Electrical Engineering at UC San Diego

From atoms to ASICs.

I've fabricated photonic and semiconductor devices at Harvard and Stanford, grown and characterized doped epitaxial films at Applied Materials, and planned a 3nm ASIC’s path to mass production at Marvell.

Cleanrooms. Stanford, Harvard, and UC San Diego.

Overview

Every stage of a chip's life.

Chips pass through many hands before they ship. I've worked at five of those stages, from simulation to production test.

  1. Simulate

    Harvard · Capasso Group

    FDTD · MATLAB

  2. Fabricate

    Stanford SNF · Harvard Mazur Group

    E-beam · RIE · DRIE

  3. Grow

    Applied Materials

    RPCVD epitaxy

  4. Measure

    Qualcomm Institute · Applied Materials

    SEM · XRD · JMP

  5. Test & ship

    Marvell

    WS · SLT · ATE · MPR

Industry

Two summers inside the semiconductor industry.

One in equipment R&D, growing and measuring epitaxial films. One in product engineering, getting a 3nm ASIC ready for volume.

Marvell Technology · Summer 2026

Taking 3nm to production.

Product Engineering Intern, Hyperscaler ASIC & Custom Compute.

  • 3nm switch ASIC
  • Wafer sort + system-level test
  • Reusable NPI template

Critical path: WS → SLT → HVM

What if

Drag a bar to delay it, or drag its right edge to change its length. Illustrative schedule, not Marvell data.

Applied Materials · Summer 2025

Finding flaws in near‑perfect crystals.

Process Engineering Intern, Silicon Epitaxy R&D.

  • XRD rocking curves & RSM
  • Python TDD calculator
  • DOE in JMP

Drag the crystal to pan. Model: Dismukes lattice constants, Matthews–Blakeslee critical thickness (the equilibrium limit; films grown at low temperature can stay strained longer), (004) rocking-curve broadening from film thickness and from dislocations via D = β²/4.35b². Dislocation density follows the typical range for SiGe grown directly on Si. Strain drawn ×10.

Research

Cleanroom research.

Four labs on two coasts, from Stanford's shared cleanroom to Harvard's photonics groups.

Harvard SEAS · Mazur Group · 2024

Twisted bilayer photonic crystals.

Stanford Nanofabrication Facility · 2022–24

Two years in Stanford's cleanroom.

Harvard SEAS · Capasso Group · 2023

Bending light the other way.

UC San Diego · Qualcomm Institute · 2024–25

Imaging devices at the nanoscale.

Try it

Twist the lattice.

In the Mazur Group, I fabricated twisted bilayer photonic crystals: two silicon nitride slabs patterned with a square lattice of holes, stacked as little as 360 nm apart. Twisting one against the other breaks their mirror symmetry, so the device transmits left- and right-handed light differently.

Our Optica paper tunes that twist with MEMS actuators, swinging circular dichroism from −0.85 to 0.64. Drag the lattice to try it.

Blue band: the device's 9°–13° MEMS range. Geometry only, not an optics simulation.

About

I'm a first-generation college student from Hayward, California. I started at Chabot College, transferred to UC San Diego to study electrical engineering, and since 2022 I've spent my summers making, measuring, and testing semiconductor devices. That range gives me a working view of the full chip lifecycle, from the cleanroom to the test floor.

Studying

B.S. in Electrical Engineering at UC San Diego, Devices and Materials depth, expected June 2028. Associate's degree in Electrical and Electronics Engineering from Chabot College. Member of IEEE and the Vietnamese Student Association.

Looking for

Summer 2027 internships in hardware, operations, and process engineering.

Long term

Semiconductors, photonics, and quantum computing. Eventually, a company of my own.

Off the clock

Weightlifting, badminton, hiking, photography, and EDM concerts.
