Principal Process Engineer, 2D Growth

PhantaField; Santa Clara (CA); In loco; USD 180.000 - 290.000; Tempo pieno

Descrizione del lavoro

PhantaField in Santa Clara, CA invites aSenior scientist to lead PP-MOCVD process development and to build evidence packages for crystalline MoS2 at sub-450°C. You will own growth recipes and plan wafer-level demonstrations, reporting to the CEO and coordinating with growth and applications teams.

The role demands a PhD and 8+ years in TMD MOCVD or CVD, plus hands-on experience with metal-organic precursors, Raman/PL/XPS data, and DOE/metrology planning.

Competenze

• PhD required in materials science, chemistry, physics or electrical engineering.
• 8+ years of process development in TMD MOCVD or CVD, or ALD.
• Experience with DOE and SPC on pilot or production tools.
• Experience handling metal-organic precursors and toxic gases such as H2S and H2Se.

Mansioni

• Build the evidence package with Raman, PL and XPS data from controlled runs.
• Run DOEs on plasma, UV and temperature and optimize precursor injection.
• Develop MoS2 recipes, then WSe2, and demonstrate wafers to customers.
• Write the metrology plan and define acceptance data for FAT and customers.
• Coordinate growth runs on memory/logic test wafers with engineers.

Lead PP-MOCVD process development and build the evidence for crystalline MoS2

About us

NanoGalaxy is PhantaField's growth tool. It uses pulsed-plasma MOCVD (PP-MOCVD) and is designed to grow 2D semiconductors such as MoS2 on 300 mm wafers below about 450 °C, so that new layers can be grown on top of chips that are already finished. We designed and ran an 8-inch research reactor with a university partner, and we have designed the 300 mm system. Measured results so far include MoS2 transistors and a capacitor-less 2T0C memory cell that holds data past 1,000 seconds. Prof. Chenming Hu, co-inventor of the FinFET, was our first investor and advises us.

The role

You will own the growth process. The first job is a data set nobody can argue with: crystalline monolayer MoS2 grown below about 450 °C, shown with full-range Raman, PL and XPS, from runs under our control with clean records. From there you build the recipes and demo wafers customers will judge the tool by. You also plan growth runs on PhantaField's own memory and logic test wafers. You report to the CEO and lead process and applications.

What you'll do

• EVIDENCE Build the evidence package: Raman over 10–1,800 cm⁻¹, photoluminescence and XPS, with TEM and SIMS from outside labs.
• DOE Run DOEs on plasma, UV and temperature, including a redesigned path for injecting the metal precursor.
• RECIPES Develop MoS2 recipes first, then WSe2, and make the demo wafers prospects ask for.
• METROLOGY Write the metrology plan and the acceptance data set a customer and a FAT will use.
• DEVICE WAFERS Plan and coordinate growth runs on PhantaField's own memory and logic test wafers with the engineers who design them.

What we're looking for

• PhD in materials science, chemistry, physics or electrical engineering
• 8+ years of process development in TMD MOCVD or CVD, or in ALD
• DOE and SPC on a pilot or production tool
• Safe hands‑on work with metal‑organic precursors and toxic gases such as H2S and H2Se
• Reading Raman, PL, XPS and AFM data on 2D films well enough to defend a claim of crystallinity
• Run records and data labeling someone else can audit

Nice to have

• BEOL thermal-budget integration on finished wafers
• Applications work at an equipment maker
• WSe2 or other p‑type 2D growth
• Plasma‑ or UV‑assisted deposition

Why PhantaField

Everything we do depends on growing good 2D layers at low temperature on large wafers. You own that process, you have a principal's say in how the tool is built around it, and your data decides what we tell customers.
