Lead Tier Process Integration Engineer (2D/Monolithic)

PhantaField; Santa Clara (CA); On-site; USD 240,000 - 400,000; Full time

Job summary

PhantaField seeks a Principal Tier Process Integration Engineer to validate and optimize MoS2 tier growth on finished logic wafers while preserving wafer integrity. You will define the base back-end metal, per-tier flow, and tier isolation test vehicles, working closely with the CEO and device lead at the integration site.

You will lead thermal-history twins, assess electromigration and TDDB, and develop costed mask strategies.

Qualifications

• 12+ years of back-end-of-line or low-temperature process integration experience.
• Proven yield and defect engineering background, including defect density per layer.
• Experience with reliability checks (EM, TDDB, threshold shift) on full-flow wafers.
• Experience collaborating with a foundry or research fab as an external customer.
• Ability to write a costed, per-tier process flow and mask count.

Responsibilities

• Thermal Twin: Run full-flow logic wafers through tier steps and re-check reliability metrics.
• Back-end metal: Select base metal (W or Ru with low-k) and supplier sources.
• Tier flow: Write per-tier process flow, count masks and cost them from quotes.
• Isolation: Build tier-isolation test vehicle with injected defects.
• Defects: Measure defect density per tier against the yield model.
