Title: Method of slicing a workpiece through use of a saw, and a wire saw
Inventor: OISHI HIROSHI
IPC: B28D5/04
Filed: 1998-01-20
Granted: 2001-01-01
Abstract: There is disclosed a method of slicing a workpiece through use of a wire saw. The workpiece is pressed at a predetermined feed rate against a wire which moves from a wire feed side to a wire take-up side and slices the workpiece into wafers while abrasive grain slurry is fed to the press contact portion between the wire and the workpiece. The feed rate of the workpiece is controlled according to the size of abrasive grains in the abrasive grain slurry, such that a decrease in the slicing stock removal stemming from a decrease in the size of abrasive grains during slicing is compensated with an increase in the slicing stock removal effected by decreasing the feed rate of the workpiece. The method can make the thicknesses of sliced wafers uniform to the extent possible.

Title: Implanted structures and methods of formation
Inventor: WU ZHIQIANG
IPC: B81C1/00
Filed: 1998-03-23
Granted: 2001-01-21
Abstract: Methods are disclosed for forming shaped structures of silicon-containing matcrial with ion implantation and an etching process which is selective to silicon-containing matcrial implanted to a certain concentration of ions or with an etching process which is selective to relatively unimplanted silicon-containing material. In general, the methods initially involve providing a layer of silicon-containing material such as polysilicon or epitaxial silicon on a semiconductor substratc. The layer of silicon-containing material is then masked, and ions are implanted into exposed portions of the layer of silicon-containing material. The mask is removed, and the aforementioned selective ctching process is conducted to result in one of an implanted and a relatively unimplanted portion of the layer of silicon-containing material being etched away and the other left standing to form a shaped structure of silicon-containing material. One preferred selective etching process uses an etchant solution comprising a selected weight percentage of tetramethyl ammonium hydroxide in deionized water. The etchant solution etches relatively unimplanted silicon-containing material implanted up to 60 times faster than it etches silicon-containing material implanted to beyond a threshold concentration of ions. The various methods are used to form raised shaped structures, shaped openings, polysilicon plugs, capacitor storage nodes, surround-gate transistors, free-standing walls, interconnect lines, trench capacitors, and trench isolation regions.

Inventor: MORIWAKI HISAYOSHI
IPC: H04N19/60
Filed: 1998-09-04
Granted: 2000-07-11
Abstract: When a spectrally spread additional information signal, obtained by spectrum spreading addition information such as an anti-duplication control signal or copyright information, is superimposed on a video signal, the level of the spectrally spread additional information signal is controlled according to the scatter of pixel values in each block comprising plural pixels. The sensitivity of detecting additional information from the spectrally spread addition information signal is therefore improved, and the visual effect of the spectrally spread additional information signal on a reproduced image is suppressed.

Title: Process for applying a metal structure to a workpiece, the treated workpiece and a solution for electroplating copper
Inventor: CHEN LIN-LIN
IPC: H01L21/445
Filed: 1999-03-20
Granted: 2004-11-11
Abstract: This invention employs a novel approach to the copper metallization of a workpiece, such as a semiconductor workpiece. In accordance with the invention, an alkaline electrolytic copper bath is used to electroplate copper onto a seed layer, electroplate copper directly onto a barrier layer material, or enhance an ultra-thin copper seed layer which has been deposited on the barrier layer using a deposition process such as PVD. The resulting copper layer provides an excellent conformal copper coating that fills trenches, vias, and other microstructures in the workpiece. When used for seed layer enhancement, the resulting copper seed layer provides an excellent conformal copper coating that allows the microstructures to be filled with a copper layer having good uniformity using electrochemical deposition techniques. Further, copper layers that are electroplated in the disclosed manner exhibit low sheet resistance and are readily annealed at low temperatures.
