Title: Tsutomu Maeda: Innovator in Laser Processing Technology
Introduction
Tsutomu Maeda is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of laser processing technology, holding a total of 11 patents. His innovative work has advanced the capabilities of laser processing apparatuses, making them more efficient and effective.
Latest Patents
One of Maeda's latest patents is a laser processing apparatus that features a control unit with an inspection modified layer former. This unit detects a provisional orientation flat of a bare wafer and applies a laser beam of predetermined output power to the wafer based on the orientation flat's direction. This process helps in forming a modified layer that closely detects the crystal orientation near the wafer's outer edge. Additionally, the apparatus includes a crack detector that identifies any cracks extending from the modified layer toward the Y-axis and the exposed surface of the wafer. If no cracks are detected, the control unit confirms that the modified layer is parallel to the wafer's crystal orientation.
Another notable patent involves a controller for a laser processing apparatus that includes a storage section for processing conditions related to forming modified layers along division lines of a wafer. The processing line calculation section displays the planned position for the modified layer on a display panel, ensuring that the start or end points of modified layers do not interfere with each other.
