Title: Charged particle beam lithography and device therefor
Inventor: TANAKA SHOJI
IPC: H01L21/027
Filed: 1987-05-15
Abstract: PURPOSE:To secure a fail-safe action without stopping lithography by a method wherein, in case it becomes impossible for the formation of bit patterns to follow the feed of a stage, the lithography is once discontinued to perform the formation of bit patterns and the lithography is again continued. CONSTITUTION:Segments M1-M4 of a pattern memory 43 are used in rotation and a real time bit conversion lithography is executed. When the density of a drawing is increased and a bit conversion processing cannot follow the movement of a stage, a decision circuit 55 is actuated. That is, when a readout segment is changed over, an interruption is applied to a CPU by a timing error signal while a segment to be used next is still empty. When a plurality of masks are continuously being drawn, a mask, from which a timing error is generated, is aborted and the following mask is drawn. In short, the mask, from which a timing error is generated, becomes a defective without being recovered and the speed of the stage is slowed down afterword to come to be drawn.

Abstract: PURPOSE:To relieve the residents from unpleasant feeling due to direct hitting of an air flow against them at the time of periodic blow-off and enable to selectively air-condition either the entire part or a part of a room, by varying the range of blow-off direction in accordance with the speed of a room blower. CONSTITUTION:Room air sucked in through a suction port 4 is blown off through a blow-off port 5, and a vane 6 provided at the port 5 is periodically oscillated by periodic forward or reverse rotation of a stepping motor 8. The rotation of the motor 8 is so set that the vane 6 is periodically oscillated in the range of 6'-6'' at the time of high-speed operation of the blower 3, and is periodically oscillated in the range of 6''-6''' at the time of low-speed operation of the blower 3. As a result, in the case of the high-speed operation of the blower 3, conditioning air blown off from the air conditioner 1 is directed mainly into a region A outside the living space, so that it is prevented from directly impinging on the residents, and the interior of the room including a region B is uniformly air-conditioned under the function of the strong blow-off air flow. On the other hand, in the case of the low-speed operation of the blower 3, conditioning air is directed into the region B, so that the living space is mainly air-conditioned with a low air velocity.

Abstract: PURPOSE:To make output stable without fail regardless of any temperature fluctuation of detector by a method wherein a passivation film formed on a semiconductor photodetecting element is preliminarily made rough by etching process utilizing an active agent produced by plasma discharged from halogenide gas. CONSTITUTION:A multichannel type scintillator element 3 is bonded to a multichannel type photodiode 4 coated with passivation film 11 through the intermediary of a transparent adhesive 12 making each channel align with one another. The passivation film 11 mainly formed of silicon dioxide by vapor growing process to protect photodiode elements 6 is made rough by etching process utilizing an active agent produced by low temperature plasma of halogenide. Through these procedures, the adhesive 12 may be prevented from peeling off even under forcible thermal impulse since the bonded surface adhere firmly with each other due to the roughness of passivation film 11 regardless of the difference in the linear coefficient of expansion between the scintillation element 3, the photodiode element 6 and the transparent adhesive 12. Resultantly, any output may be made stable without fail.
