Senior Optical Scientist

Job Overview

As a Core Expert, you will be responsible for the architectural design and technical breakthroughs of DUV optical systems for semiconductor front-end metrology and inspection equipment. You will be deeply involved in the development of high-end systems such as BFI (Bright Field Inspection), DFI (Dark Field Inspection), or PMI (Phase-shift Measurement Inspection), solving industry-wide challenges including high-precision imaging, illumination, and stray light control in ultra-short wavelength bands.

Core Responsibilities

1. Architectural Design & Simulation

Lead the full-link design of imaging and illumination systems for the DUV band.

Responsible for super-diffraction-limit imaging, complex tolerance analysis, and thermal drift compensation modeling.

2. System Requirement Decomposition

Decompose full-machine metrology/inspection requirements into optical subsystems.

Define key system characteristic metrics, including wavefront aberration, distortion, and polarization etc. .

3. Core Technical R&D

Design high SNR (Signal-to-Noise Ratio) optical solutions to optimize signal quality across single or multiple modules.

Address challenges specific to DUV environments, including material selection, coating specifications, and lifetime management, ensuring long-term stability of optical modules.

Analyze and mitigate the impact of environmental perturbations on system performance fluctuations.

4. Advanced Alignment & Integration

Guide the design of precision alignment schemes for complex optical modules (e.g., co-alignment using autocollimators and interferometers).

Oversee the development of related test systems to ensure integration schemes can accurately and stably replicate Golden Tool performance.

Qualifications

Education: Ph.D. in Optical Engineering, Physics, or related fields from a prestigious university; or a Master’s degree with an exceptional engineering track record.

Experience: 8+ years in the semiconductor industry, having led the full lifecycle development of at least one DUV optical system.
