Introduction to the job

EUV lithography systems enable our customers to create next generation consumer electronics (like smartphones, tablets, etc.). For this the EUV lithography system needs a push towards an industrialized product so our customers can use it in a profitable way. A major part of this is to improve the defectivity performance of the EUV systems. As part of the Defectivity department you will work in multidisciplinary teams driving product development step by step. The holder of this position is reporting to the Pellicle & DGLm (Film) Design Group Lead.

The main function of a pellicle is to increase the defectivity performance of an EUV scanner without having negative impact on other performance parameters. The main function of DGL membrane is to improve spectral purity of the EUV beam before it hits the wafer. Both products are extremely thin membranes consisting of several layers. They are used on all EUV scanner platforms. Both the material stack composition and the way of processing of the pellicle are important to meet the product performance as defined for the various generations of membranes.

Role and responsibilities

  • Develop analysis/characterization methods to measure/analyze thin membranes (EUV pellicle) films in several phases of off-line and in scanner testing
  • Develops and defines off-line and in EUV scanner testing. Reporting on results and analysis
  • Uses the different test and analysis results to form a picture (model) of the pellicle material change mechanisms during scanner usage
  • Contribute to the selection and qualification of pellicle stack materials
  • Supports the specification of the pellicle film layers for the next pellicle film generations
  • Contribute to the testing and qualification of (next) pellicle film generations
  • Develop next generation pellicles with a multi-disciplinary team in a fast changing environment
  • Achieves results by literature search, experimental testing or supervision of external activities.
