Wilkes University

Micro/Nano-Fabrication Lab (SLC 17, 22, 13)

Primarily dedicated to microfabrication processing and device characterization, our Micro/Nano-Fabrication Lab teaches students how to fabricate devices in silicon. Instrumentation includes a Unitron Mask Alignment Microscope (MAM).

Lab experience offers a series of experiments which examine various unit fabrication processes. Additionally, students learn to integrate our current semiconductor processing capabilities to obtain and characterize operational bipolar junction transistors. Hands-on instruction focuses on teaching scientific principles dictating which process operations are required and what these operations accomplish. Capabilities include wafer characterization and inspection, cleaning, oxidation, photolithography, wet and dry etching, pattern transfer inspection, dopant deposition and diffusion, and electrical testing and process simulation.
