The present invention provides a method of mixing, in one or more container(s), magnetic or (super)paramagnetic particles with a fluid, using more than one magnets, whereby the containers are subjected to magnetic fields with different and changing directions by moving the magnets with respect to the position of the container(s) and/or by moving the containers with respect to the positions of the magnets. The invention further provided a device for doing the same.Type: GrantFiled: June 4, 2002Date of Patent: July 20, 2004Assignee: bioMerieux, B.V.Inventors: Hermanus Johannes Maria Kreuwel, Emiel Gerebern Maria Verwimp

Patent number: 6764860Abstract: An ultrasonic energy source is used to provide a variable force for measuring the binding forces between molecular entities and for sensing the presence of an analyte in a test sample. The device includes a surface that has a first binding member attached thereto and one or more particles that have a second binding member attached thereto. A reaction vessel is provided for exposing the surface to the particles whereby, if the first binding member has a binding affinity for the second binding member, a complex is formed between individual first binding members and individual second binding members and the particles thereby become immobilized with respect to the surface. The ultrasonic energy source is positioned for applying a variable ultrasonic force onto the surface, and the position of the particles is monitored as the intensity of the ultrasonic force is varied.Type: GrantFiled: January 25, 2002Date of Patent: July 20, 2004Assignee: The United States of America as represented by the Secretary of the NavyInventor: Gil U Lee

Patent number: 6764861Abstract: A method of making a high efficiency magnetic sensor for determining the presence or amount of an analyte in a test sample. The method typically includes providing a sensing device with a magnetic sensing element, exposing the sensing device to a fluid test medium suspected of containing an analyte and monitoring the resistance of the magnetic sensing element to detect any change in the electrical resistance of the magnetic sensing element in response to the immobilization of a magnetizable particle. The magnetic sensing element comprises at least one planar layer of electrically conductive ferromagnetic material having an initial state in which the material has a circular magnetic moment within the plane of the layer, a means to immobilize a magnetizable particle at a point along an axis that is perpendicular to the plane of the layer and passes through the center of the circular magnetic moment, and a means for detecting the change in the electrical resistance of each magnetic sensing element.Type: GrantFiled: October 10, 2002Date of Patent: July 20, 2004Assignee: The United States of America as represented by the Secretary of the NavyInventors: Gary A. Prinz, Michael M. Miller

Patent number: 6764862Abstract: The present invention discloses a method of forming a ferroelectric random access memory (FRAM) of a capacitor over bit-line (COB) structure. In the method, a capacitor contact plug is formed at a cell region and a stud is formed at a core region in a semiconductor substrate. An oxygen barrier pattern is formed to cover the stud. A ferroelectric capacitor comprising a lower electrode, a ferroelectric pattern, and an upper electrode is formed over the capacitor contact plug. An interlayer dielectric layer is formed over substantially the entire surface of the semiconductor substrate and patterned. Next, the interlayer dielectric layer is removed from the stud region and an interconnection contact hole is formed. A contact plug is formed in the interconnection contact hole by sputtering and simultaneously an interconnection layer is formed on the interlayer dielectric layer.Type: GrantFiled: July 17, 2002Date of Patent: July 20, 2004Assignee: Samsung Electronics Co., Ltd.Inventors: Kun-Sang Park, Moon-Sook Lee

Patent number: 6764863Abstract: The memory-storage node of the present invention includes a semiconductor substrate, a first insulating layer over the substrate, a conductive layer formed within the first insulating layer, and a barrier layer formed over the conductive layer. The barrier layer, preferably contains a ruthenium-based material, is conductively coupled with the conductive layer. The memory-storage node further includes a first electrode over the barrier layer, a dielectric layer over the first electrode, and a second electrode over the dielectric layer. The method for fabricating the memory storage-node of the present invention provides a semiconductor substrate and forms a first insulating layer on the substrate. A first opening is formed in the first insulating layer and a conductive layer is provided in the first opening. A barrier layer is then formed in the first opening and over the conductive layer. The barrier layer, preferably contains a ruthenium-based material, is conductively coupled with the conductive layer.Type: GrantFiled: March 14, 2003Date of Patent: July 20, 2004Assignee: Winbond Electonics CorporationInventors: Bor-Ru Sheu, Ming-Chung Chiang, Chung-Ming Chu, Min-Chieh Yang
