    摘要: A method of grinding semiconductor wafers including simultaneously grinding both surfaces of multiple semiconductor wafers by rotating the wafers between a pair of upper and lower rotating surface plates in a state where the wafers are held on a carrier so that centers of the wafers are positioned on a circumference of a single circle, wherein a ratio of an area of a circle passing through the centers of the wafers to an area of one of the wafers is greater than or equal to 1.33 but less than 2.0; surfaces of the fixed abrasive grains comprised in the surface plates are comprised of pellets disposed in a grid-like fashion, with the pellets provided in a center portion and pellets provided in a peripheral portion being larger in size than the pellets provided in an intermediate portion.

    摘要: Chamfer correction is performed to a chamfered portion at least on a front side of a silicon wafer after an incoming inspection. Thereby, a thickness of the chamfered portion on the front side of the wafer is restored, and thus the number of reclamation cycles of the silicon wafer can be increased. In addition, the chamfered portion is not deformed even after reclamation is repeated for a plurality of times.

    摘要: In a computer system, each personal computer includes a bootup management device managing the start operation thereof. The bootup management device excludes a personal computer that failed to start, and provides a user with another personal computer. The user operates the terminal device connected to a network, and can accomplish his work whichever personal computer is connected to his terminal device. An original bootup disk image is allocated to the personal computer determined to be abnormal and it is checked whether the personal computer can operate normally or not. If the personal computer can operate normally, this personal computer is registered in the bootup management device. If unable to operate normally, the personal computer is registered and notified as needing to be maintained.

    摘要: A client device used by a user is formed by a PC as a first client and a terminal device as a second client. The terminal device is, for example, a portable type and has software capable of inputting/outputting information to/from a personal computer (PC) and being controlled at a remote place. For example, a plurality of PCs are integrated for management. Data used by the user is not stored in the terminal device side but stored in the PC side. The PC includes, for example, a sub processor and a state of the main body is monitored by the sub processor so as to detect abnormality.
