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： 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： A method of exposing a wafer to exposure energy such as ultraviolet rays or X-rays through a mask to transfer a pattern of the mask onto the wafer, for example. The temperature of the mask and/or the wafer increases during the exposure operation by absorption of the exposure energy. While the wafer is being exposed, the temperature of the mask and/or the wafer is detected. If the temperature is going to exceed an exposable temperature range determined on the basis of the line width of the pattern to be transferred, the exposure operation is interrupted. Then, the heat accumulated in the mask and/or the wafer is removed. Thereafter, the exposure operation is resumed. This is repeated until the predetermined or required amount of exposure is reached, for one shot. By this, thermal expansion of the mask and the wafer during the exposure operation is prevented to assure the precision of the pattern transfer.

摘要： A temperature controlling device suitably usable in a semiconductor microcircuit manufacturing exposure apparatus exposes a semiconductor wafer to a mask to print a pattern of the mask on the wafer. The device includes a constant-temperature liquid medium supplying system for controlling temperature of a liquid at high precision, a distributing system for distributing the supplied liquid medium into plural flow passages, to supply the liquid medium to plural subjects of control such as, for example, a mask stage, a wafer stage and the like.
