Patent number: 8993218Abstract: One or more techniques or systems for controlling a profile for photo resist (PR) are provided herein. In some embodiments, a first shield layer is formed on a first PR layer and a second PR layer is formed on the first shield layer. A first window is formed within the second PR layer during a first exposure with a mask. A second window is formed within the first shield layer based on the first window. A third window is formed within the first PR layer during a second exposure without a mask. Because, the third window is formed while the first shield layer and the second PR layer are on the first PR layer, a profile associated with the first PR layer is controlled. Contamination during ion bombardment is mitigated due to the controlled profile.Type: GrantFiled: February 20, 2013Date of Patent: March 31, 2015Assignee: Taiwan Semiconductor Manufacturing Company LimitedInventors: Li Huai Yang, Chien-Mao Chen
