Title: Developer used for photolithography
Inventor: SATOU SHINJI
IPC: H01L21/027
Filed: 1981-08-12
Abstract: PURPOSE:To prevent the developer to penetrate into the rear side of wafer by providing a ring-shaped cover having plurality of air blasting holes to the cup and the air supply route connected to said holes are provided within said cup. CONSTITUTION:The apertures 14, 15 which allow engagement of wafer fitting chuck are formed at the bottom and cover 13 of the cup 12 and the cover 14 is provided with plurality of air injection holes 16, 19. The air supply route 19 is provided within the vacuum chuck 17 separately from the absorbing route 18 and this air supply route 19 is opening to the inside of cup 11. On the occasion of developing latent image transferred to the photo resist on the wafer surface, the wafer 20 is absorbed and fixed to the wafer fitting surface of the vacuum chuck 17 by means of the vacuum absorbing through the absorbing route 18. The air sent to the cup 11 is blasted from the air blasting hole 16 provided at the cover 13, causing the air to flow into outer side of radius direction along the rear side of wafer. Therefore, this air flow prevents the sprayed developer to penetrate into the rear side of wafer 20 and to be adhered thereto.

It also opens a gate S 1  or S 2 , and a constant voltage is fed back according to the output through an amplifier A 3 . The feedback circuit works as a circuit of time lag of first order when an amplifier A 2  is saturated, and works as an integrator when unsatureted. A circuit composed of amplifiers A 4  and A 5  gives a short-circuit to a resistance R 6  when the absolute value of the feedback output is under a fixed level for increasing the gain of the feedback circuit. Consequently, the object to be controlled is given an output to kill offset by the integral operation of the offset.

Filed: 1985-06-13
Abstract: PURPOSE:To enhance working efficiency while eliminating the fatigue of an inspector, by always stabilizing the incident angle of light incident to a recording medium to detect the grooves of the medium. CONSTITUTION:A condensing means 46 is fixed to a detection means 52 at a predetermined angle by a fixing member 48. The lens 56 generated from a halogen lamp 44 is condensed by a condensing lens 46 to irradiate a medium 12. The reflectivity is different between the groove region 18 and flat surface region 19 on the medium 12 and only the light 57a allowed to irradiate the grooves 16 of the region and reflected therefrom is incident to a high magnification lens cylinder 50 and detected by an image sensor 52 and the detection result is further projected on the picture 55 of a monitor TV54 and, therefore, the detection of the grooves 16 can be performed with high accuracy. The lens 46 always stabilizes the incident angle of light 56a. Because, the detection of the grooves 16 is performed by the monitor TV54, long-time adjustment becomes unnecessary and, further, even if long-time detection is performed, an inspector does not become fatigued.
