半導体ウェーハボートとは？ 材質、構造、および用途

In semiconductor manufacturing, wafers must be processed, transported, heated and cooled under highly controlled conditions. During high-temperature processes such as diffusion, oxidation, annealing and LPCVD, wafers cannot simply be placed directly inside a furnace. They need a stable, clean and precisely designed carrier to hold them in position. This carrier is commonly known as a semiconductor wafer boat. A wafer boat may look like a simple supporting fixture, but it plays an important role in process stability, wafer cleanliness and production yield. The choice of wafer boat material, structure and dimensional accuracy can directly affect thermal uniformity, particle control, wafer spacing and long-term equipment reliability.
