3D Stacked Circuits: The Future of Electronics

We're building tiny skyscrapers inside our gadgets. Instead of laying computer chips out

flat, we're stacking them vertically into 3D circuits. This makes everything

way faster and more power-efficient because the signals have shorter paths. Imagine stacking

high-speed memory directly on top of a processor for zero lag. The ultimate dream

is to mix and match different chip types—logic, memory, and sensors—all in one super-compact

package. But there’s a catch: heat. The chips in the middle get incredibly

hot and are hard to cool. It’s a huge challenge, but this is the future of electronics.
