Patent number: 8975162Abstract: Methods of dicing semiconductor wafers, each wafer having a plurality of integrated circuits, are described. For example, a method includes applying a protection tape to a wafer front side, the wafer having a dicing tape attached to the wafer backside. The dicing tape is removed from the wafer backside to expose a die attach film disposed between the wafer backside and the dicing tape. Alternatively, if no die attach film is initially disposed between the wafer backside and the dicing tape, a die attach film is applied to the wafer backside at this operation. A water soluble mask is applied to the wafer backside. Laser scribing is performed on the wafer backside to cut through the mask, the die attach film and the wafer, including all layers included within the front side and backside of the wafer. A plasma etch is performed to treat or clean surfaces of the wafer exposed by the laser scribing. A wafer backside cleaning is performed and a second dicing tape is applied to the wafer backside.Type: GrantFiled: December 3, 2013Date of Patent: March 10, 2015Assignee: Applied Materials, Inc.Inventors: Wei-Sheng Lei, Brad Eaton, Aparna Iyer, Saravjeet Singh, Madhava Rao Yalamanchili, Ajay Kumar
