Latest Patents

One of Sano's latest patents is a charged particle beam exposure apparatus. This invention involves changing the dimensions of the cross-section of an electron beam emitted from a beam source using deflectors. These deflectors are positioned between a pair of aperture masks and are corrected by beam position correction deflectors. The electron beam is then irradiated onto a wafer, with correction signals supplied by a correction signal generating circuit based on beam dimension signals from a CPU.

Another notable patent is a method of forming an integrated circuit pattern on a semiconductor wafer. This method involves projecting a plurality of reference marks onto a second semiconductor wafer using radiant rays from a projector apparatus. The positions of these reference marks are measured to assess the projection distortion specific to the projector apparatus. Subsequently, a projection mask is produced to offset the projector's distortion, allowing for accurate pattern formation on the first semiconductor wafer.
