Etching Engineer

Job Description

Job Title:

Role Overview

Engineer / Senior Engineer Etching

Key Responsibilities

• Develop, optimize, and maintain

  high-yield etching processes

  for crystalline silicon and dielectric materials (e.g., SiO, AlO, HfO, TaO, TiO).
• Perform

  anisotropic silicon etching

  profile simulation and handle wafer sizes (100 mm / 150 mm / 200 mm).
• Operate and maintain

  wet etching equipment

  (Quartz/Teflon tanks, temperature-controlled baths, DI rinsing, IPA drying) and

  dry etch tools

  (RIE/ICP systems: Oxford, SPTS, Plasma-Therm, Samco, etc.).
• Work with etch chemistries:

  NaOH, KOH, TMAH, BOE, BHF, HF vapor

  and

  dry chemistries

  (CF, CHF, SF, Ar/O).
• Utilize advanced

  metrology tools

  : SEM, AFM, profilometer, ellipsometer, FTIR, XPS.
• Collaborate with cross-functional teams (Quality, Production, and R&D) to drive

  Kaizen, Lean Manufacturing, cost savings, and manpower optimization

  .
• Conduct and document

  DOE (Design of Experiments), SPC (Statistical Process Control)

  , and process capability studies (Cp, Cpk).
• Monitor and improve key performance metrics:

  OEE, OPP, PPH, FTQ, CPC, scrap cost

  .
• Prepare and maintain

  Process Flow Diagrams (PFDs), PFMEA, SOPs, and Control Plans (CPs)

  .
• Support

  internal and external audits

  by ensuring traceability, calibration records, and ISO compliance.
• Drive

  continuous improvement initiatives

  to streamline production and enhance yield.
• Ensure compliance with

  ISO 9001 / ISO 14001 / ISO 45001

  standards.

Qualifications and Experience

• Bachelors degree

  in Chemical Engineering, Mechanical Engineering, Manufacturing Engineering, or related field.

• 5–10 years of experience

  in semiconductor, MEMS, photonics, or microfabrication environments.
• Proven expertise in

  NaOH/KOH-based etching

  and wet/dry etching of silicon and dielectric materials.
• Hands-on experience with

  anisotropic silicon etching

  and wafer process handling.
• Knowledge of

  process optimization, yield improvement techniques, and Lean Manufacturing principles

  .
• Strong understanding of

  statistical analysis (DOE, SPC)

  and process capability studies.
• Familiarity with

  ISO quality and safety standards

  applicable to semiconductor manufacturing.
• Excellent

  communication, problem-solving, and cross-functional collaboration skills

  .
