Abstract:
1. A method of fabricating a semiconductor chip, the method comprising: providing a workpiece having a first semiconductor device and a second semiconductor device arranged thereon; implanting the semiconductor chip with a dopant species using a first implantation process in a first orientation of the workpiece, wherein the first implantation process comprises implanting the dopant species at a first angle with respect to a top surface of the workpiece; and implanting the semiconductor chip with the dopant species using a second implantation process in at least one second orientation of the workpiece, wherein the second implantation process comprises implanting the dopant species at a second angle with respect to the top surface of the workpiece, wherein the second angle is different than the first angle, and wherein the first semiconductor device comprises different operating parameters than the second semiconductor device.
