Title: X-ray exposure system and device
Inventor: IWAMATSU SEIICHI
IPC: G03F1/22
Filed: 1979-02-23
Abstract: PURPOSE: To operate high-precision positioning and simplify exposure by a method wherein a mask and a wafer are fixed at a distance between them and in parallel to each other, while each one is exposed to independent incident light, positioning signal is obtained from their surfaces, and after they are positioned, they are exposed to X-rays.  
     CONSTITUTION: Wafer 11 is exposed to X-rays 15 of high directivity like those of a synchrotron, via mask 12 having gold mask pattern 17. At this time, since the directivity is good, the precision in pattern transfer is not lowered even if the distance between mask 12 and wafer 11 is set at several cm, and mask 12 and wafer 11 can be exposed to independent visible incident light 19 and 18, and at the same time they can produce independent reflected light. Photo pattern signal (positioning signal) well-matched with each pattern is detected (20), and thereby the positional realtion between mask and wafer can be controlled and accurate positioning can be operated. By this system, as the base body of mask 12, material which is optically non-transparent but has good X-ray transmissivity, such as C, can be used, so that a low-cost device can be obtained. Further, since the X-ray source can be placed above the center of the mask, accurate positioning can be operated and the exposure is simplified.
