Abstract: A wafer including a substrate, a dielectric layer over the substrate, and a conductive layer over the dielectric layer is disclosed. The substrate has a main portion. A periphery of the dielectric layer and the periphery of the main portion of the substrate are separated by a first distance. A periphery of the conductive layer and the periphery of the main portion of the substrate are separated by a second distance. The second distance ranges from about a value that is 0.5% of a diameter of the substrate less than the first distance to about a value that is 0.5% of the diameter greater than the first distance.

Abstract: An improved structure of multi-functional hand tool, wherein, a pushing axle rod is screw connected with a chuck, a pushing axle rod is screw connected with a driving rod; bearings are slipped over a positioning sleeve, then the positioning sleeve, the pushing axle rod and the chuck are together placed in a pipe body with the bearings. The positioning sleeve can be rotated in the bearings. A front cover is locked in the front end of the pipe body; the chuck is extended out of the front cover. The pushing member is screwed in the pipe body to render a hole on a rear enlarged threaded portion of the pushing member to be exactly located at a position limiting slot of the pipe body. The external sleeve then is slipped over the pipe body, and an inner screw hole of the external sleeve is aligned with the position limiting slot of the pipe body. Then the positioning screw rod is screwed in the inner screw hole to extend through the position limiting slot and the hole of the pushing member. Thereby, the external sleeve pushes the pushing member when the external sleeve is rotated; the pushing member in turn moves the chuck into/out of the positioning sleeve to thereby insert/take a grinding member into/out of the chuck.
