Abstract: A method to measure the optimal degree of horizontal tilt of wafer in photolithography process is disclosed. First, the asymmetric circuit pattern is projected on the mask with different densities onto the wafer through the projection lens to form the first image field, in which the bottom surface of the projection lens has a second image field same as the first image field. Then P1 trapezoidal beam, P2 trapezoidal beam, Q1 trapezoidal beam, Q2 trapezoidal beam, and P1' trapezoidal beam, P2' trapezoidal beam, Q1' trapezoidal beam, Q2' trapezoidal beam are irradiated to the four corners of the first image field and the second image field individually. Then the p1 hole, p2 hole, r1 hole and r2 hole on the P receiving device are used to receive the P1 trapezoidal beam, P2 trapezoidal beam, and P1' trapezoidal beam, P2' trapezoidal beam. Also, the q1 hole, q2 hold, r3 hole and r4 hole on the Q receiving device are used to receive Q1 trapezoidal beam, Q2 trapezoidal beam, Q1' trapezoidal beam, Q2' trapezoidal beam. The data obtained by the P receiving device and Q receiving device is calculated to obtain the first degree of horizontal tilt, and the P receiving device and Q receiving device are rotated for 180 DEG to obtain the second degree of horizontal tilt. The first degree of horizontal tilt and the first degree of horizontal tilt are averaged to obtain the optimal degree of horizontal tilt of wafer in photolithography process.

IPC: B65B9/22
Filed: 2002-10-03
Granted: 2005-12-21
Abstract: An object is to provide a preforming device allowing smooth travel of a packaging material (11). The preforming device includes first to fourth guides (34 to 37) for forming a web-like packaging material (11) into a tubular packaging material (11); a longitudinal sealing device (41) for longitudinally sealing the tubular packaging material (11); a drive unit; and a tube guide device (38) disposed in such a manner as to surround the tubular packaging material (11), and guiding the tubular packaging material (11) while being driven by means of the drive unit. Activation of the drive unit causes the tube guide device (38) to guide and feed the packaging material (11), thereby preventing the tube guide device (38) from resisting travel of the packaging material (11). Thus, the tube guide device (38) does not yield a braking effect, thereby allowing smooth travel of the packaging material (11). Also, high tension along the traveling direction of the packaging material (11) does not arise in the packaging material (11) when the packaging material (11) travels between the tube guide device (38) and the first or second sealing jaw device (44 or 45).

Granted: 2007-07-11
Abstract: Cyclic redundancy codes are obtained to verify the integrity of a message transmitted between a sender and a receiver. One method for obtaining a cyclic redundancy code includes separating the message into segments. Remainders are obtained for those segments based on a generator polynomial. The remainders for those segments are multiplied by a segment-constant to obtain segment-remainders for each segment. The segment-remainders are accumulated into an accumulated-remainder. The accumulated-remainder is moduled by the generator polynomial to obtain a remainder for the accumulated-remainder. The remainder for the accumulated-remainder is the cyclic redundancy code for the message.

Granted: 2004-04-11
Abstract: A semiconductor memory that reduces power consumed by a CAM. A storage circuit has stored a plurality of patterns of information indicative of whether to activate each memory word block. If specification information for specifying a predetermined pattern from among the plurality of patterns of information which has been stored in the storage circuit is input, an activation circuit activates each content addressable memory word block according to a specified pattern. If data to be retrieved is input, a specification circuit specifies a content addressable memory word which has stored data corresponding to the data to be retrieved from among a group of content addressable memory words activated by the activation circuit. As a result, activation will be performed by the content addressable memory word block. Therefore, by activating only necessary content addressable memory words, consumption of power can be reduced.
