This Lego kit will allow me to build a multi-billion dollar chip factory at home.

What do all good little girls and boys want for Christmas? It's their own multi-billion-dollar chip factory. This is what I want for my Christmas present, so check out this awesome Lego kit.

You're looking at a Lego replica of an ASML Twinscan 5000. This is roughly $400 million of advanced EUV-lithography-based chip manufacturing machinery.

Intel, the company that recently demonstrated the cutting-edge device, claimed to be the first customer in the world. The Lego model has 851 pieces, and the finished model measures over a foot in length.

But it's nothing compared to the mind-blowing sophistication of the Twinscan EXE 5000. These things are so complex, we don't even know where to start.

Here's a little bit to give you a better idea of what we're up against. The machine's ultra-violet source works by firing tiny droplets of molten metal through a chamber with around 200mph, and then hitting each droplet twice with laser pulses. It's all bananas.

The Twinscan EXE 5000 is the latest lithography system. It was designed to enable chip production nodes as small as 2nm. As far as we are aware, neither Intel's upcoming node 18A nor TSMC’s upcoming node N2 use this machine. Instead, it will be used to enable nodes that succeed Intel and TSMC next-gen silicon.

This means that this machine will probably produce Intel and AMD CPUs around 2027, and Nvidia or AMD GPUs about a year later.

This kit looks like it's a lot fun, and we didn't know that the ASML store even sold it. You can get it for under $230. That's a lot for a toy, but not much for the most advanced lithography set in the world.

However, there is a catch. The fine print on the ASML Store's website is a little disappointing. It reads: "This site is for ASML employees only and requires a valid ASML e-mail address for purchase." Drat! I'm not sure if anyone works at ASML ...?
