A method of machining a wafer, wherein a wafer provided with devices each having a low dielectric constant insulating film (low-k film) stacked on the face side thereof is divided into the individual devices, the devices thus divided are mounted on a wiring board, and then a grindstone is brought into contact with each of the mounted devices from the side of a side surface of the devices, to grind the back side of the device by a desired amount. Since no vertical load is exerted on the low-k film, the low-k film can be prevented from being broken, and device quality is not lowered.
