Bio

Lars P. Tatum is a PhD student in Electrical Engineering & Computer Sciences at UC Berkeley working under the supervision of Prof. Tsu-Jae King Liu. He began his graduate studies in 2019 after graduating with a B.S. in Electrical Engineering from the University of Florida. His research investigates novel semiconductor devices and process technology to extend Moore’s Law. Lars is trained in finite-element-method device simulation, fabrication/characterization of semiconductor device structures, and digital IC design.

Research

Micro/nanoelectromechanical (M/NEM) switches can achieve zero leakage current and have abrupt switching characteristics; therefore, they are attractive for ultra-low-power computing applications. Additionally, the back-end-of-line metallic interconnects of ICs can be used to implement non-volatile NEM switches, enabling enhanced functionality with low incremental manufacturing cost. Lars is designing M/NEM devices and circuits for energy-efficient computation and memory. Furthermore, as transistor scaling has slowed, it is imperative we find new methods to boost the performance and functionality of CMOS technologies. To this end, Lars is researching novel substrates and gate stacks to enable low-cost manufacturing and increased functionality of state-of-the-art transistor devices.
