    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. The device further includes a plurality of temperature controls each being provided in corresponding one of the flow passages, for correction of any variance in temperature of the distributed liquid medium, resulting from pressure loss energies in the respective flow passages. Thus, temperatures of plural subjects of control can be controlled efficiently and with a simple structure.

    摘要: A substrate conveying apparatus usable with a semiconductor manufacturing apparatus wherein a pattern of a mask is transferred onto a semiconductor wafer by exposing the semiconductor wafer to synchrotron orbital radiation or other exposure energy through a mask. The conveying apparatus transfers the semiconductor wafer to and from a wafer chuck while the surface thereof extends vertically, and/or transfers the wafer to and from a wafer cassette which contains a plurality of wafers horizontally. The apparatus includes a conveying hand having a gimbal mechanism for supporting the semiconductor wafer to assure the semiconductor wafer transfer to and from the wafer chuck while the wafer is vertical. When the semiconductor wafer is transferred to and from a wafer cassette, the apparatus is provided with a correcting mechanism for correcting the attitude of the conveying hand to prevent the semiconductor wafer from contacting the wafer cassette.
