    摘要: The present invention relates to systems and methods to regulate spacer deposition. The present invention employs a spacer deposition controller to control a spacer deposition component that deposits a spacer on a portion of a wafer. During and/or after spacer deposition, light can be directed at the spacer, wherein light reflected from the spacer is measured to determine parameters associated with the spacer deposition process. A processor operatively coupled to a measurement system and the spacer deposition controller utilizes the parameters to determine if the spacer process is proceeding in a suitable manner via comparing the measured parameters with stored acceptable parameters. If it is determined that the spacer deposition process is not proceeding as desired, then the measured parameters can be employed by the spacer deposition controller to adjust the spacer deposition process on the portion of the wafer and on subsequent portions of wafers.

    摘要: A method for forming a semiconductor device comprises forming a first layer over a semiconductor substrate. At least one hole is formed through the first layer. A bottom anti-reflective coating (BARC) layer is formed in the at least one hole. A first heating is performed to heat the BARC layer to a flow temperature. A second heating is performed to heat the BARC layer to a hardening temperature so that the BARC layer hardens, wherein the hardening temperature is greater than the flow temperature. An etch is performed to form a trench in the first layer and over the at least one hole, wherein the hardened BARC layer in the at least one hole acts as an etch resistant layer during the etch. As an alternative to the second heating step, the BARC may be simply hardened. The first and second heating may be performed within a heating chamber without removing the semiconductor substrate.

    摘要: A system for characterizing a chemical mechanical polishing process is provided. The system includes a wafer that has a metal, polysilicon, and/or dielectric layer and/or substrate and a temperature sensor located in and/or on the metal, polysilicon and/or dielectric layer and/or substrate. The system also includes a temperature monitoring system that can read the wafer temperature from the temperature sensors and that can analyze the wafer temperature to characterize the chemical mechanical polishing process. Such characterization includes producing information concerning relationships between wafer temperature and polishing rate, polishing uniformity and introduction of defects during polishing. Such relationships are correlated with wafer temperature as related to parameters like polishing time, pressure, speed, slurry properties and wafer/metal layer properties. Such characterization can be employed, for example, to better understand a CMP process, to facilitate initializing subsequent chemical mechanical polishing processes and/or apparatus and/or to control such chemical mechanical polishing processes and/or apparatus by monitoring and/or controlling wafer temperature.

    摘要: An exemplary method of using silicon containing imaging layers to define sub-resolution gate structures can include depositing an anti-reflective coating over a layer of polysilicon, depositing an imaging layer over the anti-reflective coating, selectively etching the anti-reflective coating to form a pattern, and removing portions of the polysilicon layer using the pattern formed from the removed portions of anti-reflective coating. Thus, the use of thin imaging layer, that has high etch selectivity to the organic underlayer, allows the use of trim etch techniques without a risk of resist erosion or aspect ratio pattern collapse. That, in turn, allows for the formation of the gate pattern with widths less than the widths of the pattern of the imaging layer.
