Using Hybrid AFM / STM Lithography of Resist for Gate Patterning
We fabricated p-channel metal oxide semiconductor field effect transistors (pMOSFETs) using the method of hybrid AFM / STM lithography for gate level patterning. The gate level lithography required precise alignment capabilities, 100-nm resolution, and uniform patterning over transistor topography. Devices with 130-nm physical gate lengths and 100-nm effective channel lengths exhibited reasonable electrical characteristics. This pMOSFET fabrication demonstrates the capabilities of hybrid AFM / STM lithography and shows the system’s compatibility with semiconductor processing.
