Emerging memory pathfinding: - Emerging memory pathfinding including architecture, device and material, Plan emerging memory technologies (3D Xpoint, NAND, MRAM, RRAM) to fit into organization's product roadmap. - Designed pre-Si device specifications based on TCAD and partial experimental data allowing tape-out 3rd gen of 3DxP technology. - Identified root cause and developed fundamental solutions for reliability limiters of Optane memory cell.

Non-volatile memory R&D for 1st and 2nd gen Optane SSD and persistent memory (storage class memory). - Innovated cell structure/material, write & read algorithm enabling the 1st die yield and continuous yield/reliability improvement. - Key inventor for core memory IPs. - Applied advanced statistics and machine learning for fast TD decisions and high volume manufacturing variation control.

Projects: 1. Non-planar tri-gate InGaAs quantum well high electron mobility transistors (HEMTs) 2. Low power InGaAs single electron transistors (SETs) 3. Device model development for low sub-threshold swing tunnel field-effect-transistors (TFETs)

• Process optimization of MOCVD high-k dielectric deposition on III-V semiconductors - Characterized the MOS capacitors with high-k (HfO2/Al2O3) grown under various conditions in MOCVD chamber. Optimized deposition process based on interface trap density measurements
