    摘要: A method for aligning a plurality of thin film transistor tiles for constructing a flat panel display. A coverplate is arranged on a coverplate support. A first layer of a bonding material is applied to at least one of a first side of each of the tiles and a surface of the coverplate on which the tiles are to be secured. The tiles are arranged on the coverplate, such that the first layer of bonding material is arranged between the tiles and the coverplate. The tiles are connected to an alignment apparatus. The tiles are aligned relative to each other and the coverplate. The tiles are at least partially secured to the coverplate.

    摘要: A method, and associated structure, for adhesively coupling a chip to an organic chip carrier. The chip is attached to a top surface of the organic chip carrier by interfacing a solder bump between a C4 solder structure on the chip and a pad on a top surface of the chip carrier. The melting temperature of the solder bump is less than the melting temperature of the C4 solder structure. A block of ferrous material is placed on a top surface of the chip. A temporary or permanent stiffener of ferrous material is placed on the top surface of the chip carrier. A permanent magnet is coupled to a bottom surface of the chip carrier. Alternatively, an electromagnetic could be utilized instead of the electromagnet. Due to the permanent magnet or the electromagnet, a magnetic force on the stiffener is directed toward the magnet and substantially flattens the first surface of the chip carrier. Similarly, a magnetic force on the block is directed toward the magnet such that the electronic component and the chip carrier are held in alignment. The solder bump is reflowed at a temperature between the melting temperature of the solder bump and the melting temperature of the C4 solder structure. The reflowing reconfigures the solder bump. The magnetic force on the block frictionally clamps the reflowed solder between the C4 solder structure and the pad. The chip and carrier are cooled, resulting in the C4 solder structure being adhesively and conductively coupled to the pad.

    摘要: Integrated circuit chips (18, 42, or 56) are packaged within openings formed in a substrate such as PCMCIA Card (20, 40, or 54), thus allowing compliance with overall width dimension requirements for standardized electronic components. The arrangement has the advantages that thermal coefficient of expansion of the chips and cards match, and that a sturdy, multilayer ceramic substrate is used for electrical connection to electronic devices such as laptops, palmtops, and the like. In addition, a second integrated circuit chip (68) can be connected directly to the embedded chip (56), thereby allowing two chips to be accommodated in a card (54) at the same location and allowing chip-to-chip electrical communication. A variety of electrical bonding methods joining the embedded chip to the card can be employed. In addition, a variety of thermal conduction arrangements can be used for cooling the embedded integrated circuit chip.

    摘要: The present invention is an apparatus and method for maximizing light beam utilization in patterning applications by positioning a plurality of mask mirrors in the light beam path to form patterned light onto a plurality of work pieces. Each mask mirror is designed so that a portion of the light beam area needed for exposing a work piece to patterned light is reflected from the mask mirror, while the remainder is passed through the mask mirror to another mask mirror. Alternatively, each mask mirror can be designed so that a portion of the light beam area needed for exposing a work piece to patterned light is passed through the mask mirror, while the remainder is reflected to another mask mirror.
