Title: Mask for exposure use and exposure
Inventor: YASUI JURO
IPC: G03F1/68
Filed: 1988-06-09
Abstract: PURPOSE:To align semiconductor devices of arbitrary chip sizes with high accuracy and to expose them to X rays by a method wherein two or more alignment regions are formed in positions limited by positions of an alignment optical system. CONSTITUTION:Inside a limited maximum exposure region M, a prescribed position near two adjacent boundaries of the maximum exposure region M and a pattern exposure region P where a semiconductor device pattern to be transcribed has been formed is exposed by using an X-ray mask 5 having an alignment region where a mask mark 7 has been formed. In this manner, the mask mark 7 inside the alignment region decided independently of a position of the pattern exposure region P is used for an alignment operation of the X-ray mask 5 with a semiconductor substrate 1 ; accordingly, a size of the pattern exposure region P, i.e. a size of a semiconductor device, is not restricted. In addition, since the pattern exposure region P is situated near a boundary of the maximum exposure region M, a substrate mark inside a semiconductor device chip formed on the semiconductor substrate is formed in a peripheral part of the chip. Thereby, it is possible to manufacture semiconductor devices of different sizes without spoiling an advantage of an X-ray exposure.
