Patent JP-H06112172-A (JP)
Title: Dry etching
Inventor: KADOMURA SHINGO
IPC: H05H1/46
Filed: 1992-09-25
Abstract: PURPOSE:To smooth an etched surface in etch-back of a tungsten layer (Blk-W layer) formed by means of blanket CVD method. CONSTITUTION:In a first or an intermediate stage of an etch-back process of a Blk-W layer 5, a surface of the Blk-W layer 5 is smoothed by a deposit layer 6 obtained by discharge-dissociation of gas containing CSF2 (thiocarbonyl fluoride). This deposit layer 6 contains S (sulfur), carbon polymer containing S atoms, etc., and shows a high smoothing effect. By starting or continuing etch-back hereafter, coarse surface morphology of the Blk-W layer 5 may not be transferred onto an underlying surface of TiN barrier metal or an SiO2 layer insulating film 3. Depending on setting of etching conditions, smoothing by the CSF2 and etching can be simultaneously advanced. Also a loading effect can be suppressed.

Title: Heterogeneous reflection type refraction coupler laser array
Inventor: SHII CHIEN RII
IPC: H01S5/00
Filed: 1988-10-12
Abstract: PURPOSE: To generate a stable reference pattern by making the distribution of a waveform contour which is amplified in the center of a laser matrix with a maximum amplitude similar to the waveform contour of a reference pattern electric field. CONSTITUTION: An irregular reflection refracting coupler is added at the tail of a laser matrix, i.e., nearby a reflecting mirror and then it is led to a stabler reference pattern; when respective lasers in the laser matrix comes close to a mirror surface, they are all different in length and the center laser is the longest and closest to the mirror surface. The reflection of the laser field output sent by its waveguide terminal is intenser and less in loss, so that the advantage of easy oscillation are obtained. This reference pattern has its maximum amplitude at the center part of this laser matrix, and consequently the contour distribution of the amplified wave and the contour distribution of a reference pattern electric field wave are similar to each other. Consequently, the stable reference pattern can be generated.

IPC: B02C25/00
Filed: 1990-09-28
Abstract: PURPOSE:To contrive the automation of an operation of a litter pulverizer by providing a retention detecting means, a retention frequency deciding flag and a controller. CONSTITUTION:When this retention detector detects the retention of the litter, stops the detection and outputs a detecting signal to the retention frequency deciding flag 2 and the deciding flag 2 stores the number of times '1' and outputs the frequency signal into the controller 3. In the case of the frequency signal is inputted into the controller 3, a pushing-in device 4 is driven for definite time, then stopped and outputs a detecting reopening signal to the retention detector and the detection is reopened. In the retention detector 1, when the litter is stagnated at the time of the reopening of the detection of the retention of the litter, the retention frequency deciding flag 2 adds the number of times '1' and stores it. When the frequency signal inputted by the controller 3 from the retension frequency deciding flat 2 exceeds a prescribed value, the controller 3 activates not only the pushing-in device, but also to the alarming device and alarms the retention state of the litter to an operator. By this means, the operation of the pushing-in device is automatized and the reduction of a working load of the operator is attained.
