Latest Patents
Chaos Tsai holds a patent titled "Assistant pattern for measuring critical dimension of main pattern in semiconductor manufacturing." This patent describes a method that involves receiving an integrated circuit (IC) layout with a pattern layer. The pattern layer contains a main layout pattern, where the dimension W of the main layout pattern along a first direction exceeds the critical dimension (CD) measurement upper limit of a wafer metrology tool. The method further includes the addition of multiple assistant layout patterns into the pattern layer. These assistant patterns consist of a pair of CD assistant layout patterns positioned on both sides of the main layout pattern along the first direction. The dimensions W and D of these patterns are greater than the printing resolution in a photolithography process and are equal to or less than the wafer metrology tool's CD measurement upper limit. This innovative approach enhances the accuracy of measurements in semiconductor manufacturing.
