Introduction to the job

Would you like to work in a multidisciplinary team whilst providing innovative solutions to our customer’s challenges? If so, then please read on for this job opportunity!

Job Mission

As a D&E Application Engineer on YS metrology and integrated solutions for focus you will specify, design, develop and realize modules and components of solutions that fit into the plans of the business line Applications for generating wafer level dense metrology maps, enabling Focus metrology for both DUV and EUV systems.

You define and specify requirements of new functional modules in the Yieldstar and the associated litho computing platform(s). You realize detailed designs for proposed solutions within a team context and prepare for testing and roll out of this functionality after implementation. In the position you are expected to travel to customers and operate on-site for a period of one or more weeks at the time as such securing a close link with the customer environment the solutions are targeted for.

Role and responsibilities

-Working in YS Focus Applications requires a combination of knowledge and interest:
-Target design, imaging and processing knowledge to design and understand metrology target (performance)
-Optics/Physics to understand the impact of the YS optical metrology design on the Focus measurement precision and accuracy and come to new inventions to overcome limitations of the system or application
-Data analysis: invent algorithms and KPI’s to post-process the YS data towards a robust, reliable, precise and accurate Focus number
-Functional design at engineer level driving SW-based developments in a multidisciplinary agile development team.
-Generate and maintain scripts and tools for pioneering novel flows and enabling efficient troubleshooting performance providing means to step through novel flows.
-Realize improvements (technically and usability) of wafer measurements using scatterometry, this includes hardware, software and algorithm improvements of the scatterometry based metrology solutions. Manage to get the ultimate performance out of the newest (just introduced) platforms.
-Invent, design and improve solutions for wafer metrology within the framework of lithography (scanner focus measurement)
-Data and performance analysis. This with an overview of the entire value chain towards the customer. This includes the analysis of issues interfering with the accuracy of the (Focus) data.
-You will work in a young, dynamic, talented team
-Proven programming experience at expert level required in Matlab and/or Python

Education and experience

- MSc or PhD in Engineering or Physics
- Established experience in lithography, design/testof measurement systems or experimental setups in optical metrology or spectroscopy is a pre
- Customer solution orientation and affinity with the development of workflows to be implemented in Software Application solutions.
