Somewhat out of the blue, Silicon Box has announced the opening of its US$2 billion semiconductor assembly plant in Singapore. The "startup" is founded by several of Marvell's founders, suggesting the company has the right pedigree to compete in what is sure to be a very competitive market over the next few years. Silicon Box is not a foundry and will at least at this point in time, not be involved in foundry services, but instead the company will focus on advanced chip packaging technologies, focusing on chiplets.

The company is promising "faster time-to-market, lower new device design cost" on its very rudimentary website, something the company has yet to prove to be capable of. However, its new plant in Singapore covers 73,000 square metres and is said to feature state of the art production equipment for turning chiplets into chips. The factory is said to create some 1,200 jobs in Singapore, suggesting that this is a company that means business. According to a comment by company founder and CEO BJ Han to Reuters, "customers had been lining up" since before the completion of the assembly plant. Silicon Box is expecting to have several AI chipset companies as its customers, including Tenstorrent, which so far is the only officially mentioned client. Time will tell if Silicon Box can compete with established chip packaging businesses and if they can deliver on their promise to be faster and cheaper than the competition.
