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
- Ensure fixtures protect critical surfaces during:
- 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
- Production-line recycle flow (incoming → cleaning → inspection → recoating → qualification)
- 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 fixture related issues impacting:
- Cleaning effectiveness
- Coating uniformity
- 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
Supplier & Vendor Interaction
- Interface with:
- Recoating vendors
- Parts cleaning suppliers
- 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
- Hands on experience supporting production or recycle lines
Preferred Qualifications
- Direct experience with:
- Parts recoating (anodize, Y₂O₃, ceramic, PTFE, hard coatings)
- 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
Key Skills & Competencies
- 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
- Practical, hands on engineering mindset
