Publication number: 20100151688Abstract: Embodiments disclosed herein generally include methods of ensuring uniform deposition on a substrate. The smallest gap between a portion of the substrate and the substrate support upon which the substrate rests may lead to uneven deposition of material or ‘thin spots’ on the substrate. Large area substrates, due to their size, are susceptible to numerous gaps at random locations. By inducing an electrostatic charge on the substrate prior to placing the substrate onto the substrate support, the substrate may be placed generally flush against the substrate support. The electrostatic charge on the substrate creates an attraction between the substrate and substrate support to pull substantially the entire surface of the substrate into contact with the substrate support. Material may then be substantially uniformly deposited on the substrate while reducing ‘thin spots’.Type: ApplicationFiled: December 10, 2009Publication date: June 17, 2010Applicant: Applied Materials, INC.Inventors: Young Jin Choi, Gaku Furuta, Soo Young Choi, Beom Soo Park
