyze a fault more accurately by retrying a detection result with the use of a robot when the cell full is detected. CONSTITUTION:When the cell full is detected, a detection result is once reserved to a reserve cell, the robot is switched to another robot 7, and the retrial is executed. As the result of the retrial by switching the robot, when a process is normally completed, it is judged that a previously used robot 6 has a hardware trouble. As the result of the retial by switching the robots 6 and 7, when the process is not normally completed, a cartridge magnetic tape is positioned on the reserve cell again, a selecting/restoring process is executed before a target cell. Consequently the cell-full can be discriminated from cell block abnormality. Thus the fault can be highly accurately analyzed.

Title: Strip antenna and entering/leaving information input device using the same
Inventor: ASAKURA KENTARO
IPC: H04B1/59
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To provide an antenna which is suitable for reception and further made compact and light in weight so as to be hardly conspicuous. SOLUTION: This strip antenna 10 is formed by laminating a conductor layer 12, dielectric layer 14 and conductor layer 16. The respective layers of the strip antenna 10 are mutually fixed by adhesive gents of the like. The size, thickness and material for each layer of the strip antenna 10 are designed corresponding to the required characteristics. Since the strip antenna 10 has the sufficient size, it can be appropriately used as an antenna for reception. Further, since this antenna is not protruded differentially from a dipole antenna, not only it is not conspicuous but also beautiful appearance can be improved. Further, since this antenna is extremely light in weight and formed in the shape of slender plate in comparison with the dipole antenna, the antenna can be easily and strongly attached even with bouble coated tapes or the like.
