GLOBALFOUNDRIES
June 2021 - May 2022
GlobalFoundries is a worldwide semiconductor manufacturer, producing integrated circuits for everything from Apple Pay chips to control modules for US missiles. I interned at FAB10 in East Fishkill, New York, where I worked on projects involving robotic task automation and facilities mapping.
Skills:
- Semiconductor Manufacturing
- OpenCV
- MS Power Automate
- LIDAR Mapping
SAHD Documentation
After maintenance, clean room capsules may be contaminated. Instead of immediately processing a full FOUP (25 wafers, each worth up to $20k), a smaller number of wafers are broken out and processed, in a "send ahead" (SAHD). Breaking normal automation routines is a very complex, manual task and not well documented. I worked with teams in many different tool areas to record how each executes SAHDs.
Robotic Process Automation
The next step was to build and deploy bots to complete SAHDs with a single button click. I developed WIP lookup bots in MS Power Automate that streamlined searching for a suitable SAHD candidate, and others that notified the appropriate personnel when a SAHD was complete. These alone were anticipated to save 500 personnel hours per year, and up to 4000 hours of machine downtime caused by successful SAHD tests that teams forget to close out.

CV Inspection Code
I optimized computer vision code for measuring V-grooves in silicon photonics wafers by profiling code performance and parallelizing non-dependent tasks. This led to an 87% increase in throughput of wafers inspected.
Facilities Mapping
I conducted LIDAR scans of facilities using Intel RealSense cameras and Dot3D for planning and maintenance training purposes. I also completed a project started by summer graduate interns to create a 360 VR tour of FAB7, using Adobe Premiere Pro.
