Abstract: PURPOSE: A method for manufacturing a semiconductor device is provided to be capable of preventing over-etch and NP bias problem caused by gate patterning. CONSTITUTION: A plurality of gates are formed on a semiconductor substrate defined by an NMOS and PMOS region. An insulating layer is formed on the resultant structure, wherein the thickness of the insulating layer is thicker than that of the gates. The insulating layer is partially removed in order to leave the insulating layer on the gate. Then, the insulating layer is also removed so as to expose the upper portion of the gates. An NMOS gate(23a) and a PMOS gate(23b) are formed by selectively implanting gate ions into one region of the NMOS or PMOS region. The remaining insulating layer is then entirely removed.

Title: Optical-based sensing devices
IPC: G01N21/64
Filed: 1999-08-26
Abstract: An optical-based sensor (10) for detecting the presence or amount of an analyte using both indicator and reference channels. The sensor has a sensor body (12) with a source of radiation embedded therein (18). A matrix layer is disposed on the surface of the sensor body which layer is permeable to an analyte and comprises fluroescent indicator molecules responsive to the concentration of the analyte. Radiation emitted by the source interacts with indicator membrane (3) indicator molecules (16) proximate the surface of the body. At least one optical characteristic of these indicator molecules varies with analyte concentration. For example, the level of fluorescence of fluorescent indicator molecules or the amount of light absorbed by light-absorbing indicator molecules can vary as a function of analyte concentration. In addition, radiation emitted by the source also interacts with reference membrane indicator molecules proximate the surface of the body. Radiation (e,g., light) emitted or reflected by these indicator molecules enters and is internally reflected in the sensor body. Photosensitive elements within the sensor body generate both indicator channel and reference channel signals to provide an accurate indication of the concentration of the analyte.

Title: Use of zeta potential during chemical mechanical polishing for end point detection
IPC: H01L21/306
Filed: 1999-10-13
Abstract: A technique for utilizing a sensor to monitor fluid pressure from a fluid bearing located under a polishing pad to detect a polishing end point. A sensor is located at the leading edge of a fluid bearing of a linear polisher, which is utilized to perform chemical-mechanical polishing on a semiconductor wafer. The sensor monitors the fluid pressure to detect a change in the fluid pressure during polishing, which change corresponds to a change in the shear force when the polishing transitions from one material layer to the next. In order to ensure that there is a noticeable difference in the shear force variation at the polishing end point, a slurry having a particular pH level is selected. The pH level ensures that the zeta potential changes noticeably from one material to the next, so as to induce a change in the shear force, which is detected by a change in the fluid pressure.
