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 and Devices group’s clean room. The clean room staff have extensive expertise in the synthesis, fabrication, and processing of nanomaterials and the design and development of nanodevices, including manufacturing of micro/nano-electro-mechanical systems. They provide not only technical expertise and training but also user support. The clean room spans over 18,000 square feet and contains a remarkable depth and breadth of nanofabrication equipment. See below for the major equipment list.

Virtual 360° tour of the CNM cleanroom

The CNM cleanroom features unique, state-of-the-art toolsets for the creation of devices at the nanoscale. Scientists from around the world use fabrication tools and other capabilities in the cleanroom to invent new technologies and explore the evolution of the universe.

CNM Cleanroom 360 Tour

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, allows synthesis of a variety of materials, including metal, dielectric, and complex oxides using multi-chamber sputtering tools, electron beam evaporation, and plasma-enhanced chemical vapor deposition (PECVD). A unique synthesis tool includes microwave plasma CVD for the synthesis of diamond films

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 atomic force microscope, as well as sample/wafer processing tools, including a critical point dryer and a cleaving machine.
