Purification, DIW Sonication, & CVD Operator

Job Summary:​

The Graphite Purification, DIW Sonication, and CVD Process Operator is responsible for preparing and processing graphite components through deionized water (DIW) sonication, high-temperature purification, and Chemical Vapor Deposition (CVD) coating. This role ensures strict adherence to standard operating procedures (SOPs), safety protocols, and quality requirements for producing high-purity, coated graphite parts used in semiconductor applications.

Key Responsibilities:

Graphite Purification Process:

• Load & unload graphite components into high-temperature purification furnaces
• Monitor furnace parameters (temperature, time, gas flow) during purification cycles
• Perform system purging and cooling steps according to recipes
• Ensure minimal contamination and proper handling of ultra-pure materials

DIW Sonication Cleaning

• Prepare graphite parts for DIW ultrasonic cleaning (pre-rinse, degrease, etc.)
• Operate ultrasonic baths with controlled time, temperature, and frequency
• Inspect parts post-sonication for residual contamination
• Maintain cleanliness of DIW system and filter integrity

CVD Coating Process

• Load graphite parts onto fixtures and into CVD reactor chambers
• Monitor recipe-driven CVD cycles (temperature, pressure, precursor gases)
• Ensure coating uniformity, thickness, and adhesion through basic inspection
• Perform post-process chamber cleaning and maintenance

Quality Control & Inspection

• Conduct visual inspection for cracks, warpage, coating defects, or contamination
• Use basic metrology tools to confirm dimensions or part condition post-process
• Prepare parts for QA team verification

Documentation & Reporting

• Accurately record batch information, process conditions, and lot traceability
• Complete run sheets, checklists, and quality logs
• Escalate process deviations or equipment abnormalities to engineers or leads

Equipment Care & Safety

• Follow all safety protocols (EHS, chemical, gas handling, PPE)
• Maintain cleanliness of process tools, chambers, and work environment
• Perform minor tool maintenance or assist with PMs under supervision
• Support continuous improvement initiatives and SOP updates

Qualifications

• HS diploma or equivalent; technical training preferred
• 1-3 years of experience in semiconductor, graphite, or coating process operations
• Basic knowledge of high-temperature furnaces, vacuum systems, and gas controls
• Familiarity with deionized water cleaning and ultrasonic systems
• Attention to detail and ability to follow strict SOPs and documentation practices
• Comfortable working in a cleanroom or controlled environments
• Team player with strong work ethic & willingness to learn complex processes
