Vertical InAs/InGaAs nanowire MOSFETs are fabricated in a gate-last fabrication process, which allows gate-lengths down to 25 nm and accurate gate-alignment. These devices demonstrate high performance with transconductance of 2.4 mS/μm, high on-current, and off-current below 1 nA/μm. An in-depth analysis of the heterostructure MOSFETs are obtained by systematically varying the gate-length and gate location. Further analysis is done by using virtual source modeling. The injection velocities and transistor metrics are correlated with a quasi-ballistic 1-D MOSFET model. Based on our analysis, the observed performance improvements are related to the optimized gate-length, high injection velocity due to asymmetric scattering, and low access resistance.

The Washington Nanofabrication Facility is excited to offer users access to the Nanoscribe 3D Printer, a cutting-edge lithography system that produces unique 3D structures with 500nm resolution. This two-photon laser writer allows for additive manufacturing and maskless lithography within the same device. Its high printing resolution gives users greater design freedom when creating very small, complex parts with intricate features. Moreover, the Nanoscribe uses a simple workflow to rapidly fabricate micro-sized parts from virtual 3D models.
