No, your CPU is made from the top-down, via lithographic techniques.

The silicon wafers are grown from the bottom-up, but silicon is as chemically simple as it gets -- a pure element!

LK99 would be tougher to grow (correctly, and assuming that there is a specific superconducting configuration from among several semiconducting configurations,) by at least several orders of magnitude. Growing pristine crystals of such a complex and entropic material is something that has never been attempted.

They did show a thin film sample in their paper, where they show the superconductivity measurement setup. They even mention it is a thin film sample of the material. looks transparent on the probing station. That is what they measured for superconductivity, not the rock/ingot form. That seems to be only a sort of magnetic demo for the material, nothing more. But the superconductive applications material seems to be thin film tech, as they state in their original paper.
