Title: Antenna performance measurement device and antenna performance measurement method
Inventor: SHIMAWAKI YUTAKA
IPC: G01R29/10
Filed: 1993-04-19
Abstract: PURPOSE:To install a collimation antenna at a near distance by driving a sub reflecting mirror so as to correct a phase deviation due to the path difference between a center and an end of a main reflecting mirror for a radio wave from the collimation antenna. CONSTITUTION:When the distance R between an antenna system 1 and a collimation antenna 2 is small, wave fronts 3a, 3b, 3c of a radio wave from the antenna 2 have a path difference DELTAR between a center and an end of a main reflecting mirror 11 to cause A phase difference. On the other hand, radio wave optical path lengths FP1A1, FQ1G1B1 and FR1H1C1 from the system 1 are constant. In order to eliminate the path difference DELTAR, a sub reflecting mirror drive mechanism 13 equipped to the sub reflecting mirror 12 of the system 1 drives the sub reflecting mirror 12 up to a position 12a by DELTAZ apart from the main reflecting mirror 11. As a result, an equi-phase face OC1B1A1 of a radio wave on the aperture of the main reflecting mirror 11 is changed on a circular ark like an arc face OC2B2A2 and the DELTAR is decreased to approach the wave front 3a of the radio wave from the antenna 2. Thus, the sub reflecting mirror 12 has only to be driven so that the arc face OC2B2A2 most approaches the wave front 3a.

Abstract: PURPOSE:To effectively analyze impurities on a rough wafer surface with a simple apparatus by sealing a semiconductor wafer and chemical solution in a synthetic resin bag to be soaked in warm water, having the wafer and the chemical solution reacted with each other and analyzing the reaction solution. CONSTITUTION:After a polypropylene bag is cleaned in ultrapure water, chemical solution same as that used for reaction, for example hydrofluoric acid, nitric acid, hydrochloric acid or the like is sealed in the bag, the bag is put into a water bath maintained at 80 deg.C, and impurities which could not be completely removed by ultrapure water are solved. After the solution is discharged, it is sufficiently cleaned again in ultrapure water, a semiconductor wafer 2 and chemical solution 3 are put into the cleaned bag 1, the bag is sealed and then soaked in the water bath of 80 deg.C. A weight is attached to the bag 1 to prevent it from floating, after the bag is pulled out 180 minutes later and slowly cooled to a room temperature, reaction solution is collected to prepare measuring sample, and elements are analyzed by an atomic absorption meter. Thus drop in viscosity in rise in water pressure and temperature contributes to facilitate penetration of the chemical solution into uneven parts of a wafer surface in addition to heating processing of the wafer and the solution 3 in a contact state.

Title: Method for depositing thin aluminum film
Inventor: SASAOKA CHIAKI
IPC: C23C16/20
Filed: 1988-05-10
Abstract: PURPOSE:To grow a thin Al film having a low concn. of carbon at a low temp. by using an organometallic compd. having one or two Al-Cl bonds in the molecule as starting material in vapor growth of Al with an organometallic compd. CONSTITUTION:When a thin Al film is deposited by a vapor growth method with an organometallic compd., an organometallic compd. having one or two Al-Cl bonds in the molecule is used as starting material. This compd. is converted into Al chloride by thermal decomposition and Al is produced from the Al chloride by a disproportionation reaction. Since this reaction does not take place in the presence of an added org. group, the resulting Al film is hardly contaminated by carbon. In the case where diethylaluminum chloride is used as the organometallic compd., the growth temp. can be reduced and selective growth can be carried out.
