Latest Patents

One of his latest patents is a wafer processing apparatus. This apparatus includes an X-θ stage unit with a rotary chuck that can move in an X direction and rotate in a θ direction. A wafer is mounted on the rotary chuck, which features an edge portion adjacent to the wafer's edge. Additionally, the apparatus includes an edge bead removal (EBR) measurement and eccentricity measurement unit. This unit inspects the bead removal state of the wafer's edge portion and measures the eccentricity between the centers of the rotary chuck and the wafer. Furthermore, it has an edge exposure of wafer (EEW) process unit that exposes the wafer's edge portion after correcting the eccentricity.

Another significant patent involves a semiconductor device manufacturing system, which includes a spin coater and a coating layer inspector. The spin coater consists of a chuck, a rotation driver to rotate the chuck, and a solution dispenser that sprays a solution onto the coating layer formed on the wafer's edge portion. The coating layer inspector features an edge inspection camera and an inspection controller that determines the radius, eccentricity, and top-view shape of the coating layer based on images of the wafer's edge.
