Abstract:
A system, comprising:an input/output device of a computer system, the input/output device providing a graphical user interface (GUI); one or more test instruments for producing electrical signals; a probe card having probe needles used for measuring electronic characteristics of devices on a semiconductor wafer, each device having cells, each cell having bond pads, the bond pads being spaced apart by a multiple of a first distance and a multiple of a second distance; a memory to store a predefined set of value corresponding to a temperature; a matrix switch; and an interface conduit electrically connecting the one or more test instruments, the computer system, the probe card, and the matrix switch, the semiconductor wafer being configured to move so that the probe needles measure the electrical characteristics of each cell for each device selected for testing based on a predefined value for the first distance and a predefined value for the second distance, each predefined value corresponding to a testing temperature.
