Mocvd Process information

What are the key skills and qualifications needed to thrive as an MOCVD process engineer?

To thrive as an MOCVD Process Engineer, you need a strong background in materials science, chemical engineering, or physics, often with a relevant degree and experience in semiconductor fabrication. Familiarity with MOCVD (Metal Organic Chemical Vapor Deposition) equipment, process control software, and cleanroom protocols is essential, and certifications in semiconductor manufacturing can be advantageous. Strong analytical thinking, problem-solving skills, and effective communication help you optimize processes and collaborate across multidisciplinary teams. These skills and qualities are crucial for maintaining high yield, product quality, and innovation in advanced semiconductor manufacturing environments.

What are some common challenges faced by MOCVD process engineers during production scale-up, and how can they be addressed?

MO CVD Process Engineers often encounter challenges such as maintaining uniform film thickness, ensuring repeatable material quality, and managing equipment stability when moving from lab-scale to full production. Addressing these issues requires close collaboration with equipment engineers, regular process calibration, and rigorous data analysis to identify and mitigate process drifts. Continuous communication with R&D and production teams is essential to implement improvements and rapidly resolve technical bottlenecks.

What is an MOCVD process engineer?

An MOCVD Process Engineer is a specialist who operates and optimizes Metal-Organic Chemical Vapor Deposition (MOCVD) systems, which are used to grow thin films of semiconductor materials. These engineers develop and refine processes for depositing complex material layers, often for use in LEDs, lasers, or advanced electronic devices. Their work involves monitoring equipment, troubleshooting process issues, ensuring quality control, and collaborating with research and development teams to improve material performance. A strong background in materials science, chemistry, or engineering is typically required.

What is the difference between Mocvd Process vs Chemical Vapor Deposition (CVD) Technician?

AspectMocvd ProcessCVD Technician
CredentialsTechnical diploma or associate degree in electronics or materials scienceTechnical diploma or associate degree in electronics or materials science
Work EnvironmentCleanroom semiconductor fabrication facilitiesCleanroom environments in semiconductor manufacturing
Industry UsageUsed primarily in III-V compound semiconductor productionUsed across various thin-film deposition processes in semiconductor industry

The Mocvd Process and CVD Technician roles share similar credentials and work environments, often overlapping in semiconductor manufacturing. However, Mocvd Process specialists focus specifically on metal-organic chemical vapor deposition for compound semiconductors, while CVD Technicians may work with a broader range of deposition techniques. Both roles are essential in producing high-quality semiconductor devices and are frequently searched together by industry professionals.

Job description

About Indium Phosphide (InP) Technology
The world's communications infrastructure depends on semiconductor lasers, and particularly those based on indium phosphide technology. Indium phosphide lasers are engineered to emit at wavelengths that are optimal for long-distance transmission through fiber optics. In short, they enable the optical networks that form the global internet.
Coherent's broad portfolio of InP components includes application-specific Fabry-Perot lasers, directly modulated lasers (DMLs), and tunable lasers. It also includes photodiodes for high-speed receivers and power monitoring. In 2022, we introduced 200 Gbps indium phosphide electro-absorption modulated lasers (EMLs) for high-speed datacenter transceivers. This design provides our customers with the most advanced, robust, and cost-competitive laser devices for their 800G and next-gen 1.6T datacom transceiver designs. 
Our world-class and highly reliable InP technology platform is one of the very few in the industry that has been proven, with more than one hundred million lasers in the field deployed over the last decades.

The position is for support and maintenance of Aixtron G4 MOCVD reactors running InP and GaAs processes. The maintenance technician carries out routine maintenance of the reactors and all support systems, including chemical source changes, vacuum system maintenance, robotic wafer handler maintenance, chamber cleans, exhaust abatement system maintenance, troubleshooting and repair of subsystem faults. Additionally, training of other equipment technicians in these routine tasks is required.

Primary Duties & Responsibilities

The position involves supporting the MOCVD equipment engineer involving maintenance of InP-based MOCVD Aixtron growth systems. Particular emphasis is placed on following precise maintenance procedures for safe and effective repair. The technician should assume flexibility in working hours in order to ensure full communication and process compliance in support of on-shift-based technical and operations-based personnel.

  • Interaction with process engineering teams to plan and execute scheduled maintenance procedures as well as helping develop new procedures for unexpected or new failure modes.
  • Logging and tracking of machine parameters in order to detect incipient failures or deviations from normal operation
  • Participate in maintenance events, including work on gas cylinder changes, abatement column changes, process piping and plumbing requiring supplied air respirators such as SCBA and supplied air-line breathing apparatus
  • Troubleshooting: Diagnose and resolve equipment or process-related issues to minimize downtime and ensure continuous production.
  • Collaboration: Work closely with facilities and Epi process engineering to ensure safe and effective operation of MOCVD equipment
  • Documentation: train and certify on documented procedures including routine maintenance procedures, spare parts inventory, and other equipment support functions.
  • Belong to site Emergency Response Team

Education & Experience

  • AA degree with 6-10 years experience
  • SCBA certification and experience with carrying out maintenance procedures while under supplied air
  • 2 years minimum hands-on experience with maintenance and repair of complex automated semiconductor process equipment
  • 2 years minimum hands-on experience with vacuum equipment maintenance, troubleshooting and repair

Skills

  • Strong mechanical aptitude
  • Work in a systematic and organized way
  • Hands-on, roll up sleeves attitude
  • Clear and efficient communication and documentation skills
  • Team player
  • Certified or able to obtain Hazmat Technician certification

Working Conditions

  • 5 days/week, 8 hour weekday work schedule 
  • Must be able to function in a fast-paced environment, carrying out multiple projects at a time.

Physical Requirements

  • Able to work effectively in cramped conditions while wearing PPE including supplied-air breathing apparatus
  • Able to maneuver and safely handle heavy equipment
  • Able to pass yearly physical and SCBA respirator mask fit test for respiratory safety

Safety Requirements

All employees are required to follow the site EHS procedures and Coherent Corp. Corporate EHS standards.

Quality and Environmental Responsibilities

Depending on location, this position may be responsible for the execution and maintenance of the ISO 9000, 9001, 14001 and/or other applicable standards that may apply to the relevant roles and responsibilities within the Quality Management System and Environmental Management System.
