Title: Exposure mask alignment method for semiconductor wafer
Inventor: MIYATAKE TSUTOMU
IPC: G03F9/00
Filed: 1998-03-02
Abstract: The method involves arranging a semiconductor wafer with an exposure surface to be illuminated, and an exposure mask, whereby a gap is formed between the exposure surface and the exposure mask. The wafer includes a mark formed on its exposure surface, which is provided with edges for the deviation of incident light. The exposure mask is provided with a mask mark located on its surface, with edges for the deviation of incident light. A relative position of the wafers and the exposure mask is detected by illuminating bent parts of the edges of the wafers and the mask, and observing of a light scattered by the bent parts in a direction with a slope with respect to the exposure surface.
