Senior Plasma/RF and UV Source Engineer

PhantaField; Santa Clara (CA); Presencial; USD 160 000 - 260 000; Tempo integral

Resumo da oferta

PhantaField in Santa Clara, CA, is seeking a senior plasma and RF engineer to characterize and redesign the plasma and UV sources on the NanoGalaxy growth tool. You will measure plasma with optical diagnostics, run UV wavelength studies, and redesign both sources in-house under the CEO, guiding product direction.

This role requires 8+ years in plasma source and RF engineering for semiconductor equipment, experience with 13.56 MHz generators, matching networks, and pulsed RF, plus hands-on

Qualificações

• 8+ years of plasma source and RF engineering for semiconductor equipment.
• 13.56 MHz generators, matching networks and pulsed RF.
• Plasma diagnostics: optical emission spectroscopy and Langmuir or other probes.
• You design, run and write up your own experiments.
• RF safety and interlock design.

Responsabilidades

• Characterize plasma with OES and probes and decide precursor injection.
• UV study: equal-photon-fluence action-spectrum study across 222-405 nm.
• Replace the ring UV source with a graded line source and closed-loop flux control.
• RF: size the RF generator and match, and design the pulsed RF bias.
• Design the purged UV enclosure and the RF interlocks.

Descrição da oferta de emprego

Characterize and redesign the plasma and UV sources on a 300 mm growth tool

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

Our process uses both a plasma and UV light. Which one does what, and where the precursor should meet each, decides the production design. You will measure the plasma, run the UV wavelength study, and redesign both sources from what you find. The sources are core to the tool, so this work stays in-house. You report to the CEO.

What you'll do

PLASMA Characterize the inductively coupled plasma with OES and probes, and choose between remote and coil-referenced precursor injection.

UV STUDY Run an equal-photon-fluence action-spectrum study across 222-405 nm.

UV SOURCE Replace the ring UV source with a graded line source and closed-loop flux control.

RF Size the RF generator and match, and design the pulsed-RF bias.

SAFETY Design the purged UV enclosure and the RF interlocks.

What we're looking for

• 8+ years of plasma source and RF engineering for semiconductor equipment
• 13.56 MHz generators, matching networks and pulsed RF
• Plasma diagnostics: optical emission spectroscopy and Langmuir or other probes
• You design, run and write up your own experiments
• RF safety and interlock design

Nice to have

• UV and excimer optics
• Photochemistry of metal-organic precursors
• Plasma modeling
• Plasma sources for ALD or CVD

Why PhantaField

This is physics with a direct line to a product decision. Your measurements set the source architecture before design freeze, and you build what you specify.

PhantaField is an equal opportunity employer. This role involves technology subject to U.S. export controls. Employment may depend on obtaining any required U.S. government authorization.
