Semiconductor wafer edge polishing system and method

摘要

An edge polishing system (20, 320) and method for edge polishing semiconductor wafers is disclosed. The system (20, 320) includes a loader (22, 326), a polisher (24, 328), an unloader (26, 330), and a controller (28, 335). The method includes the steps of loading wafers (28), and spacers (30) into a loader (22) to form a stack (36), moving the stack (36) into a polisher (24) and causing polisher (24) to polish the stack (36), then moving the stack (36) to an unloader (26), which semiautomatically removes the wafers (28) and spacers (30). The system (20) may include a controller (28) for entering the appropriate commands.
