Abstract
Abstract A production operator interface is created using self-contained ActiveX controls each of which provide an interface to a specific part of the overall test system. These controls all communicate among themselves automatically. The production interface uses an ActiveX "tester control" which provides an application programming interface to the rest of the software control system. A library of self-contained ActiveX controls is provided which contains "operator controls" which may be "dragged and dropped" into an operator window to provide the operator with information and the ability to control the test system. In addition a semiconductor test system needs to be adapted to work with one or more different packaged device handlers or wafer probers which position a semiconductor device for testing by the tester. An ActiveX operator control allows an operator to select a handler driver from a library of handler drivers.
