Meta to Intel Corporation: From Process Development to Advanced Packaging
After working extensively on slant etching, particularly on silicon carbide technology used in Meta’s Orion (also featured in Meta’s [formerly Facebook's] engineering blog), I expanded my work at Intel into photolithography, far-back-end (FBEOL) processes, and advanced packaging.
I became particularly interested in advanced packaging and heterogeneous integration because I saw them as essential technologies for enabling both high performance and miniaturization in devices such as AR glasses. This is why I moved to Intel Corporation. I wanted to see a different side of the industry. AR glasses need to pack significant computing capability and functionality into an extremely small form factor. This requires integrating multiple chips and different types of devices at high density involving micro bumping, hybrid bonding, and memory stacking is required for. I came to see advanced packaging itself as a critical technology for achieving augmented reality glasses
As I took on greater technical responsibilities, my perspective on semiconductor manufacturing also evolved. One of the most important lessons I learned was that there is a significant difference between developing a process and ramping that process into high-volume manufacturing and scaling it into a mature, stable production process.
Through this experience, I developed a broader perspective—not only on individual process technologies, but also on what it takes to transform a promising technology into a reliable manufacturing process at scale.
"I remember entering Semicon Taiwan not knowing anything, and from that experience, wanting to do anything to get into the semiconductor industry, to understand what is going on.
I actually interviewed for the Facebook Reality Labs Position while I was in Taiwan and since there was a time difference, the interview was done in the middle of the night."
I still had the dream of living in Japan and doing semiconductor engineering. To return to the place where I had the opportunity to grow up during my formative years of my youth. I majored in Material Science, and knew Japanese and English and had a connection to Taiwan. Through reaching out through LinkedIn to a friend, I was able to secure at job at TSMC Fab23, Japan Advanced Semiconductor Manufacturing doing Semiconductor Materials Quality and Reliability and managing supplier material quality. It was a dream job for me to be joining a company that represents the semiconductor industry.
Intel corporation was a wonderful place to learn and gain valuable experience. It took me three separate interviews for different job positions to finally enter Intel Corporation. I had the opportunity to fix complicated lithography exposure tools, something I would have never thought I would do in the future during my University years.
I then moved on to SPC and Process Control Analysis management for the Far back end lithography module. My world was in microns being in Far Back End. To connect the chip to the circuitboard we cannot possibly have nanometer sized connections. I always wondered what the front end, FEOL was like. To me it was a place of mystery.
Looking back I enjoyed my time at Intel and I gained many valuable engineering skills and a problem solving mindset.
