ChIP-on-chip

Chip-on-chip, sometimes referred to as "CoC," is a technique used in electronics to stick one computer "chip" on top of another one. Imagine having two pancakes, but instead of putting butter or syrup in between them, we glue them together. This is similar to how chip-on-chip works, but instead of butter or syrup, we use a special glue called "epoxy."

Why would we want to put one chip on top of another? Well, sometimes a computer needs to have multiple chips working together to do a task. But if we just put them next to each other, it takes up a lot of space. By stacking them using chip-on-chip, we save space and make the computer more efficient.

The process of chip-on-chip involves a lot of technical steps. First, we need to clean the surface of the chip so that the epoxy glue can stick properly. Then, we apply the epoxy and let it dry. Once it's dry, we can place the second chip on top and press down gently to make sure it's securely attached.

The chips need to be placed very precisely on top of each other to work correctly. This is done using something called "alignment marks," which are little markers on each chip that help us line them up perfectly.

Chip-on-chip is a very important technique in modern electronics, especially in things like smartphones and computers where space is at a premium. It allows us to fit more computing power into a smaller area, making our devices faster and more powerful.
