Title:
EXPOSURE METHOD AND EXPOSURE DEVICE
Document Type and Number:
Japanese Patent JP2008091793
Kind Code:
A
Abstract:
To provide an exposure method and an exposure device, capable of locally optimizing such factors as incident angle, polarizing direction, and exposure amount, according to places in a sample when patterning the solid sample having a rough on its surface.
When a solid sample 1 having a rough on its surface is subjected to a lithography processing, the incident light 2 is inclined within the range of 10 to 60 relative to the normal direction of a substrate surface of the solid sample 1 for exposure, in an exposure process in which a resist is applied for patterning. Here, the amount of exposure may be varied partially depending on the place in the solid sample 1. The incident light 2 whose polarizing direction 4 is controlled may be used.
