Abstract: The footprint of a document scanning unit such as a copier, facsimile machine or document scanner or combinations thereof is reduced by causing overlap of the leading and trailing edges of long document sheets to be scanned in the document delivery roller system downstream of the scanning system (40). Differential slippage of the overlapping ends between a drive roller (54) and a pinch roller (52) is provided in a first embodiment. A second embodiment uses a moveable pinch roller (64) in the document delivery system to selectively open and close a gap to permit slippage of the leading and trailing edges of the document. A third embodiment uses three document delivery rollers (72, 74, 76) defining two spaced nips in which the leading and trailing edges of a long document are simultaneously present and a crenellated roller surface to guide the leading edge of the document to the desired nip in the delivery system (70).

Granted: 2002-08-11
Abstract: In the manufacture method of semiconductor device of this invention, an electrostatic fixation hot plate 10 in a semiconductor manufacture apparatus fixes a wafer 3 in a fashion that the fixation force increases from the central portion to the edge of the wafer. This is achieved by dividing an electrostatic fixation electrode 2 into two portions at least from the central portion 4 towards the edge direction and an applied fixation electrical force is increased gradually from the central inner portion 4 to the outer portion 5. Firstly, the fixation force is applied from the wafer center and temperature is raised. Therefore, the wafer outer portion can be induced thermal expansion easily due to the weak fixation force. This can maintain the wafer in a low stress state and thus prevent wafer breakage. Moreover, the increase of pressure and de-chuck parameters can be selected and pre-determined according to inside state of monitored wafer in advance.
