摘要: The present invention relates to a temperature control system for a lithographic exposure apparatus wherein a mask and wafer are closely disposed, and predetermined exposure energy is applied to respective shot areas of the wafer through the mask. The exposure energy is a soft-X-ray source, for example. The pattern of the mask is transferred onto the respective shot areas in a step-and-repeat manner. In the apparatus, a temperature control medium liquid is supplied into the wafer chuck which supports the wafer at the exposure position. The flow rate of the temperature control liquid is different during an exposure operation than during a non-exposure-operation. The flow control is determined in consideration of the wafer chuck vibration attributable to the supply of the liquid medium and also, of the heat generation in the wafer by the exposure energy, so that the vibration of the wafer chuck during the exposure operation is suppressed. Simultaneously the temperature rise of the wafer can also be suppressed. The pattern transfer from the mask to the wafer thus be precisely performed.

摘要: An exposure apparatus usable with synchrotron radiation source wherein the synchrotron radiation is generated by electron injection into a ring. The exposure apparatus is to transfer a semiconductor element pattern of a mask onto a semiconductor wafer by the synchrotron radiation. The apparatus includes a shutter for controlling the exposure of the wafer. The shutter controls the exposure with the illuminance distribution on the wafer surface taken into account. The illuminance distribution is determined in response to the electron injection, and thereafter, the illuminance distribution is corrected in a predetermined manner. By this, the illuminance distribution data for controlling the shutter always correspond to the actual illuminance distribution. The entire shot areas of the semiconductor wafer are exposed with high precision.

摘要: A wafer chuck usable with a semiconductor exposure apparatus wherein a mask and a semiconductor wafer are placed in a vacuum ambience or a pressure-reduced gas ambience, and wherein the wafer is exposed through the mask to radiation energy such as X-rays contained in a synchrotron radiation beam, by which the pattern of the mask is transferred onto the wafer. The wafer is first attracted on the wafer supporting surface of the chuck by vacuum attraction, and thereafter, the wafer is attracted by the electrostatic attraction force. Thereafter, the vacuum attraction is broken by supplying a gas. When the pattern of the mask is transferred onto the wafer, the wafer is retained on the wafer supporting surface by the electrostatic attraction force only. By this, the sheet-like member (wafer) supporting apparatus can correctly contact the wafer supporting surface to the wafer without being influenced by the undulation of the wafer. In addition, the heat produced in the wafer during exposure can be removed efficiently by temperature controlled water supplied to the wafer supporting apparatus.

摘要: An apparatus for transferring a pattern of a mask onto a substrate with radiation light from a synchrotron radiation light source, includes a first mirror for collectively reflecting radiation light from the synchrotron radiation light source, and a second mirror for reflecting radiation light from the first mirror and for projecting the same to the mask. When a light ray advancing from a light emission point of the light source toward a center of a predetermined region of the mask, to be transferred to the substrate, is taken as a chief ray, when a normal to each of the first and second mirrors at an incidence position of a corresponding chief ray is taken as a Z axis, when a direction perpendicular to a plane defined by the Z axis of each mirror and a corresponding chief ray is taken as an X axis, and when a Y axis is taken along a direction perpendicular to the Z axis and X axis of each mirror, the first mirror has a reflection surface of a shape which is concave with respect to the X axis direction and concave with respect to the Y axis direction, while the second mirror has a reflection surface of a shape which is convex with respect to the Y axis direction.
