Circuit deposition

Imagine you are painting a picture, but instead of a brush, you are using a machine that sprays paint onto a canvas. Now, let's say that instead of paint, the machine sprays tiny bits of metal onto a surface to create a design. That's basically what circuit deposition is.

When we talk about circuits, we're talking about a series of wires and components that work together to make electronic devices function. Circuit deposition is the process of making these circuits by depositing (or spraying) tiny bits of metal onto a surface.

But it's not just one layer of metal. In order to make a circuit work properly, we need to deposit multiple layers of metal in specific patterns. Think of it like creating a sandwich - layering different ingredients in a certain order to make a delicious meal. The different layers of metal in a circuit are like the ingredients - each one has a specific purpose and must be placed in the right order.

To deposit the metal, we use a machine called a "deposition tool." This tool sprays tiny particles of metal onto a surface using a process called "sputtering." This is where we shoot metal ions at a solid target (like a giant chunk of metal) in a vacuum. The metal ions fly off the target and land on the surface we want to coat. We repeat this process multiple times to create the different layers of the circuit.

Overall, circuit deposition is a complex process that involves layering different metals in a specific order to create circuits that power our electronic devices. It's like creating a delicious sandwich, but instead of bread and cheese, we're using tiny particles of metal.
