  • Selectable device options for characterizing semiconductor devices
    Patent number: 7814454
    Abstract: A system, method and program product that allows multiple devices to be placed between pads such that a Back End Of Line (BEOL) mask change can be used to select different device options. A system is disclosed for implementing a testsite for characterizing devices in an integrated circuit technology, and includes: a system for designing a plurality of device options for a set of chip pads; a system for designing a pseudo wiring layout for each of the plurality of device options; a system for selecting one of the device options; a system for mapping the pseudo wiring layout for a selected device option to a predetermined design level; and a system for outputting a configured mask design at the predetermined design level having a wiring layout mapped for the selected device option.
