Publication number: 20080128708Abstract: The surface of a gallium nitride single crystal substrate is processed, e.g., comprising steps by planarizing the top side and the bottom side of a gallium nitride original substrate positioned on a support bed; radiating light having wavelengths ranging from 370 to 800 nanometers (nm) onto the planarized gallium nitride original substrate; measuring transmittance of the gallium nitride original substrate; and confirming whether the transmittance is within the range of 65 to 90%. A gallium nitride single crystal substrate obtained through the method of processing the surface has high transmittance ranging from 65 to 90% measured using light having wavelengths of 370 to 800 nm. The thickness ratio (DLa/DLb) of the damage layers on the both sides of the gallium nitride single crystal substrate can be obtained within the range of 0.99 to 1.01.Type: ApplicationFiled: October 29, 2007Publication date: June 5, 2008Applicant: Samsung Corning Co., Ltd.Inventors: Jin Suk Jeong, Ki Soo Lee, Kyoung Jun Kim, Ju Heon Lee, Chang Uk Jin

Patent number: 7381576Abstract: A method for monitoring precision of placement of semiconductor wafers in a semiconductor processing apparatus includes measuring thickness of an insulating film on a surface of a semiconductor substrate before etching a portion of the insulating film from the surface of the semiconductor substrate. The method further includes re-measuring the thickness of the insulating film to determine etch rates for the film at selected locations on the surface of the semiconductor wafer, and based on the determined etch rates, determining misalignment of the semiconductor wafer.Type: GrantFiled: August 15, 2005Date of Patent: June 3, 2008Assignee: Infineon Technologies Richmond, LP.Inventor: Igor Jekauc

Publication number: 20080122037Abstract: A method of preventing the formation of cracks on the backside of a silicon (Si) semiconductor chip or wafer during the processing thereof. Also provided is a method for inhibiting the propagation of cracks, which have already formed in the backside of a silicon chip during the processing thereof and prior to the joining thereto of a substrate during the fabrication of an electronic package. The methods entail either treating the backside with a wet etch, or alternatively, applying a protective film layer thereon prior to forming an electronic package incorporating the chip or wafer.Type: ApplicationFiled: August 3, 2006Publication date: May 29, 2008Inventors: Timothy H. Daubenspeck, Jeffrey P. Gambino, Jerome B. Lasky, Christopher D. Muzzy, Wolfgang Sauter

Publication number: 20080121880Abstract: A method of measuring thickness of a layer in an image sensor and pattern for the same are disclosed, by which layer thickness measurement of an image sensor is enabled in the course of fabrication. Embodiments relate to a method of measuring thickness of a layer in an image sensor in which a first epitaxial layer may be formed over a semiconductor substrate. A photoresist pattern may be formed by coating and patterning photoresist over the first epitaxial layer. A plurality of trenches in the first epitaxial layer may be formed by performing a dry etch on the photoresist pattern. A doped layer may be formed at a bottom of each of the trenches by implanting antimony (Sb) using the photoresist pattern as a mask. After removing the photoresist pattern, a second epitaxial layer may be formed over the first epitaxial layer including a plurality of the trenches. The thickness of the second epitaxial layer may be measured to determine the thickness of one of the doped layers.Type: ApplicationFiled: November 5, 2007Publication date: May 29, 2008Inventor: Jeong-Su Park

Publication number: 20080124817Abstract: Methods and systems are provided of fabricating a compound nitride semiconductor structure. A substrate is disposed within a processing chamber into which a group-III precursor and a nitrogen precursor are flowed. A layer is deposited over the substrate with a thermal chemical-vapor-deposition process using the precursors. The substrate is transferred to a transfer chamber where a temperature and a curvature of the layer are measured. The substrate is then transferred to a second processing chamber where a second layer is deposited.Type: ApplicationFiled: August 23, 2006Publication date: May 29, 2008Applicant: Applied Materials, Inc.Inventors: David Bour, Sandeep Nijhawan, Lori D.
