CFET + GaN (Complementary FET with Gallium Nitride channels) is a forward-looking combination of vertical transistor stacking and ultra-wide-bandgap semiconductors designed to merge logic density with extreme switching speed and efficiency. While it’s still largely in the research and prototyping phase, there are several published and demonstrated examples from major semiconductor R&D groups and labs…

Microfluidic cooling is one of the most fascinating upcoming technologies for breaking through CPU thermal limits — it literally routes liquid coolant through microscopic channels inside the silicon package (or even within the silicon die itself). Here are some real-world examples and prototypes to illustrate how it works and what’s coming: 1. IBM & ETH…
