摘要:
A chip mounting plate construction of lead frames for semiconductor packages which provides a chip mounting plate having a greatly reduced area to obtain a small bonding area between the chip mounting plate and a semiconductor chip mounted on the chip mounting plate, thereby capable of minimizing thermal strain generated at the chip mounting plate due to a thermal expansion thereof. The chip mounting plate is constructed to have a smaller area than the semiconductor chip, to have a central opening, or to have recesses.

An uplink feedback channel reporting method is disclosed for using the primary and secondary fast feedback channels to efficiently report the channel quality, MIMO feedback, and CQI types of data from a mobile station to a base station. The reporting method reports regular information periodically and non-regular information on demand.

摘要:
Described herein are semiconductor device packages with EMI shielding and related methods. In one embodiment, a semiconductor device package includes: (1) a substrate unit including a grounding element disposed adjacent to a periphery of the substrate unit and at least partially extending between an upper surface and a lower surface of the substrate unit; (2) a semiconductor device disposed adjacent to the upper surface of the substrate unit; (3) a package body disposed adjacent to the upper surface of the substrate unit and covering the semiconductor device; and (4) an EMI shield disposed adjacent to exterior surfaces of the package body. A periphery of the package body is laterally recessed, such that a connection surface of the grounding element is electrically exposed and electrically connected to the EMI shield. The grounding element provides an electrical pathway to ground electromagnetic emissions incident upon the EMI shield.

摘要:
The present invention relates to a carbon nanotube transistor biosensor with aptamers and a method for detecting a target material using the same, more particularly to a carbon nanotube transistor biosensor recognizing the target material, i.e., a specific molecule (such as a protein, a peptide, an amino acid, and an organic/inorganic compound) by using DNA aptamers and a method for screening a target material using the same. In the biosensor of the present invention, the aptamers binding specifically to a particular protein are adsorbed on a carbon nanotube constituting the channel domain of carbon nanotube transistor to easily detect/identify a particular protein via the electric conductivity of carbon nanotube that varies if the particular protein is exposed to corresponding aptamers.

An LED having vertical topology and a method of making the same is capable of improving a luminous efficiency and reliability, and is also capable of achieving mass productivity. The method includes forming a semiconductor layer on a substrate; forming a first electrode on the semiconductor layer; forming a supporting layer on the first electrode; generating an acoustic stress wave at the interface between the substrate and semiconductor layer, thereby separating the substrate from the semiconductor layer; and forming a second electrode on the semiconductor layer exposed by the separation of the substrate.
摘要:
A guidewire has a proximal portion and a distal portion. The distal portion may be coated, as with a hydrophilic or other coating, or may be uncoated. The proximal portion, however, is coated with a specially lubricious coating that serves to reduce resistance and to prevent lock up as the guidewire moves through a guiding catheter. The proximal portion may, for example, be coated with a base layer, such as TEFLON® (polytetrafluoroethylene), and one or more top layers, such as a silicone-based layer. In one approach, two silicone-based top layers are applied. Alternatively, a top layer of spray PTFE, paraffins, olefins, and/or fats may be applied. As an alternative, the base layer may be optional, such that the top layer or layers is coated onto bare metal, or a base other than TEFLON® may be used.
摘要:
A method for controlling the hydrophilic droplet using the electrowetting principle is disclosed. More specifically, the present invention provides a method for increasing the change of the contact angle in the interface that is formed between the hydrophilic droplet and the nonpolar fluid by adding a constant concentration of two-element electrolyte or three-element electrolyte to the hydrophilic droplet; and an apparatus for controlling the droplet having the change of the contact angle and velocity scope increased by the method.

An energy absorber for an automobile front-bumper, in which the energy absorber is mounted on the inner side of the automobile front-bumper to absorb impact. The energy absorber includes a central part, and comer parts each positioned at the left and right sides of the central part, wherein the central part is fabricated to be thicker than the comer parts using resin foam foamed with a high magnification, and the comer parts is fabricated to be thinner than the central part using resin foam foamed with a low magnification, thereby increasing the impact absorption effect and the rigidity of the energy absorber.
