Abstract:
Modular dies and modular masks that can be used during the manufacture of semiconductor devices are described. The modular mask can be used repeatedly to make multiple, substantially-similar modular dies. The modular die contains a substrate with an integrated circuit as well as a conductive layer containing a source metal and a gate metal connected respectively to the source and gate of the integrated circuit. The gate metal of the conductive layer is located only in an outer portion of the modular die. The modular die can be made by providing the integrated circuit in a first and second portion of the substrate, providing the conductive layer on both the first and second portions, making a first modular die by patterning the conductive layer on the first portion using the modular mask; moving the modular mask to the second portion and using it to make a second modular die by patterning the conductive layer on the second portion. Thus, fewer mask sets need to be made, improving efficiency and reducing costs. Other embodiments are described.
