Abstract: A semiconductor device has a substrate of one type of semiconductor material, such as silicon. A contact structure is formed on the substrate, and the contact structure is formed of a compound of a metal and a second type of semiconductor material, such as germanium. The contact structure according to embodiments of the present invention include a semiconductor material which a different semiconductor material forming the substrate. Higher or lower barrier height is obtained by embodiment of the invention. A method for forming a contact structure in which a substrate of one type of semiconductor material is provided. A layer of another different semiconductor material is formed on the substrate. A layer of metal is then formed on the layer of the other different semiconductor material. Upon annealing, a contact structure is formed on the substrate, which is a compound of the metal and the other different semiconductor material, onto the substrate.

Abstract: The present invention provides a medical supply monitoring and tracking system (100). In one embodiment, the system (100) includes a medicine trolley (300). A storage compartment (312,314,316) of the medicine trolley (300) has two RFID antennae (340) aligned substantially orthogonal to each other for monitoring a RFID tag (360) on each medical supply (350). In another embodiment, the system (100) also includes a communication device (210) and a staff identification card (222). The communication device (210) includes a functional module, each relevant for a doctor (223), a nurse (225), a pharmacist (224), and so on.

Abstract: The present invention provides a storage shelf (312,314,316) in a RFID tracking system (100). In one embodiment, the storage shelf (312,314,316) is on a medical supply trolley (300). Each storage shelf (312,314,316) has two RFID antennae (340a, 340b) that are aligned substantially orthogonal to each other. Each RFID antenna (340) is tuned to a resonant frequency, and with a bandwidth below and above the resonant frequency. The bandwidth defines a Q factor such that the antenna (340) is insensitive to a conductor placed near the antenna (340).

Abstract: A stepping motor for generating vibration is provided and includes a stator and a rotor. The rotor includes a shaft, a ring magnet and a rotor frame, and the rotor frame is formed into a substantial cup-shape including a disk portion having an opening at the center and also including a cylindrical portion continuously arranged at the periphery of the disk portion, and a weight portion is arranged in a portion of the rotor frame so that the gravity center of the rotor frame an be located at a position eccentric with respect to the center of the rotor frame.

Abstract: A method of optically inspecting a fastener to determine whether it meets two or more dimensional parameters is provided. The method includes using centrifugal force to place the fastener in a predetermined location. Two or more sets of image data of the fastener are generated from two or more corresponding different angles. Fastener pass/fail data is generated using a dimensional requirement associated with each set of image data.
