Patent TW-380080-B (TW)
Title: Wafer carrier head with inflatable bladder and attack angle control for polishing
Inventor: APPEL GREGORY A
IPC: B24B49/00
Filed: 1998-12-15
Granted: 2000-01-21
Abstract: A carrier head that holds an object such as a wafer for a polishing system can be rotated during polishing. One such carrier head includes a sensor that determines the relative orientation of (or the angle between) a movable chuck and a fixed drive structure. A control system uses these measurements to select the edge pressure applied to the wafer or the chuck to control the attack angle of the wafer against polishing pads. By actively adjusting the attack angle, a carrier head can accommodate torques about an axis not in the plane of contact between the wafer and the polishing pad even when the wafer is otherwise free to rotate about the axis. One carrier head includes a drive plate with projections ending with balls that are disposed in matching openings in a carrier plate. Radial elongation of openings and curvature of the balls permit rotation of the carrier plate about an axis in plane passing between the carrier and drive plates. Another aspect of the invention provides a flexible bladder connected to a conduit formed in a drive shaft of the carrier head. A wafer is mounted adjacent the bladder so that pressure from the conduit causes the bladder to expand and apply a uniform pressure to the wafer for polishing.

Title: Method for forming resistors in semiconductor circuit by using the chemical clean
Inventor: LIN YE-SEN
IPC: H01L23/522
Filed: 1998-12-11
Granted: 2000-07-01
Abstract: The present invention discloses a method for forming resistors, particularly in the semiconductor circuit, by using the chemical clean. In the processing steps, the chemical clean is used to produce the resistors. First, ion-implantation is applied to the surface of the semiconductor substrate to form a N+ well region. The isolation layer is then deposited and vias are defined in the isolation layer. The chemical clean is applied to the boundary between the N+ well region and the via to form a resistor under a condition that the protection layer is not removed. Next, the chemical vapor deposition method is used to deposit poly-silicon on the via and the isolation layer. Finally, the poly-silicon plug in the metal interconnect is defined by lithography and etching.

Title: Method and pressure jetting machine for processing a semiconductor wafer
Inventor: XIN YUN-BIAO
IPC: B24C3/32
Filed: 2000-03-24
Granted: 2001-07-11
Abstract: A method for processing a semiconductor wafer sliced from a single-crystal ingot comprises subjecting the front and back surfaces of the wafer to a lapping operation to reduce the thickness of the wafer and to remove damage caused during slicing of the wafer. The wafer is then subjected to an etching operation to further reduce the thickness of the wafer and to further remove damage remaining after the lapping operation. The wafer is subsequently subjected to a double-side polishing operation to uniformly remove damage from the front and back surfaces caused by the lapping and etching operations, thereby improving the flatness of the wafer and leaving polished front and back surfaces. Finally, the back surface of the wafer is subjected to a back surface damaging operation in which damage is induced in the back surface of the wafer while the front surface is substantially protected against being damaged or roughened. A pressure jetting machine of the present invention includes a wafer holder that supports the wafer in the pressure jetting machine such that the back surface of the wafer is exposed to the jetted abrasive slurry while the front surface is supported by the holder in spaced relationship above a support surface of the machine to inhibit damaging engagement between the support surface and the front surface of the wafer.

Title: Prefix search method and data structure using compressed search tables
Inventor: VAN LUNTEREN JAN
IPC: G06F17/30
Filed: 2000-11-14
Granted: 2002-07-11
Abstract: The invention relates to a system in which given search keys are evaluated, segment by segment, to search through tree-structured tables for finding an output information corresponding to the longest matching prefix. For at least one of the segments, only selected bits of the search key segment are used as index for accessing an associated table where test values are stored which are to be compared to the respective search key segment. The bits to be selected are determined by an index mask, reflecting the distribution of the valid test values in the table entries (and valid search key segment values). This allows table compression for minimizing storage requirements and search time. A procedure is disclosed for generating an optimum index mask in response to the set of valid test values.
