Patent number: 9330917Abstract: Methods of forming a passivation layer on a workpiece are disclosed. These methods utilize a SiC forming polymer to form the passivation layer. In addition, while the polymer is being heated to form SiC, a second result, such as annealing of the underlying workpiece, or firing of the metal contacts is achieved. For example, the workpiece may be implanted prior to coating it with the polymer. When the workpiece is heated, SiC is formed and the workpiece is annealed. In another embodiment, a workpiece is coating with the SiC forming polymer and metal pattern is applied to the polymer. The firing of workpiece causes the metal contacts to form and also forms SiC on the workpiece.Type: GrantFiled: February 20, 2013Date of Patent: May 3, 2016Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: Nicholas Bateman, Deepak Ramappa
