Title: Plane antenna used in common for two frequencies
Inventor: NAKAJO WATARU
IPC: H01Q5/10
Filed: 1991-12-24
Abstract: PURPOSE:To obtain large isolation between two antennas having a different resonance frequency by providing two plane antennas to the system in a way that they are parted by a desired interval and they are rotated by a prescribed angle. CONSTITUTION:First and 2nd circular patch antennas have respectively radiation conductors 41, 42 of circular patch shape whose diameter differs from each other. Thus, the resonance frequency of them differs from each other and the antennas are used at different frequencies. The 1st circular patch antenna is formed by being rotated relatively by a relative angle thetap clockwise with respect to the 2nd circular patch antenna. The electrical mutual coupling, that is, the isolation between the 1st and 2nd circular patch antennas is changed. Thus, the better isolation is obtained by adjusting the relative angle thetap so as to increase the isolation.

Title: Manufacture of semiconductor device
Inventor: YAMAKAWA HIROSHI
IPC: H01L29/49
Filed: 1990-11-30
Abstract: PURPOSE:To increase the workability of gate electrodes by inserting high melting point metal between layers of polysilicon and silicide which constitute gate electrodes, and by facilitating the detection of etching end points of the layers of the silicide and high melting point metal. CONSTITUTION:After the formation of field oxide films 2 on a semiconductor substrate 1, polysilicon 5 is deposited, and high melting point metal 4 and silicide 3 are deposited. After this, etching is performed using photoresist 6 as a mask. When the high melting point metal 4 becomes in a state of being etched after the etching completion of the silicide 3, luminous intensity decreases as the SiF density in plasma decreases. On this occasion, the end point of the etching of the silicide 3 can be easily detected as the end point detection of the etching of the silicide 3 and high melting point metal 4 is done by setting and measuring the luminous intensity of a specific wavelength by SiF which increases by the etching of the polysilicon 5. Accordingly, the workability of the gate electrodes increases.
