Latest Patents

Kei Tanaka holds 1 patent for his invention titled "Manufacturing method of device chip." This patent describes a process that includes removing a film in regions corresponding to streets, forming a modified layer inside a wafer by irradiating a laser beam from the back surface side of the wafer, and applying an external force to divide the wafer into individual device chips. The method ensures that the distance from the end part of the street in the width direction to the region from which the film is removed is set equal to or shorter than a predetermined upper limit value. This results in the formation of a step between the exposed substrate and the film-coated region at the outer edge of the device chip during the dividing step.
