Research Summary:

Dr. Tsai's main research theme is the design and application of advanced control, simulation, signal processingoptimization, and machine learning techniques to solve nanolithography and general nanotechnology related problems, with a current focus on the design and fabrication techniques of exploratory nanoscale integrated circuits at the IRDS 10 nm half-pitch node (aka "2 nm node") and beyond. More recently he has increased aerospace-related research activities. He has also conducted research on control system design automation, automotive and aerospace electronics,  consumer electronics, and biomedical equipment design. His research group at the Nanoscale Design and Fabrication Systems Lab (NDFSL), Particle Beam Precision Patterning and Imaging Lab (PBPPIL), and High-Performance Servo Systems Lab (HPSSL) has been studying topics including, e.g.,

(1) Nanolithography processes and equipment: Next-generation lithography (NGL) based on multiple-charged-particle-beam-direct-write (MCPBDW), extreme ultraviolet (EUV) light, and directed self-assembly (DSA); Ion beam imaging and patterning. (2) Nanolithography software: Lithography/etching simulation, model calibration, and resolution enhancement techniques (RETs); Design for manufacturability (DFM); Charged-particle optics design optimization. (3) Nanolithography process and equipment control: Advanced process control (APC), advanced equipment control (AEC), and fault detection/classification (FDC); High-accuracy alignment and overlay algorithms; Optimal lens adjustment. (4) Circuit design automation by control and optimization techniques: Optimal design of sensor/actuator/power/computation circuits with control system perspectives. Automatic circuit/layout generation and optimization. Design for radiation hardening. (5) Sensor/actuator array systems, signal processing, and real-time control: Electron-beam position monitor system based on MEMS and sensor fusion technologies. Mixed-signal circuit design for laser interferometers. High-performance motion systems, e.g. micro laser scanning mirrors. Laser speckle reduction. ADAS sensor analysis and robustness evaluation. (6) Automotive and aerospace electronic systems: Permanent magnet synchronous motor control system analysis and design for mild hybrid vehicles. Active/semi-active suspension systems. (7) Design and control of UAV systems: Optimal design and control of electrical VTOL (eVTOL) aircraft. Control and optimization in advanced air mobility (AAM) systems.

Dr. Tsai is open to establishing new research topics based on student interests and industry demands.
