ABOUT
Semiconductor Materials & Devices Laboratory (SMDL)
Our laboratory is a group of Semiconductor Materials and Devices Laboratory (SMDL) at the department of Electrical and Computer Engineering in Seoul National University. A field of research covers nonvolatile memory, flexible electronics, gas sensors & bio sensors, thin film transistors (TFTs), reconfigurable devices & circuits, and neuromorphic devices & circuits.
The devices and circuits are fabricated mainly at ISRC (Inter-University Semiconductor Research Center) located inside the campus of Seoul National University. Most of students in our laboratory have an experience to fabricate semiconductor devices and circuits by themselves. Some of devices and circuits are provided from semiconductor companies through collaboration projects. The scope of research in our laboratory includes device fabrication, measurement, characterization, and modeling.
We have five probe stations (probe card, temperature, gas, moisture, laser light), four semiconductor parameter analyzers, oscilloscope, spectrum analyzer, low noise current/voltage amplifier, lock-in amplifier, laser light sources (650 nm, 550 nm, 405 nm in wavelength), continuous spectrum light source, inkjet printer, and transfer printer.
