Title: Semiconductor wafer and method for manufacturing semiconductor device
Inventor: ITO FUYUMA
IPC: H01L21/306
Filed: 2020-09-15
Abstract: To provide a semiconductor wafer with a larger surface area, and a method for manufacturing a semiconductor device.SOLUTION: A semiconductor wafer 1 includes a surface 10a having a groove 11 including an inner wall surface 11a. The inner wall surface includes a recess 11c. The inner wall surface is exposed from the groove. At least one semiconductor wafer 1 is carried into a processing chamber of a semiconductor manufacturing device together with a plurality of device wafers, and similar processing is performed. This makes it possible to use the semiconductor wafer 1 as a dummy wafer if desired processing results cannot be obtained at a specific position in the processing chamber. The semiconductor wafer 1 is formed with a plurality of grooves 11 so that a surface area increases. For this reason, the semiconductor wafer becomes a dummy wafer having the same surface area as the device wafer. Therefore, disposition variation in the processing chamber caused by a difference between surface areas can be more reduced, thereby making it possible to improve uniformity of film thickness, film composition, and film density and the like between device wafers or in a plane of a device wafer 9.SELECTED DRAWING: Figure 2
