What is one major lesson you have learned from a past failure or setback in your work with semiconductors? How has this experience shaped your approach?

While semiconductors haven't been a direct focus area in my career, the principle of navigating failures applies universally across industries. I recall working with a startup aiming to revolutionize a technical niche—not semiconductors specifically, but similarly complex and fast-paced. They spent an incredible amount of time perfecting their product but ignored early customer validation. By the time they were ready to launch, the market had shifted slightly, and their innovation didn't align with demand anymore. I felt the sting of that failure alongside them; it was a wake-up call about the importance of iteration and customer alignment from day one. This experience has deeply influenced how we approach strategic decisions at spectup. No matter how groundbreaking a technology or concept may seem, we now insist on constant interaction with customers and stakeholders to ensure alignment. One of our biggest priorities is helping startups avoid the "build it and they will come" fallacy. If I've learned anything, it's that your market can surprise you—sometimes positively, sometimes negatively—but you can't afford to stay in the dark. That hard lesson taught me that failure isn't final; it's feedback. And now, with every client we work with, we're relentless in crafting business strategies that embrace adaptability and real-world input at every stage.

One major lesson I learned from a past setback in semiconductor work was during a yield drop caused by a malfunctioning etching machine. Initially, the failure analysis was slow because traditional diagnostic methods couldn't isolate the root cause quickly due to the increasing complexity of the device architecture. This experience highlighted the limitations of relying solely on conventional failure analysis techniques for advanced semiconductor processes. It shaped my approach to prioritize a systematic, data-driven root cause analysis combined with cross-functional collaboration. We integrated equipment diagnostics, process log reviews, and recalibrated tools, which improved yield by 20%. More importantly, it taught me the critical need for proactive failure analysis strategies, incorporating design-for-test and embedded diagnostics early in development to keep pace with evolving chip complexity and avoid costly delays.
