Patent number: 8387851Abstract: An apparatus for aligning a bonding tool of a die bonder with respect to a bond stage is disclosed. The apparatus comprises: a connecting member to which the bonding tool is coupleable such that the connecting member is located between the bonding tool and a main body of a die bonder; and a plurality of actuators engaged to the connecting member. In particular, the plurality of actuators are actuable to rotate the connecting member and the bonding tool relative to the main body of the die bonder about a plurality of axes, to align the bonding tool with respect to the bond stage.Type: GrantFiled: May 4, 2012Date of Patent: March 5, 2013Assignee: ASM Technology Singapore Pte. Ltd.Inventors: Chung Sheung Yung, Shing Lui Lau, Chi Ming Chong, Gary Peter Widdowson

Patent number: 7254296Abstract: An optical assembly incorporates a compact and efficient lens for coupling a beam of light from an optical device to an optical fiber. The lens includes a curved reflecting surface and a focusing surface. The lens is positioned to receive and internally reflect the beam of light from the optical device toward the focusing surface. The focusing surface in turn focuses the reflected beam into the end of an optical fiber. The curved surface may include a reflective coating for transmitting a portion of the beam toward a monitoring unit which is used to monitor a parameter of the beam. The optical assembly may further include a platform for supporting the optical device, the lens, the optical fiber and the monitoring unit.Type: GrantFiled: January 13, 2004Date of Patent: August 7, 2007Assignee: SAE Magnetics (Hong Kong) LimitedInventors: Sio Kuan Lam, Ka Suen Lee, Shing Lui Lau, Kwok Sing Cheng, Mark Wing-Keung Mak, Fuk Kay Frank Tong

Patent number: 6976832Abstract: A fluid rotary machine (10) includes an inner housing (12) provided with a manifold (68) for directing working fluid through the machine (10) and an outer housing (14) coupled to the inner housing (12) so that the outer housing (14) can rotate relative to the inner housing (12). A plurality of swinging gates (16) are supported along one longitudinal edge in corresponding sockets (38) formed along the inner circumferential surface (32) of outer housing (14). A plurality of elongated lobes (30) are supported on and evenly spaced about the inner housing (12). There is one intake port (24) and one exhaust port (26) between adjacent lobes (30). The gates (16) are biased so as to ordinarily seal against the inner housing (12). High pressure fluid enters through the inlet port (24) to a region between a lobe (30) and gate (16) causing the outer housing (14) to rotate. Eventually the gate (16) wipes across an exhaust port (26) venting the high pressure fluid through the exhaust port.Type: GrantFiled: May 30, 2000Date of Patent: December 20, 2005Assignee: Merlin Corporation Pty. Ltd.Inventors: Daryl Wheeler, Lui Lau, Ben Dyktynski

Patent number: 6468061Abstract: A rotary hydraulic machine (10) for incorporation in a drill string (92) of a well formation (86). The machine (10) is particularly adapted to act as a motor and includes an outer housing (11) of a generally cylindrical configuration having a radial inner surface (12). Rotatably mounted within the housing (11) is a shaft assembly (13) including a shaft (14) upon which a stator (15) is mounted. The stator (15) includes a plurality of lobes (16) which have a maximum radius approximately equal to the radius of the surface (12). A plurality of gates (35) are radially movably mounted in the housing (11) and engage the stator (15). The shaft (14) is hollow to provide for the delivery and the removal of hydraulic fluid to the working chambers (45 and 46) of the machine (10).Type: GrantFiled: July 16, 2001Date of Patent: October 22, 2002Assignee: Merlin Corporation Pty Ltd.Inventors: Benjamin Francis Dyktynski, Daryl Wheeler, Lui Lau

Patent number: 6315857Abstract: Polishing pads are provided for a linear chemical mechanical polishing apparatus used in manufacturing integrated circuits. The polishing pads, which are attached to a polishing belt, are grooved in patterns to advantageously transport slurry from the point of introduction to the point at which semiconductor wafers are polished. The patterns include at least one set of multiple parallel grooves extending across the polishing pads. The grooves form an angle with the direction of travel of the belt that is unequal to zero.Type: GrantFiled: July 10, 1998Date of Patent: November 13, 2001Assignee: Mosel Vitelic, Inc.Inventors: Tsungnan Cheng, Ethan C. Wilson, Shou-sung Chang, Gregory C. Lee, Huey M. Tzeng, David E. Weldon, Linh X. Can, Luis Lau, Siyuan Yang
