Electro-migration in modern day electronics has been studied for many decades. Therefore, it is well known that the parameters that affect electro-migration include  conductor composition , conductor pretreatment, substrate composition, conductor configuration,  electrical bias ,  conductor spacing ,  humidity , electrolytes/electrical conductivity, gaseous pollutants, ambient air velocity, and  temperature . However, many of these studies have been performed at 600 V or less. SiC power modules have been commercially available for several years now in the 900 V – 1700 V range and have demonstrated feasibility at 3.3 kV, 6.5 kV, 10 kV, and 20 kV. Thus, it is imperative that electro-migration effects are studied at 600 V and beyond in more detail with common materials that are used to build next generation SiC power modules. Wolfspeed-Fayetteville is seeking candidates for a summer intern program with a basic understanding of electronics packaging processes, equipment, and testing. This position is a part of Wolfspeed-Fayetteville’s Modules Engineering group. Therefore, the applicant would ideally understand some of the core areas the make-up electronics packaging including: basic electronics, material science, heat transfer, fluid dynamics, semiconductor device physics, and electric circuit theory to name a few. Responsibilities Design basic test cards using CAD software with assistance from a mentor Build test cards in a class 1000 cleanroom environment Develop and conduct lab-based experiments with the assistance from a mentor and test team Acquire, plot, and analyze data with the assistance from a mentor Requirements Presently working towards an ABET accredited engineering degree Incoming Junior or higher, including graduate students Excited to be hands-on in the lab and work with a variety of different materials and processes such as wire bonding, die attach, soldering, epoxy cure, etc. Eager to work in a team environment with engineers and technicians and independently as needed Must be a good communicator Excited to learn new skills Detail oriented and able to perform multiple tasks concurrently Preferred Mechanical or Electrical Engineering background Basic CAD experience (preferably SolidWorks) Finite-element modeling experience (preferably COMSOL) Knowledge and understanding of electronics Basic knowledge of electronics reliability  Overview Since our beginning 30 years ago, we have introduced innovative and disruptive solutions that enable a more efficient, productive and safer world.
