Latest Patents

Yoshito Nakase holds a patent for a "Method for forming scribed groove and scribing apparatus." This method involves forming scribed grooves on a wafer using a cutting part that moves in an inverted trapezoid-shaped path. This innovative approach reduces the scribing angle of the cutting edge to an acute angle, allowing for better dispersion of mechanical shock stress during the scribing process. The horizontal movement of the cutting edge enables the application of sufficient load perpendicular to the scribing plane, resulting in the generation of vertical cracks and minimizing dimensional deviation between the scribed groove and the cleaved plane. This method ultimately produces chips with higher precision and high-quality mirror finish on cleaved surfaces.
