Title: Efficient system management synchronization and memory allocation
Inventor: COOPER BARNES
IPC: G06F1/32
Filed: 2004-10-06
Abstract: A method and apparatus for optimization of multiprocessor synchronization and allocation of system management memory space is herein described. When a system management interrupt (SMI) is received, a first processor checks the state of a second processor, which may be done by checking a storage medium storing values representative of the second processor's state. The first processor handles the SMI or waits for the second processor dependent on the state of the second processor. Furthermore, system management memory is allocated where a first system management memory space assigned to a first processor overlaps a second system management memory space assigned to a second processor, leaving first and second non-overlapping region.

Title: Ceramic substrate with chip type electronic component mounted thereon and process for manufacturing the same
Inventor: TSUKIZAWA TAKAYUKI
IPC: H05K1/18
Filed: 2005-05-25
Abstract: Since solder is used for mounting an electronic component on a ceramic substrate in the conventional process for manufacturing an electronic component, height of the ceramic substrate including the electronic component increases by the coating amount of solder, which is not preferable for reducing the height of the electronic component. Profile can be reduced by burying the electronic component in the ceramic substrate, but a cavity must be provided in the ceramic substrate. In the inventive chip mounting substrate (10), a chip type electronic component (12) comprising a sintered ceramics as a substrate and having external terminal electrodes (12D, 12E) is mounted on a ceramic substrate (11) having a surface electrode (11C). The surface electrode (11C) of the ceramic substrate (11) and the external terminal electrodes (12D, 12E) of the chip type electronic component (12) are integrated by sintering.

Title: Apparatus and method for drying substrate
Inventor: HANSEN ERIC
IPC: H01L21/00
Filed: 2005-02-25
Abstract: The present application describes a system for drying substrates which includes a chamber and an inner vessel having an upper edge positioned within the chamber. Process fluid is directed into the inner vessel and allowed to cascade over the upper edge. The upper edge of the inner vessel is lowered to thereby lower the cascade level across the surface of the substrate, while a drying vapor is introduced into the chamber. As the cascade level descends across the surface of the substrate, the substrate surface is exposed to the drying vapor. Megasonic energy may be directed into the inner vessel to accelerate drying using boundary layer thinning.
