Backend
In semiconductor manufacturing, the "Backend" refers to the final stages of making computer chips, after the main circuits have been created. It involves packaging and testing the chips to make them ready for use in electronic devices. Think of it like the final assembly and quality control in a factory - where the product gets its protective covering and is thoroughly checked before shipping. This is different from "Frontend" processes, which involve creating the actual circuits on silicon wafers. The term "Backend" might also appear as "Back-end" or "Back End" in job descriptions.
