Paresa Modarres won a Best in Session Paper Award at Techcon, held September 11-13 in Austin, Tex. A Ph.D. student in the School of Electrical and Computer Engineering (ECE) at Georgia Tech, she is advised by ECE Associate Professor Muhannad Bakir.
Ms. Modarres co-wrote the award-winning paper, "Three-Dimensional Integrated CMOS and High Density Biosensor Array Using Through-Silicon Vias," with Dr. Bakir and fellow Ph.D. student Ramasamy Ravindran.
Some of the current challenges with label-free biosensors include developing robust interconnection solutions and protecting underlying CMOS circuitry in the presence of biological samples. This group's paper describes a novel biosensing platform based on silicon nanowire (SiNW) field effect transistors (FETs) vertically stacked on a CMOS chip with the aid of through-silicon-vias (TSVs). This proposed sensing platform consists of a high density sensor chip (10,000 sensors/cm2) using SiNW FETs where the source and drain of each FET sensor are accessed using TSVs from the back side of the chip.
