The CNI Clean Room in the Morris A. Schapiro Center for Engineering and Physical Science Research (CEPSR) is dedicated to providing the instrumentation, technical expertise, and team-teaching environment to stimulate collaborative research in nanoscale technology. The facility supports the creation and evaluation of devices and materials with state of the art fabrication equipment.
The Clean Room is a multidisciplinary laboratory that supports research across many different departments within Columbia University as well as researchers from other academic institutes and industrial users. The laboratory supports not only materials and device research in physics, electrical engineering, applied physics, mechanical engineering and chemistry, but it also facilitates research interaction and collaboration between the physical, chemical, biological and medical disciplines and is open to all. The facility represents a strategic capability for the Nanoscale Science and Technology research on the Columbia Campus.
The new CNI Clean Room (target opening date: March 2017) will occupy approximately 5,000 square feet of space. It is divided into 7 separate bays, each dedicated to a set of related fabrication processes:
- Optical lithography bay consisting of dedicated fume hoods and spinners, two mask aligners (one for DUV applications), two mask fabrication systems: a manual Laser Writing and Mask Fabrication system (3µm resolution) and an automatic Laser Writer system with submicron resolution.
- Wet chemical room with an automatic RCA bench
- Plasma bay with Reactive Ion Etching (RIE) plasma processing based on chlorine and fluorine chemistries, as well as Deep RIE for silicon etching, and PECVD for Oxide and Nitride deposition.
- Deposition bay including two sputtering systems (dedicated to metals and dielectrics respectively), an e-beam evaporator, Atomic Layer Deposition, and a thermal evaporator (the two latter are located in the Plasma bay due to space considerations).
- SEM bay (with e-beam writing capabilities)
- Furnace bay with Oxide, Nitride, Carbide, and anneal capabilities.
- Backend room consisting of a Dicing saw, Chemical Mechanical Polishing system, Wire bonders (Al and Au), and a Critical Point Dryer.
Lithographic capabilities include nano-scale features down to less than 50 nanometers using a Nanobeam nB4 E-beam Writing system which is located in the North West Corner building.
