IPC: H01L21/027
Filed: 1981-07-20
Abstract: PURPOSE:To improve accuracy of the pictured positions so much without increasing a time  necessary for picturing by an apparatus wherein a cassette is made homoiothermal at a given  temperature beforehand, a processing chamber, a preparatory chamber and the lower surface  of an object lens are respectively made homoiothermal, and stage temperature, cassette temperature within the preparatory chamber, cassette temperature within a thermostatic chamber  as well as the lower surface temperature of the object lens are controlled at a roughly equal  level. CONSTITUTION:Each cassette 7 within a preparatory chamber 2 is made homoiothermal beforehand using a thermostatic chamber 21 of a given temperature. Thermal radiation from the  lower surface of an object lens 19 is restricted with a constant-temperature water piping 22 and a constant-temperature water system 23. After storage in the thermostatic chamber 21, a  magazine 8 is placed with in the preparatory chamber 2 which is then vacuumed from the  atmospheric pressure. At this time, cassette temperature is lowered ca. 0.1 deg.C due to adiabatic  expansion. Then, the cassette 7 is transferred onto an X-Y stage 4 within a processing  chamber 1 and a mark pattern is pictured on a mask substrate 6. Temperatures of the X-Y  stage 4, the mask substrate 6, etc. are measured only one time when adjusting thereby to  attain temperature conditions for the constant-temperature water and the thermostatic  chamber 21 at which those temperatures become given ones. High pictured position accuracy of + or -0.1mum can be obtained just through temperature control based on such temperature conditions.

Title: Cassette lid opening/closing device
Inventor: AGARI HIDEO
IPC: G11B15/665
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To apply the action of a pack lid provided in a cassette so as to smoothly and surely load the cassette by erecting and fixing the rotary shaft of a second arm on a chassis base, engaging these together and pressing one of these by a spring. SOLUTION: The rotary shafts 11 and 13 of first and second arms 10 and 12 are erected and fixed on the base 9 of a chassis, and the projecting part 15 of the arm 12 is engaged with the long groove 14 of the arm 10. The arm 10 is pressed downward by a spring 16. When a cassette 1 is lowered, the arm 10 is rotated around the rotary shaft 11 counterclockwise by a pack lid 6. At this time, since the arm 10 is pressed by the spring 16, no large load is applied on the pack lid 6 and both are smoothly moved. When the loading of the cassette 1 is completed, the cassette 1 is brought into contact with the arm 12. Thus, since the arm 10 is greatly rotated clockwise, the arm 10 is moved away from the pack lid 6, no force for lifting the cassette 1 is applied and thus the cassette 1 is surely loaded.

Filed: 1993-04-16
Abstract: PURPOSE:To raise partial discharge start voltage by so constituting this device as to support a lead with an insulator stacked coaxially with a lead. CONSTITUTION:A lead support 3a and a lead presser 6a are both constituted by stacking insulators in the direction of surrounding a lead 5. And, the U-shaped lead support 3a supports the lead presser, and the top is attached to a pair of support metal fittings 2 fixed to a tank 1 by means of bolts 4. The lead presser 6a is semicircular long the lead 5, and above the lead 5, it is fixed to the lead support 3a by an insulating bolt 7. If it is done in the direction of surrounding the lead 5 in the stacking direction of the insulators of the lead pressers 6a, even if a thin air layer remains between layers, partial discharge does not occur in a low electric field since the air layer is in the direction vertical to the electric field of the lead 5. For this sake, the reliability can be improved without enlarging the dimension between the lead and the tank.
