Abstract:
1. A method for manufacturing semiconductor devices, the method comprising: providing a semiconductor wafer; separating the semiconductor wafer into at least a first cell and a second cell; assigning the first cell a first dosage and assigning the second cell a second dosage; decomposing the first dosage into a first dimension component and a second dimension component; decomposing the second dosage into a third dimension component and a fourth dimension component; converting the first dimension component into a first velocity, converting the second dimension component into a second velocity, converting the third dimension component into a third velocity, and converting the fourth dimension component into a fourth velocity; implanting dopants into the first cell using the first velocity and the second velocity, the implanting dopants being performed with an ion implanter; and implanting dopants into the second cell using the third velocity and the fourth velocity, the implanting dopants being performed with the ion implanter.
