Abstract
The invention is a method for displaying wafer test results from an integrated circuit tester in real time. The method comprising the steps of: (a) receiving wafer dimensions and die dimensions from a wafer handler; (b) creating a template representative of a wafer having cells representative of a die from the wafer dimensions and the die dimensions; (c) displaying the template; (d) invoking a tester to test a selected die of a selected wafer; (e) receiving test results from the tester; (f) displaying the test results on a selected cell which corresponds to the selected die; and (g) repeating steps (d)-(f) as required.
