    摘要: An apparatus for aligning a mask having an image and at least one complimentary alignment mark to a substrate having a first surface and a substantially opposing second surface. The substrate further has at least one alignment mark on the second surface. A mask support supports the mask in proximity to the first surface of the substrate. A substrate support supports the substrate with the first surface in proximity to the mask. An alignment means aligns the at least one alignment mark on the second surface of the substrate to the at least one complimentary alignment mark on the mask. An exposure source projects the image of the mask onto the first surface of the substrate, and a controller controls the mask support, substrate support, alignment means, and exposure source.

    摘要: A technique for reducing silicon defect induced transistor failures, such as latch-up, in a CMOS or other integrated circuit structure includes fabricating the integrated circuit structure on a substrate and implanting a buried layer beneath a surface of the integrated circuit. The buried layer implant is the final implanting step during fabrication of the integrated circuit structure. In another technique, fabricating the integrated circuit structure includes performing multiple sequential processes some of which are performed at elevated temperatures above about 500.degree. C. A buried layer is implanted beneath a surface of the integrated circuit. After implanting the buried layer, the substrate is subjected to a fabrication process at an elevated temperature above about 800.degree. C. only once. Propagation of defects, such as in-the-range defects or ion enhanced stacking faults, from the buried layer to other device layers during the fabrication process is reduced.

    摘要: A method of planarizing a first side of a semiconductor wafer with a polishing system includes the step of polishing the first side of the wafer in order to remove material from the wafer. The method also includes the step of moving a lens of a confocal optical system between a number of lens positions so as to maintain focus on the first side of the wafer during the polishing step. The method further includes the step of determining a rate-of-movement value based on movement of the lens during the moving step. Moreover, the method includes the step of stopping the polishing step if the rate-of-movement value has a predetermined relationship with a movement threshold value. An apparatus for polishing a first side of a semiconductor wafer is also disclosed.

    摘要: The present invention provides a method for manufacturing a semiconductor device on a substrate. The process involves denuding the substrate by heating to create a denuded zone within the substrate. A screen oxide layer is formed prior to implanting ions into the substrate. This oxide layer remains during the implantation step. The screen oxide layer is removed when forming gates for the semiconductor device.

    摘要: A method of polishing a first layer of a semiconductor wafer down to a second layer of the semiconductor wafer is disclosed. One step of the method includes heating a back surface of the semiconductor wafer to a first temperature level so as to cause a front surface of the semiconductor wafer to have a second temperature level. Another step of the method includes polishing the semiconductor wafer whereby material of the first layer is removed from the semiconductor wafer. The polishing step causes the second temperature level of the front surface to change at a first rate as the material of the first layer is being removed. The method also includes the step of halting the polishing step in response to the second temperature level of the front surface changing at a second rate that is indicative of the second layer being polished during the polishing step. Polishing systems are also disclosed which detect a polishing endpoint for a semiconductor wafer based upon heat conducted through the semiconductor wafer.
