Latest Patents

One of his latest patents is a method of forming and cleaning a laser marking region at a round zone. This invention relates to a wafer used as a substrate for semiconductor devices. The wafer features a round zone along its circumference and a flat zone with a partially cut circumference. A laser marking region, functioning as a wafer bar-code, is formed in the upper portion of the round zone. This bar-code includes holes approximately 2 micrometers deep, created through a soft marking process. The invention allows for the formation of fine patterns on the wafer while effectively cleaning photoresist materials from the laser marking region, thereby reducing the occurrence of G-defects caused by residual particles.

Another significant patent by Kim is a reticle for fabricating semiconductor devices. This reticle includes alignment marks designed to examine pattern mistakes, formed upon a scribe line. The alignment marks consist of pairs of adjoining primary and secondary measurement patterns. Each primary measurement pattern features a rectangular design on a rectangular plate, complemented by a rod-shaped pattern along its sides. The secondary measurement pattern is designed to fit into the primary pattern, allowing for precise examination of their relative positions.
