摘要： A machining tool (1) includes a tooth (3) having a tooth tip (4) being covered with cutting particles (5) to form a plurality of geometrically undefined cutting portions. The tooth tip (4) is designed to be asymmetrical. The machining tool (1) thus is a 2-in-1 machining tool including differently designed sides of the tooth tips (4) which are suitable for efficiently machining different materials.

摘要： A circular saw blade includes a body defined by a planar metallic plate, an arbor disposed at a center of the body defining an axis of rotation for the blade, a plurality of projections extending away from a perimeter of the body, the projections each having a leading edge and a trailing edge, and a plurality of teeth disposed at the projections such that one tooth is located at the leading edge of each of the projections. A diameter of the blade is 7¼ inches, and a total of twenty-seven projections and twenty-seven teeth are disposed at the perimeter of the body.

摘要： Methods and apparatus for pre-treating semiconductor wafers before edge trimming to enhance wafer edge quality prior to thinning the semiconductor wafers from an initial thickness, and increasing yield post-thinning of the pre-treated, edge trimmed semiconductor wafers. An apparatus includes a stage configured to receive one of a device wafer or a carrier wafer having a device wafer mounted thereto thereon, a laser tool located above the stage and oriented to direct a laser beam downwardly toward the stage, and a vertically movable blade rotatable about a horizontal axis along a radius from a vertical axis at a center of the device wafer and positionable proximate to and radially inward of an outer periphery of the device wafer.

摘要： A tip saw has disk-shaped and comprises cutting blade pieces, support pieces, and a base metal. The cutting blade pieces are disposed at blade edges of the tip saw. The support pieces are disposed between adjoining two of the cutting blade pieces. The cutting blade pieces and the support pieces are configured to be thicker than a thickness D1 of the base metal of the tip saw (D2>D1). The support pieces have a thickness equal to or nearly equal to the thickness D2 of the cutting blade pieces (D3=D2 or D3≈D2). Consequently, the width of a cut groove Pc formed on a work material by the cutting blade pieces can be maintained wider than the thickness D1 of the base metal of the tip saw by the support pieces without increasing the number of the cutting blade pieces of the tip saw.
