Recently filed patent applications of Disco Corporation in USPTO?

Publication number: US20220016731A1
Application number: 17/448,945

A laser processing method for processing a wafer using a laser processing apparatus, where the laser processing apparatus includes a holding unit, a laser oscillator for emitting a pulsed laser beam, a polygon mirror for dispersing the pulsed laser beam emitted from the laser oscillator, a condenser for condensing the pulsed laser beam dispersed by the polygon mirror and applying the condensed pulsed laser beam to the workpiece and dispersed region adjuster for controlling a dispersed region of the pulsed laser beam, where the laser processing method includes steps of holding the workpiece on the holding unit and processing the workpiece held by the holding unit by applying the pulsed laser beam, where during processing, the dispersed region adjuster controls the dispersed region of the pulsed laser beam by causing the pulsed laser beam to follow a direction in which the mirror facets of the polygon mirror are rotated.

Application number: 17/380,606

A method of processing a wafer includes a wafer preparing step of preparing a measurement wafer and a product wafer, a measurement etching step of supplying a gas in a plasma state to first areas of the measurement wafer that correspond to streets thereon to form grooves in the measurement wafer, a measuring step of demarcating a plurality of concentric areas in an array from a center to an outer circumference of the measurement wafer, and measuring depths of the grooves in the respective concentric areas, a thickness adjusting step of adjusting a thickness of the product wafer such that the product wafer is progressively thinner in areas thereof that correspond to the areas of the measurement wafer where the grooves are shallower, and an etching step of supplying a gas in a plasma state to second areas of the product wafer that correspond to streets thereon.
