Position Summary

The Mechanical Fixture Design Engineer is responsible for designing and supporting mechanical fixtures, tooling, and handling solutions used in recoating processes and production-line parts recycle cleaning within semiconductor manufacturing. This role ensures parts can be safely stripped, cleaned, recoated, inspected, and reintroduced to high-volume production while meeting strict cleanliness, dimensional, and reliability requirements.

Key Responsibilities

Recoating & Reusable Parts Support

• Design fixtures and tooling to support:
• Parts stripping, surface preparation, and recoating processes
• Handling of quartz, ceramic, anodized aluminum, stainless steel, and coated metal parts
• Chemical cleaning
• Plasma cleaning
• Thermal bake, coating, and curing processes
• Design for multiple reuse cycles while minimizing wear, damage, and deformation

Production Line Parts Recycle & Cleaning

• Develop mechanical fixtures for:
• Wet benches, ultrasonic cleaning, mega sonic cleaning, and DI rinse processes
• Support layout and tooling design for parts recycle production lines
• Optimize fixtures for high throughput, ease of loading/unloading, and operator ergonomics
• Enable traceability through fixture design compatibility (ID marking, tagging, orientation control)

Mechanical Design & Engineering

• Create 3D CAD models and detailed 2D drawings with GD&T
• Perform tolerance analysis to ensure post recoating dimensional compliance
• Select materials compatible with:
• Aggressive chemicals (acid, alkaline, solvents)
• Cleanroom standards and EHS requirements
• Design modular and adjustable fixtures to accommodate part variation and coating thickness changes

Manufacturing, Quality & Yield Support

• Troubleshoot fixturerelated issues impacting:
• Part damage or contamination
• Support qualification of recycled parts before release to production
• Drive continuous improvement of:
• Cycle time
• Scrap reduction
• Cost of ownership for reusable parts
• Collaborate with process, equipment, quality, and EHS teams
• Interface with:
• Machine shops and fixture fabricators
• Review DFM feedback, validate first article fixtures, and support process transfer
• Manage fixture BOMs, revisions, and lifecycle documentation

Required Qualifications

• Bachelor’s degree in Mechanical Engineering or related discipline
• 3+ years of mechanical design experience, preferably in semiconductor manufacturing
• Strong CAD proficiency (SolidWorks, Creo, NX, or equivalent)
• Solid understanding of:
• Precision mechanical design and GD&T
• Surface finishing and coating impact on dimensions
• Fixture design for chemical and cleanroom environments
• Handson experience supporting production or recycle lines

Preferred Qualifications

• Direct experience with:
• Parts recycle or refurbishment programs in fabs
  • Familiarity with wafer fab parts (chambers, shields, liners, rings)
  • Knowledge of EHS and chemical handling considerations
  • Experience supporting cost reduction and sustainability initiatives
  • Exposure to LEAN or continuous improvement methodologies
• Fixture and tooling design for harsh process environments
• Strong problem solving and root cause analysis skills
• Ability to work cross functionally with production and vendors
• Attention to cleanliness, surface protection, and detail
