Senior Process Engineer

Department: Engineering

Employment Type: Full Time

Location: Plymouth

Description

The Thin Film Ellipsometry Process Engineer is responsible for developing, optimising, and controlling thin‑film optical measurement and characterisation processes to support high‑yield, high‑performance semiconductor device fabrication. This role focuses on ellipsometry‑based metrology for deposited thin films across development and production environments.

Key Responsibilities

• Develop, qualify, and optimise ellipsometry measurement processes for thin films (thickness, refractive index n/k, composition, and uniformity).


• Support R&D and new materials development by providing accurate thin‑film characterisation, measurement development, and data analysis.


• Own and maintain ellipsometry process recipes, optical models, and control strategies.
