Abstract: PURPOSE:To elongate the life of a crystal and stabilize the output of a laser beam, and improve the quality of a beam by providing an EO crystal in a constant-temperature vessel which has a laser beam transmitting window. CONSTITUTION:A constant-temperature vessel 10, which has an EO crystal 1 within and has a laser beam transmitting window 50a, is provided, and a heating coil 53 for heating the EO crystal 1 and a medium 51 is provided in the constant-temperature vessel 50. The EO crystal 1 is controlled for temperature within the constant-temperature vessel 50. The light damage of the EO crystal 1 can be reduced by keeping the stability of temperature not more than + or -5 deg.C, preferably, + or -1 deg.C, within the range of 50-250 deg.C, preferably, 150-200 deg.C in temperature of the medium 51, thus a laser beam 45 stable for a long term and excellent in beam quality can be gotten. In the condition that the temperature of this medium 51 is lower than 50 deg.C, the reduction of the light damage can not be achieved. Moreover, in the condition that the temperature is 250 deg.C, the occurrence of the impurities from the heating coil 53, etc., becomes active in the medium 51, it is necessary to control it to 250 deg.C or less.

Title: Electron beam exposure
Inventor: OKINO TERUAKI
IPC: H01L21/027
Filed: 1980-10-24
Abstract: PURPOSE:To cancell a change of a pattern size caused by an apparent sensitivity change due to a shelf time in vacuum by a method wherein the pattern size written by an electron beam is changed in accordance with the shelf time in vacuum. CONSTITUTION:An apparent sensitivity changes in accordance with a shelf time as shown in the figure. By this change a pattern size S written on a material changes in accordance with the shelf time in vacuum as shown by a solid line in figure in spite of that a pattern area of a definite size S0 is exposed. This size can be expressed as a function of the shelf time in vacuum t S=f(t). Then the pattern size written by an electron beam is changed along a function S=f'(t) which is shown by a dashed line and is symmetrical with respect to S=S0 (constant). With above method this change cancels cross-linking reaction as a result, so that, when a substrate exposed for, for instance, 40min is taken out of vacuum, both the size of the pattern exposed at first and that of the pattern exposed in the end can be of specified value  S0.

Abstract: PURPOSE:To realize a small size and l low cost of the device by using the space of a charging unit as the optical path of an eraser. CONSTITUTION:A shutter 22 is driven from a shield position shown in the solid line in the figure, to a refuge position shown in the two-dot chain line where it is rotated about 60rt. angle counterclockwise. When the shutter 22 is at the refuge position, a part of the beams emitted by a power removing lamp 10 enters to the inner space of a charging unit 1 through an opening 21, it hits to and is reflected by the inner surface of the casing of the charging unit 1 having a high reflectivity, and then it hits the surface of a sensitizer drum 11 opposing to the inner space of the charging unit 1. Even though the charging unit 1 is ON, and the surface of the sensitizer drum 11 is charged by a corona discharge wire, the charge is removed by the beams passing through the opening 21. That is, the means 10 and 21 to 23 radiate the beams to remove the charge to the sensitizer drum 11 through the inner space of the charging unit 1. Since the space of the charging unit 1 is used as the optical path of an eraser in such a way, an exclusive optical path for the eraser as in the conventional device is not necessary to prepare.
