About The Position

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.

Requirements

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

Responsibilities

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
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
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
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
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
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
