RIT Engineering Laboratory receives high tech system from Heidelberg Instruments to improve lithographic process for semiconductor fabrication
Heidelberg, Germany, May 09, 2016: Rochester Institute of Technology recently installed a high tech laser lithography system in the university’s Semiconductor and Microsystems Fabrication Lab to advance semiconductor research and development. The system, a DWL66+ from Heidelberg Instruments, is capable of photo-mask fabrication and direct-write lithography applications—the complex process of imaging silicon wafers with microelectronic design patterns for integrated circuits.
Installed in RIT’s Semiconductor and Microsystems Fabrication Lab (SMFL), the new equipment will be used as part of several key research initiatives at the university in the areas of solar and fuel cell technology, nano-photonics and novel nanomaterials, as well support students in undergraduate and graduate programs in microelectronic engineering, and a doctoral program in microsystems engineering.
The new equipment was funded in part by the National Science Foundation through its Major Research Instrumentation program for: “Acquisition of a direct-write laser system for innovations in electronic and photonic device design.”
Lithography, also referred to as photolithography, is a multi-step, precision process to build, layer-upon-layer, the electronic circuitry on silicon wafers that is then used as the basis for electronic devices. The new system has several advantages over traditional proximity or projection optical lithography, said Karl Hirschman, SMFL director and professor of microelectronic engineering in RIT’s Kate Gleason College of Engineering.
“This system has the ability to handle a variety of substrate shapes and sizes, make on-demand pattern changes, and implement pattern variations within a sample. This research-scale system has wonderful flexibility and is a perfect fit for our facility,” said Hirschman. “DWL patterning can be intermixed with e-beam or optical exposure levels, providing design flexibility on pattern transfer processes. The DWL also offers new capabilities in lithography that are not possible with our other imaging systems.”
With more than 10,000 square feet of clean room space, the SMFL is equipped with micro-fabrication and metrology equipment to support research programs in semiconductor materials and devices, nano-electronics, MEMS devices and sensors, photonic devices and nanomaterials. All these systems will be utilized as part of RIT’s role in AIM Photonics, a New York-based consortium, led by SUNY Polytechnic, Rochester Institute of Technology and the University of Rochester, to focus on advancing integrated photonics, technology essential to the nation’s manufacturing capabilities in such areas as high-speed data and telecommunications.
