    摘要: Laser machining fired ceramic and other hard and/or thick materials includes scribing a workpiece with a laser beam along a sequence of parallel laser paths within a cutout region of the workpiece. The scribing creates a kerf in the cutout region that widens as the laser beam advances along the sequence. The sequence may begin with an inner portion of the cutout region and end with an outer edge thereof such that debris is directed away from the laser paths to increase throughput and create a high quality opening in the workpiece. High quality structures may also be cut out from the workpiece. The method includes directing a high velocity stream of gas to an interface of the laser beam and the workpiece to redirect the flow of debris and cool the interface. The method may also adjust a focus depth of the laser beam as it deepens the kerf.

    摘要: A method of forming a filled via with an optically transmissive material and a resulting product. The method comprises drilling a via in a panel and filling the via with an optically transmissive material. The method can also be used to create a light transmissive section of a housing. A light source directed to one side of the via is seen through the optically transmissive material so as to be visible to a viewer viewing a surface at the second side of the via.

    摘要: An improved method of forming a semiconductor device is described. The method comprises forming a dielectric layer on a substrate, forming a photoresist layer on the dielectric layer, then patterning the photoresist layer to define a region to be etched. After forming an etched region within the dielectric layer, the photoresist layer is removed and the etched region is cleaned. The etched region is cleaned by applying a buffered oxide etch dip, followed by an amine based dip.
