摘要： One embodiment of the present invention provides an integrated circuit assembly module, including a first semiconductor die and a second semiconductor die, each semiconductor die with an active face upon which active circuitry and signal pads reside and a back face opposite the active face. The first and second semiconductor dies are positioned face-to-face within the assembly module so that signal pads on the first semiconductor die overlap with signal pads on the second semiconductor die, thereby facilitating capacitive communication between the first and second semiconductor dies. Additionally, the first and second semiconductor dies are pressed together between a first substrate and a second substrate so that a front side of the first substrate is in contact with the back face of the first semiconductor die and a front side of the second substrate is in contact with the back face of the second semiconductor die.

摘要： A electro-desorption compression system according to the present invention comprises an enclosure which includes first and second spaced-apart electrical conductors, a sorbent which is positioned in the enclosure between the first and second conductors, a sorbate which is capable of combining with the sorbent in an adsorption reaction to form a sorbate/sorbent compound, a power supply which is connected to the first and second conductors and which generates an electrical current that is conducted through the sorbate/sorbent compound to desorb the sorbate from the sorbent in a desorption reaction, and a pressure chamber which is connected to the enclosure and which receives the sorbate from the enclosure during the desorption reaction and releases the sorbate into the enclosure during the adsorption reaction. The adsorption and desorption reactions are repeated to cycle the sorbate between a relatively low pressure state during the adsorption reaction and a relatively high pressure state during the desorption reaction. Furthermore, the desorption reaction is substantially non-thermal.

摘要： An integrated circuit and associated method for reducing total signal propagation delay as well as power consumption and thermal dissipation. The integrated circuit comprises a plurality of active layers coupled together in close proximity. In order to produce the integrated circuit, at least two active layers are removed from their respective substrate after integrated circuit processing. Some of the methods that may be used include Silicon on Insulator ("SOI") and epitaxial etch stop ("EES") processes. After removal of the active layers, at least one via is implemented on a bottom surface of each active layer in order to establish a mechanical and electrical connection between the via and its associated metal interconnects. Thereafter, the active layers are coupled together by ultrasonic welding or through nitride lamination using Titanium Nitride for conductive regions and Silicon Nitride for insulative regions.

摘要： An integrated digital light modulator. In one embodiment, a light beam is split into a set of binary weighted beams which are then individually switched on or off by an optical switch. The weighted beams which are conveyed by the optical switches are then recombined to produce a modulated beam. In this manner, a fast inexpensive integrated digital light modulator may be advantageously obtained. Broadly speaking, the present invention contemplates a digital optical power modulator that comprises a binary power divider and an optical modulator. The binary power divider is configured to receive an input light beam and split it into a set of weighted beams. The optical powers of the weighted beams are related in that the ratio of the optical powers of any two weighted beams is substantially an integer power of two. The optical modulator receives the set of weighted beams from the binary power divider and receives a digital signal. The optical modulator is configured to convey weighted beams that correspond to asserted bits in the digital signal. The present invention may further include an optical combiner coupled to receive the weighted beams from the optical modulator and configured to combine the weighted beams to produce a modulated beam having a discrete optical power. A lookup table may be included to convert a desired digital power value into the digital signal provided to the optical modulator.

摘要： A process for fabricating a composite material such as that having high thermal conductivity and having specific application as a heat sink or heat spreader for high density integrated circuits. The composite material produced by this process has a thermal conductivity between that of diamond and copper, and basically consists of coated diamond particles dispersed in a high conductivity metal, such as copper. The composite material can be fabricated in small or relatively large sizes using inexpensive materials. The process basically consists, for example, of sputter coating diamond powder with several elements, including a carbide forming element and a brazeable material, compacting them into a porous body, and infiltrating the porous body with a suitable braze material, such as copper-silver alloy, thereby producing a dense diamond-copper composite material with a thermal conductivity comparable to synthetic diamond films at a fraction of the cost.

摘要： An array of termination resistors has symmetrical geometry producing essentially no net magnetic field and a resultant low inductance is fabricated on a substrate as disk resistors. Conductive through vias are formed in the substrate in an array pattern defining what will be resistor first and second contacts. Each disk resistor has one first contact located at the resistor disk center, and preferably four second contacts located symmetrically about the resistor disk and shared by four adjacent disk resistors. For each resistor, a annular-shaped disk of resistive material is fabricated on a first surface of the substrate, such that a central opening in the disk overlies at least the upper surface of a first contact via. The disk geometry and material determines its resistance. Next, a layer of conductive material is formed over the first surface of the substrate to cover at least the periphery of each disk, and to fill the central opening in each disk. This conductive material electrically couples at least the periphery of each resistive disk with each second contact via to define V.sub.T nodes, and also separately electrically couples the disk center to the underlying first contact via. Solder balls at the lower surface of each via provide an array of first and second contacts for each resistor for attaching the substrate to a printed wiring board or other substrate. An array may include hundreds of termination resistors having substantially real impedances in the range of 50 .OMEGA. to 100 .OMEGA. at frequencies up to about 12 GHz.

摘要： One embodiment of the present invention provides a system that facilitates adjusting the wavelengths of lasers via temperature control. This system includes a chip with an active face upon which active circuitry and signal pads reside. A thermal-control mechanism provides localized thermal control of two lasers mounted upon the active face of the chip. By individually controlling the temperature of the lasers, the thermal-control mechanism controls the wavelengths emitted by each respective laser. By creating a temperature gradient that causes a temperature difference between two or more lasers, the system can cause the lasers to emit different wavelengths.
