Latest Patents

Tsukamoto holds a patent for a semiconductor device manufacturing method. This method involves cutting work performed on an n-semiconductor substrate using an inverted trapezoid-shaped dicing blade. The process forms grooves that serve as second side walls. The bottom portions of these grooves contact a p-diffusion layer formed on the front face of the n-semiconductor substrate, ensuring that the p-diffusion layer remains uncut. Consequently, a p-isolation layer connected to a p-collector layer and the p-diffusion layer is formed in the second side walls. This innovative method eliminates the need for a glass support substrate and expensive adhesive, allowing for the p-isolation layer to be formed at a lower cost.
