摘要:
A voice coil motor for a hard disk drive includes an inner core having an inner surface, an outer plate having an inner surface, a permanent magnet, and a coil of wire. The outer plate is positioned in spaced relation to the inner core such that a gap is defined between the inner surfaces of the inner core and the outer plate. The permanent magnet is located in the gap and attached to the inner surface of the outer plate. The coil of wire wraps around the inner core to form a solenoid coil. With such structure, the stiffness of the coil is increased. The invention also discloses a disk drive with such VCM in which the coil is directly bonded to the E-block of the hard disk drive. Therefore heat conduction of the hard disk drive is improved.

A method of manufacturing a semiconductor device that comprises forming an insulating layer over a semiconductive substrate 110 and forming a copper interconnect. Forming the interconnect includes etching an interconnect opening in the insulating layer and filling the opening with copper plating. Filling with copper plating includes using a first and second ECD. An electrolyte solution of the first and second ECD contains organic additives, and a current of the first ECD is greater than a current of the second ECD.

The disclosure regards to the porous materials, concerning a flexible 2D single-layer supramolecular polymer and its application in precise nano size separation. It comprises the synthesis of a bolaform cationic molecule, preparation of a cationic bridging stick, a flexible 2D single-layer supramolecular polymer and supramolecular polymer membrane, and the application of the membrane in precise nano-size separation. A synergetic ionic self-assembly approach which is facile, convenient and based on the ionic bond without preferential direction is used to construct a flexible 2D single-layer supramolecular polymer. Furthermore, its distinctive properties such as uniform nanoporous structure and flexibility offer an unprecedented opportunity to fabricate ultrafiltration membrane towards precise nanosize separation.

An integrated circuit structure and method of making the same is disclosed, in which the adhesion of copper conductors (12, 22) to a low-dielectric constant insulating layer (10, 16) is improved. During the fabrication of the structure, exposed surfaces of the low-k insulating layers (10, 16), including the surfaces of these layers within contact, via, or trench openings, are exposed to nitrogen gas, preferably in a sputtering chamber. An optional plasma treatment of the insulating layers (10, 16) in the presence of nitrogen gas may also be performed. As a result, the surface portions of the insulating layers (10, 16) is made to be nitrogen-rich. A liner layer (8, 21) is then formed by reactive sputtering of tantalum nitride over the nitrogen-rich surfaces of the insulating layers (10, 16), followed by the sputtering of tantalum. Copper electrodes (12, 22) are then deposited into the openings in the corresponding insulating layers (10, 16) with improved adhesion resulting.
摘要:
An apparatus and method for depositing thin films on the surface of a device such as a spherical shaped devices. The apparatus includes an enclosure containing a plurality of apertures and a conductor coil. The apertures connect to conduits for inputting and outputting the devices as well as injecting and releasing different gases and/or processing constituents. A chamber is formed within the enclosure and is configured to be coaxial with the conductor coil. Devices move through the input conduit where they are preheated by a resistance-type furnace. The preheated devices then move into the chamber where chemical precursors are added and the devices are further heated to a predefined temperature associated with the chemical precursors by radio frequency energy from the conductor coil. At this time, the gases and/or processing constituents react with the heated device thereby growing a thin film on its outer surface.
