Research Experience
Programming a NAND flash string in TCAD, from FN tunneling to hot-carrier injection
Sep 2026 – PresentTeam of six
- Built a 7-gate SONOS NAND string in Sentaurus, got program, erase and ISPP working with FN tunneling, and am now reproducing a published hot-carrier programming scheme on it.
- Simulated program, erase and ISPP on a 7-gate SONOS NAND string in Sentaurus TCAD (nonlocal tunneling, charge-trap layer traps).
- Compared planar and cylindrical (gate-all-around) solutions of the same stack; the cylindrical cell showed about twice the threshold shift (+7.10 V vs +3.48 V at 20 V, 100 µs).
- Reproducing the bilateral hot-carrier programming scheme of Kim et al. and tracking why injection into the trap layer does not yet appear.

How one grain boundary changes a capacitorless DRAM cell
Sep 2026 – PresentTeam project, Semiconductor Device Design Lab course
- In simulation, a single grain boundary in the poly-Si channel cut the sensing margin of a 1T-DRAM cell by 27%, close to the 25% reported in the literature.
- Simulated a poly-Si capacitorless DRAM (1T-DRAM) cell in Sentaurus TCAD and varied the position and trap density of a grain boundary in the channel.
- Wrote Python scripts to generate Workbench experiment tables (47 DC and 37 memory runs) and to export read currents from transient results.

Designing an 8×8 SRAM from the cell up
Sep 2026 – PresentTeam of six, semiconductor design club
- A 64-bit 6T SRAM with precharge, row decoder, write drivers and sense amplifiers; all 64 cells pass write-then-read in simulation.
- Designed a 6T SRAM cell and an 8×8 array with precharge, 3-to-8 row decoder, write drivers and latch-type sense amplifiers in Cadence Virtuoso.
- Sized the cell by sweeping 507 width combinations in Spectre with scripted pass/fail checks for write, read disturb and read differential voltage.
- Verified the full array in simulation (64 of 64 cells pass write-then-read); layout and tape-out are the next stage.

A CMOS test chip, from layout to probe station
Mar 2026 – Jun 2026Team of five, Integrated Circuit Process Lab course
- Designed a 2 cm × 2 cm test chip with nine structure types, ran lithography and etch experiments in the cleanroom, and extracted contact resistance and threshold voltage from fabricated devices.
- Laid out a 2 cm × 2 cm CMOS test chip in KLayout (TLM, NMOS/PMOS, inverter, NAND/NOR, three SR-latch variants) under λ = 5 µm design rules.
- Ran a maskless-lithography dose test (optimum 50 mJ/cm² for 1 µm resist) and CF₄/O₂ RIE experiments in the cleanroom.
- Measured fabricated devices on a probe station; extracted contact resistance by TLM (71.9 Ω n-type, 49.4 Ω p-type) and NMOS threshold voltage by the gm-max method (2.01 V).

Edge UAV for real-time pothole detection
Sep 2025 – Feb 2026Team of five · drone platform and camera input
- A quadcopter that spots a pothole on its own, stops over it, and sends the photo, GPS position and a risk level to a web map.
- Owned the drone side of a five-person project: flight platform, camera mounting and the image input feeding onboard detection.
- Team trained YOLOv8 on 5,396 images (mAP 0.898 after relabelling) and deployed it on a Jetson Orin Nano with TensorRT (FP16).
- Detection triggers a MAVLink BRAKE command to the Pixhawk; the event (image, GPS, altitude, risk level) is uploaded to a Flask-based web map.
- Co-author of a paper submitted to JCCI 2026.
