Patent number: 5923041Abstract: Imaging instruments for inspecting products, such as semiconductor chips, are calibrated by providing a reference test structure having features which can be located by optical measurements not subject to tool-induced shift and wafer-induced shift experienced by the imaging instrument, thereby enbabling self correction of the imaging instrument. The reference test structure, which has a plurality of target units formed therein, is first qualified using the optical measurements, and is then used to calibrate the imaging instrument. The optical measurements may be made by a supplementary alternative imaging-sensor means which can be integrated into existing imaging instrument architecture. A series of test structure elements may be fabricated with one component of each being spaced at progressively greater distances from an arbitrary baseline, such that a zero overlay element may be identified by the alternative imaging sensor means.Type: GrantFiled: April 25, 1995Date of Patent: July 13, 1999Inventors: Michael William Cresswell, Loren Wendell Linholm, Richard A.

Patent number: 5920067Abstract: An improved test structure for measurement of width of conductive lines formed on substrates as performed in semiconductor fabrication, and an improved reference grid for calibrating instruments for such measurements, is formed from a monocrystalline starting material, having an insulative layer formed beneath its surface by ion implantation or the equivalent, leaving a monocrystalline layer on the surface. The monocrystalline surface layer is then processed by preferential etching to accurately define components of the test structure. The substrate can be removed from the rear side of the insulative layer to form a transparent window, such that the test structure can be inspected by transmissive-optical techniques. Measurements made using electrical and optical techniques can be correlated with other measurements, including measurements made using scanning probe microscopy.Type: GrantFiled: May 21, 1997Date of Patent: July 6, 1999Assignee: The United States of America as represented by the Secretary of CommerceInventors: Michael W.

Patent number: 5857258Abstract: A test structure for submicrometer metrology as used in integrated circuit manufacture comprises a bridge conductor divided into three segments by pairs of voltage taps. A first segment has no intermediate taps; a second segment has a number of dummy taps intermediate its ends; and a third segment has a single central tap, which may typically be formed in a different step than the remainder of the test structure, intermediate its ends. Preferably, the central tap extends from the same side of the bridge conductor as the taps at the ends of the third segment thereof. In order to evaluate a manufacturing operation, for example, to monitor the accuracy of registration of successive manufacturing steps, test signals are applied successively between the pairs of pads.Type: GrantFiled: May 12, 1994Date of Patent: January 12, 1999Assignee: The United States of America as represented by the Secretary of CommerceInventors: William B.

Patent number: 5731573Abstract: A pocket tide calculator is described which predicts tide times and moon phases in a visual display which gives the semi-diurnal tide times in any given day of the month and can be readily set for the following month. This device automatically leaves out the high or low tide which is alternately missing every 7.5 days. This invention incorporates a compressed time scale when compared with a normal 24-hour clock face which enables a concise display of the semi-diurnal tide cycle.Type: GrantFiled: May 23, 1996Date of Patent: March 24, 1998Inventors: Richard A.

Patent number: 5699282Abstract: Imaging instruments for inspecting products, such as semiconductor chips, e calibrated by providing a reference test structure having features which can be located by electrical measurements not subject to tool-induced shift and wafer-induced shift experienced by the imaging instrument, and by the imaging instrument. The reference test structure is first qualified using electrical measurements, and is then used to calibrate the imaging instrument. The electrical measurements are made by forcing a current between a plurality of spaced reference features and a pair of underlying conductors. Conductive connectors formed in vias in an insulating layer overlying the pair of conductors and individually connected to a respective conductive element formed on the insulating layer are each spaced at progressively greater distances relative to the centerline of the space between the pair of conductors, such that a null-overlay element may be identified.Type: GrantFiled: July 8, 1996Date of Patent: December 16, 1997Assignee: The United States of America as represented by the Secretary of CommerceInventors: Richard A.

The reference test structure is first qualified using electrical measurements, and is then used to calibrate the imaging instrument.

Patent number: 5598960Abstract: A foldable carrier that is mountable upon a vehicle includes rotatably connected frame, carrying, and supporting members. The carrying member is constrained for limited rotational movement relative to the frame between a carrying position and a stored position. A locking element, including a latch means and an arm means, positively locks the carrying member in its extended operational position, thus preventing collapse of the carrier after it is in use. Bicycles and other items are secured to the carrier using a tie-down system including either strap securing elements positioned on the ends of the carrying members arms or a series of mounting elements slidably positioned on the arms of the carrying member.Type: GrantFiled: June 7, 1995Date of Patent: February 4, 1997Inventors: Richard A.
