Patent JP-S56146303-A (JP)
Title: Transmission line
Inventor: TAKEDA AKIHISA
IPC: H01P3/08
Filed: 1980-04-15
Abstract: PURPOSE:To facilitate an easy production of transmission lines even with a high characteristic impedance, by distributing a transmission conductor at the position to which no earth conductor is opposite. CONSTITUTION:The earth conductor 2 and transmission conductor 4 are adhered in parallel onto both surfaces of the dielectric substrate 1. The conductor 4 is not opposite to the conductor 2. In general, the characteristic impedance Z0 of the transmission line is expressed as Z0=(L/C)   where L is the line inductance per unit length and C is the interline capacity C. In this example, a wide gap can be secured between the conductor 4 and conductor 2. As a result, the capacity C can be reduced, which results in obtaining a high characteristic impedance with a transmission conductor having a comparatively large width.

Title: Wire bonding device
Inventor: MATSUMOTO ITARU
IPC: H01L21/60
Filed: 1990-03-02
Abstract: PURPOSE:To obtain a stable bonding by a method wherein when a positional error between a targeted orbit and a capillary exceeds a certain value after the capillary is changed-over, contact of the capillary with a bonding pad is detected. CONSTITUTION:When a capillary 3 comes into contact with a pellet 9, a positional error between the capillary 3 and a targeted orbit is gradually increased. Accordingly, after an elapse of a constant time, an error larger than an error to become a threshold error is detected 15. Thereby, it is detected 15 that the capillary 3 comes into contact to the pellet 9. A change-over circuit 13 selects a signal from a pressure command circuit 12 by this error detection signal, a constant current is applied to a moving coil 4 and a constant pressure is applied. Moreover, the threshold error is selected in such a way that an applying pressure due to the threshold error becomes smaller than the bonding pressure. Thereby, a bonding becomes possible without applying an excessive applying pressure to the pellet 9.

Abstract: PURPOSE:To enable the etching in a uniform depth with reduced deposit of readhered material, by repeating a plurality of times of operation to etch a shallow groove by surface scanning a region to be etched with a converging ion beam having a low irradiation density. CONSTITUTION:A shallow etching groove is formed with a forcusing ion beam having a lower irradiation density than the density of a converging ion beam able to etch a groove with a required depth. For this purpose, linear scanning is performed with the converging ion beam 5 in the direction as indicated by an arrow (s) in 50 sweeps for example successively deviated in the direction indicated by a broken-line arrow (p) to finish scanning of one surface, so that an etching groove 6a is obtained. 7a is a deposit layer of material readhered during the scanning. This surface scanning is performed in a multiplicity of times so as to obtain etching grooves 6b and 6c. Deposit layers of material readhered in these stages are reduced remarkably as shown by 7b and 7c, and thus etching in a uniform depth is enabled.
