Project Title: Sample fabrication for electrical loss measurements of dielectric materials for automotive radar applications

Package Innovation within NXP CTO is a multi-national organization responsible for product technology and process development for all of NXPs semiconductor product development we design packages and simulate their electrical mechanical and thermal characteristics to ensure they will meet their desired use case technology development we are in the forefront of NXPs and often times the industrys most advanced packagesreducing to practice new ideas and new materials and bringing them to market to serve our customers process development we work in partnership with our internal assembly factories to develop the process concepts and recipes the equipment and tooling and the underlying materials and handling that enable high quality and high yield for manufacturing.

All this is accomplished with a fundamental commitment to the highest quality; deep understanding of our businesses markets products and customers; deep technical understanding of the physical systems and materials we employ; and a commitment to a smooth hand-off to our manufacturing partners both internal and external. Its all enabled by top-notch committed people spanning the globe and co-located with our businesses and factories.

Project overview:

As part of the drive towards autonomous driving and improvement of car safety NXP is striving to develop automotive radar chips with ever-increasing performance.

In the journey to become the market leader in the semiconductor industry for automotive radar chips NXPs products need to meet ever more stringent requirements related to the electrical losses of dielectric materials used in addition the electrical losses become more pronounced at the higher frequencies (100 GHz and above) which are needed for higher bandwidth in the next-generation autonomous cars with higher resolution of surrounding environment. Lowering the dielectric loss improves the performance of autonomous cars by increasing the effective range of the car radar.

At the moment within Package Innovation (R&D) in Nijmegen the main focus is on setting up and expanding the capabilities of our mm-wave lab for electrical loss addition to a network analyzer connected to frequency extenders other measurement setups include a split-block waveguide setup an open cavity resonator and probe stations.

Different types of samples are required for the measurement setups mentioned above. A close collaboration with the failure analysis department (PDC) at NXP suppliers of dielectric materials NXP labs in Austin and with Radboud University in Nijmegen are required.

Sample fabrication techniques include metal seed sputtering electroless Cu plating patterning using laser etching and grinding/polishing.

The activities are going to be focused on sample fabrication techniques and optimizing the methods to reduce/eliminate defects such as high surface roughness metal dendrites along etching lines and delamination between metal layers and dielectric material.

Activities involved in this project:

• Interfacing with internal departments at NXP and outside (suppliers Radboud University) to collaborate on dielectric sample fabrication.
• Literature study of parameters such as moisture content material aging/oxidation surface roughness what is their effect on dielectric loss
• Designing ground-signal-ground samples: dimensions measurement frequency thickness.
• Optimization of sample fabrication technique to reduce/eliminate defects.
• Design of Experiment to study effect of surface roughness moisture content and sample aging/oxidation on dielectric loss.
• Ionic analysis of chemical elements inside dielectric and die attach materials
• Measurements of thermal conductivity of die attach and liquid mold compound
• Stress-strain measurements of materials using tensile test machine
• Final report

Your profile

To be successful in this role you have:

• Studying Material Sciences such as Physics/Chemistry or equivalent study at BSc MSc level. The content and responsibilities of the internship will be adapted to the education level
• Basic understanding of semiconductors and electrical loss mechanisms in dielectric materials
• Passionate in hands-on lab-oriented environment
• Pro-active attitude in problem-solving planning and collaboration with other departments
• Detail oriented and drives for perfection with willingness to take ownership
• Strong analytical problem solving
• Effective oral and written communication and relation-skills with intercultural awareness

Duration

This is a full-time internship (40 hours per week) with a duration of 6 months or longer. The assignment could also be suitable as a thesis/graduation project. Please note that in order to be considered for an internship/working student assignment you need to be registered as a student during the entire period.
