Patent number: 9824894Abstract: Described herein are methods for flattening a substrate, such as a semiconductor wafer, to reduce bowing in such substrates. Methods include treating or bombarding a backside surface of a substrate with particles of varying doses, densities, and spatial locations. Particle bombardment and selection is such that the substrate becomes more planar by selectively increasing or decreasing z-height points to reduce overall deflection. One or more tensile or compressive films can be added to the backside surface to be selectively relaxed at specific point locations. Such methods can correct bowing in substrates resulting from various fabrication processes such as thermal annealing.Type: GrantFiled: April 9, 2015Date of Patent: November 21, 2017Assignee: TOKYO ELECTRON LIMITEDInventor: Anton J. deVilliers
