A reticle is like a high-tech stencil or template used in making computer chips. Think of it as a special glass plate that contains the detailed patterns needed to create tiny electronic circuits on silicon wafers. It's similar to how a stencil helps you paint exact shapes, but at a microscopic level. In the semiconductor industry, you might also hear it called a "photomask" or "mask." These tools are crucial because they help manufacturers print the incredibly small patterns that make up modern computer chips, similar to how a negative is used in traditional photography to create pictures.
