Latest Patents

One of his latest patents is the "Apparatus for scribing semiconductor wafer with laser beam." This apparatus is designed to scribe a semiconductor wafer using a laser beam in a single direction along an axis. It features an XY table for wafer placement, a laser beam oscillator positioned above the table, and an optical system that directs the laser beam onto the wafer. The apparatus includes a light interrupting switch that allows the laser beam to pass only when the XY table moves in the designated direction, ensuring precision in the scribing process.

Another significant patent is the "SOS Substrate for semiconductor device." This invention provides an SOS substrate where an epitaxial silicon layer with a (100) plane index is formed on a single crystal sapphire plate with a (1012) plane index. An orientation flat is created at an incline angle of 2.1 to 2.2 degrees concerning the [011] direction on the epitaxial silicon layer. The orientation flat on the sapphire plate aligns with the cleavage plane of the sapphire, enhancing the substrate's performance.
