Nanofabrication and Devices Capabilities

The CNM’s ability to fabricate complex nanostructures and devices is based on the advanced tool set housed within the Nanofabrication & Devices group’s clean room.

The CNM’s ability to fabricate complex nanostructures and devices is based on the advanced tool set housed within the Nanofabrication & Devices group​’s clean room. The bay-and-chase configured cleanroom spans over 11,500 square feet and contains a remarkable depth and breadth of nanofabrication equipment. The clean room staff have over 100 combined years of experience in fabrication, processing and MEMS design, development and manufacturing. See below for the full equipment list.

The CNM lithography suite is housed in three bays and includes several advanced lithography tools covering electron beam lithography, ion beam lithography, direct write optical lithography, contact printing with back-side alignment, nanoimprint lithography and holographic lithography. A deposition suite, also housed in three bays, can produce a variety of dielectric and metal films using multi-chamber sputtering tools, electron beam evaporation, and plasma enhanced chemical vapor deposition (PECVD). A unique set of carbon-based materials synthesis tools includes microwave plasma CVD for diamond films and an Atomate CNT-CVD System for producing CNT and graphene materials.

A wet etch bay includes electroplating, an electrochemical workstation and supercritical drying capability for post processing. The main tools in the dry etch bay are a dual chamber Oxford Instruments Plasmalab 100 and two tabletop March Plasma RIE tools. There are additional metrology tools for measurements of film thickness, critical dimensions, and stress including profilometers, a spectroscopic ellipsometer, and AFM. Finally, a biohazard level 2 biobay enables the functionalization of surfaces with biomolecules without breaking device cleanliness protocol.
