Which under-the-radar semiconductor stocks like TSEM could ride Nvidia's coattails?

The deep research logic is organized as follows: 

Okay, let's tackle this question. The user is asking about under-the-radar semiconductor stocks, specifically mentioning Tower Semiconductor (TSEM) as an example, that could benefit from Nvidia's success. I need to find companies that are part of Nvidia's supply chain but aren't as well-known as TSMC or Intel.

First, I'll check the references provided. There's a query result (Number 10) listing TSMC and Intel as competitors, but the user is looking for others. Another query (Number 17) about Nvidia's supply chain for advanced packaging excluding TSMC, Samsung, and Intel shows no results, which means those are the main ones. However, the user mentioned TSEM, so I need to see if there's any info on TSEM in the references.

Looking through the references, Number 18, 19, 20, 21 mention Tower Semiconductor collaborating with Xscape Photonics on a laser platform for AI data centers. This ties into Nvidia's AI chip needs. Also, Number 15 mentions David Tepper investing in TSMC, which is a big player, but the user is interested in under-the-radar stocks.

Another point is the supply chain for Nvidia's Jetson Thor platform. The references mention companies like Xscape Photonics (Numbers 18, 20, 21) working with Tower Semiconductor. Since Jetson Thor is a new product, its suppliers might not be as well-known yet. Also, the references talk about Tower's silicon photonics platform, which is crucial for high-speed data centers, aligning with Nvidia's AI infrastructure.

I should also consider any partnerships or collaborations. For example, Tower Semiconductor is mentioned in the context of providing components for AI data centers, which is a key area for Nvidia. Additionally, the recent earnings (Number 19) show Tower's stock surged due to partnerships, indicating market interest.

Putting this together, Tower Semiconductor (TSEM) fits the criteria as an under-the-radar stock that's part of Nvidia's supply chain through their collaboration on photonics. There might be others, but based on the references, TSEM is the primary candidate. I'll structure the answer to highlight TSEM's role, their recent collaborations, and why they're positioned to benefit from Nvidia's growth in AI and robotics.
