Day 1 on the Semiconductor Process Engineer path.

What a Semiconductor Process Engineer does

Improves chip-making steps in a factory so devices meet specs, run reliably, and are produced with high yield.

  • Design and tune process steps to hit electrical and physical targets
  • Analyze yield and defect data to find root causes of failures
  • Run experiments to compare settings, materials, and equipment recipes
  • Write and maintain process specs, control plans, and work instructions
  • Partner with equipment teams to qualify tools and reduce downtime
  • Monitor process health using charts and alarms, then act on drifts
  • Support production issues with fast troubleshooting and containment

A day in the life

  1. Review overnight yield, defect maps, and tool alarms; pick top issues
  2. Meet with production and equipment teams to plan tests and priorities
  3. Run DOE or split lots, then inspect results and update process limits
  4. Document changes, train operators, and hand off actions to next shift

Tools you will use

Data analysis: Python, JMP, MinitabSpreadsheets: Excel, Google SheetsStatistical process control: control charts, Cp CpkMetrology: SEM, ellipsometry, profilometryDefect inspection: optical inspection, defect reviewDocumentation: SOPs, change controlManufacturing systems: MES, SPC dashboards
