Semiconductor Process Engineering Wet Etch & CMP

Role Overview

We are seeking a Wet Etch & Chemical Mechanical Planarisation (CMP) Process Engineer to support and develop advanced semiconductor manufacturing processes within a high‑volume wafer fabrication environment.

All experience levels will be considered however strong preference is given to candidates with significant experience and seniority, capable of operating with minimal supervision and providing technical leadership.  Experience with wet/CMP techniques is a prerequisite for this role.

The role will suit candidates from a wafer fab or semiconductor equipment vendor background, particularly those with experience in power semiconductor technologies. Experience with SiC and GaN technologies is desirable but not essential.

Key Responsibilities

• Develop and own wet etch and CMP processes in production
• Drive process stability, yield improvement, defectivity reduction, capability enhancement and cost down projects of varying scope and complexity, both as team lead or as part of a larger team
• Investigate and resolve process excursions, particle issues and reliability concerns using structured root cause analysis techniques (8D, FMEA etc)
• Lead process qualification and change management activities
• Provide technical input to new product introductions (NPI) and technology transfers
• Define and maintain process specifications, control plans, SPC methodologies and documentation
• Engage with tool vendors to progress drive tool installs and performance improvements
• Mentor and technically support junior engineers where appropriate

Required Qualifications & Experience

• Degree (or equivalent experience) in Materials Science, Chemical Engineering, Physics or related discipline
• Practical experience as a process engineer in a semiconductor wafer fab or comparable high‑tech manufacturing environment

Personal Attributes

• Strong analytical and problem‑solving skills
• Able to operate effectively in a production‑driven environment
• Comfortable working cross‑functionally and communicating with stakeholders at all levels
• Self‑driven, technically curious, and focused on continuous improvement
• Capable of balancing hands‑on engineering with longer‑term process development

Seniority & Progression

This role is open across multiple levels with the final title and responsibilities to be aligned to the successful candidate’s experience.
