Latest Patents

Kazuki Okabe holds a patent for an evaluation method of silicon wafers. This method allows for non-destructive and non-contact inspection of slips that can affect the electrical properties of semiconductor devices. It operates without being subjected to the restrictions of the surface condition of silicon wafers or processing contents. The evaluation method includes a section analysis step, where the surface of a single crystal silicon wafer is divided into sections. The existence of strain in each section is determined based on the depolarization value of polarized infrared light. Additionally, a screening step evaluates the wafer as non-defective when the number of adjacent sections determined to have strain does not exceed a predetermined threshold value.
