Abstract:
A high frequency IC package mainly includes a substrate, a bumped chip, and a plurality of conductive fillers where the substrate has a plurality of bump holes penetrating from the top surface to the bottom surface. The active surface of the chip is attached to the top surface of the substrate in a manner that the bumps are inserted into the bump holes respectively. The conductive fillers are formed in the bump holes to electrically connect the bumps to the circuit layer of the substrate. The high frequency IC package has a shorter electrical path and a thinner package thickness.
Abstract:
This invention provides a donor bead for use in an assay, wherein the bead (a) is coated with a layer of hydrogel having directly or indirectly bound thereto a polyacrylamide-supported sugar or a polyacrylamide-supported glycan, and (b) comprises a photosensitizer which, upon excitation by laser light of a suitable wavelength, converts ambient oxygen to singlet state oxygen. This invention also provides an acceptor bead for use in an assay, wherein the bead (a) is coated with a layer of hydrogel having directly or indirectly bound thereto a polyacrylamide-supported sugar or a polyacrylamide-supported glycan, and (b) comprises a chemiluminescer and a fluorophore, whereby when the bead is contacted with singlet state oxygen, the singlet state oxygen reacts with the chemiluminescer which in turn activates the fluorophore so as to cause the emission of light of a predetermined wavelength. This invention further provides related kits, detection methods and characterization methods.
Abstract:
A wafer treating method for making adhesive chips is provided. A liquid adhesive with two-stage property is coated on a surface of a wafer. Then, the wafer is pre-cured to make the liquid adhesive transform an adhesive film having B-stage property which has a glass transition temperature between −40 and 175 degree C., for example. After positioning the wafer, the wafer is singulated to form a plurality of chips with adhesive for chip-to-chip stacking, chip-to-substrate or chip-to-lead frame attaching.
Abstract:
A manufacturing method of a chip package structure is provided. A circuit substrate having a first surface, a second surface, and a through hole connecting the first surface and the second surface is provided. A chip having an active surface and bonding pads disposed on the active surface is provided. The chip is fixed on the circuit substrate, wherein the second surface is opposite to the active surface and the bonding pads are exposed to the through hole. Bonding wires connecting the bonding pads and the first surface are formed through the through hole. A film having an opening is formed on the first surface. The bonding wires, the bonding pads, the through hole, and part of the first surface are exposed by the opening. An encapsulant is formed to encapsulate part of the active surface, the bonding wires, and part of the first surface. The film is removed.
Abstract:
A universal chip package structure including a carrier, a chip, a plurality of bonding wires, and a molding compound is provided. The carrier has a plurality of through holes, a carrying surface, and a back surface corresponding to the carrying surface. The back surface has a plurality of contacts around the through holes. The chip with an active surface and a plurality of bonding pads on the active surface is disposed on the carrying surface. The active surface is attached to the carrying surface and the through holes expose the bonding pads. The bonding wires go through the through holes to electrically connect with the bonding pads and the contacts. In addition, the shape and size of the molding compound can be adjusted for covering the chip, the contacts, and the bonding wires.
Abstract:
A chip package structure including a first substrate, a second substrate, bumps and adhesive blocks is provided. The first substrate has first bonding pads. The second substrate is disposed above the first substrate and has second bonding pads. The bumps are respectively arranged on the first bonding pads or the second bonding pads, and the second substrate is electrically connected to the first substrate through the bumps. The adhesive material with B-stage property are respectively arranged between the first bonding pads and the second bonding pads and enclose each bump. The bumps can be stud bumps or plating bumps.
Abstract:
The present invention is an electropolishing/grinding device for an inner surface of a long tube, including at least one long tube, one electrode, at least two partitions, one fixed magnet mechanism, one driving apparatus and an axial driven mechanism. The fixed magnet mechanism and the driving apparatus form a magnetic levitation effect, which uses magnetic repulsiveness and magnetic attraction to keep the partitions away from the inner surface and avoid an eccentric situation. One of the two partitions has a plurality of springs, a plurality of protruding objects and a plurality of abrasive devices interconnected and firmly touching the inner surface of the tube for grinding.

Abstract:
A window-based flash memory storage system and a management and an access method therefor are proposed. The window-based flash memory storage system includes a window-based region and a redundant reserved region; wherein the window-based region is used to store a number of windows, each window being associated with a number of physical blocks. The redundant reserved region includes a dynamic-link area, a window-information area, a dynamic-link information area, and an boot-information area; wherein the dynamic-link area includes a plurality of dynamic allocation blocks, each being allocatable to any window. The window-information area is used to store a specific window-information set that is dedicated to a certain window within a specific range of data storage space. The dynamic-link information area is used to record the status of the allocation of the dynamic allocation blocks to the windows.
