Title: Deflector
Inventor: TAKITA HIDENORI
IPC: H01J29/76
Filed: 1985-09-28
Abstract: PURPOSE:To produce a low-cost deflector without reducing the sensitivity of vertical deflection by using four front magnetic pieces and two back magnetic pieces as members for correcting the front distribution of a vertically deflecting magnetic field into a pin-cushion from and the back distribution into a barrel form and locating these members between the vertically deflecting coil and the horizontally deflecting coil. CONSTITUTION:Front correction members consist of four magnetic pieces 5c-5f. The front magnetic pieces 5c-5f and back magnetic pieces 56a and 6b are affixed to given positions on the outer surface of a separator 3. The magnetic pieces 5c-5f produce a front vertically deflecting magnetic field 10F with a pin-cushion form. A vertically deflecting magnetic field 10 consists of the front region with a pin-cushion form and a back region with a sharp barrel form. It is distributed in a barrel form as a whole. Due to the above structure, the self convergence of this deflector and its pin-cushion distortions on the right and the left of the raster are alleviated. Furthermore, the cost of the magnetic pieces 5c-5f is low because they are small and have a simple shape. Besides, the magnetic pieces 5c-5f minimally reduce the deflection efficiency of a vertically deflecting coil 2.

Abstract: PURPOSE:To enable pattern transfer always at a predetermined reduction ratio by providing a temperature controller in the wafer stage, and controlling the wafer temperature according to the fluctuation of the reduction rate of a projection aligner, thereby offsetting the fluctuation of the reduction ratio with the thermal expansion and thermal shrinkage of the wafer. CONSTITUTION:A mask M is illuminated by a light source 11 and a condenser lens 12, and a mask pattern is projected and exposed on the surface of a wafer W by an imaging lens 13. And, the atmospheric pressure at this time is measured by a barometer 32, and in a microcomputer 31, the fluctuation of the reduction ratio at this atmospheric pressure is calculated from the characteristics of the atmospheric pressure and the reduction ratio. Further, this reduction ratio is applied to the thermal expansion coefficient of the silicon wafer to calculate a wafer size needed for correcting this fluctuation. And this calculation result is outputted to a heater controller 24 or a flow rate control valve 26 in order to control the electrical energization amount of a heater 23 or the cooling medium flow rate of a cooling pipe 25 based on the measured temperature of a thermocouple 27, thereby heating or cooling the wafer W to a required temperature through a base stand 21. For this, the wafer W is thermally expanded or thermally shrinked in response to the reduction rate. Therefore, a pattern transfer with a stable reduction rate can be achieved.
