Methods and structures using laser bonding for stacking semiconductor substrates are described. In one embodiment, a method of forming a semiconductor device includes forming a trench in a first substrate, and a bond pad on a second substrate comprising active circuitry. A top surface of the bond pad includes a first material. The first substrate is aligned over the second substrate to align the trench over the bond pad. An electromagnetic beam is directed into the trench to form a bond between the first material on the bond pad and a second material at a bottom surface of the first substrate.

Abstract:
A method of forming an integrated circuit structure includes forming an opening in a substrate, with the opening extending from a top surface of the substrate into the substrate. The opening is filled with a filling material until a top surface of the filling material is substantially level with the top surface of the substrate. A device is formed over the top surface of the substrate, wherein the device includes a storage opening adjoining the filling material. A backside of the substrate is grinded until the filling material is exposed. The filling material is removed from the channel until the storage opening of the device is exposed.
Abstract:
Copper pillar tin bump on semiconductor chip comprises a copper layer composed on chip and a tin layer entirely wrapping whole outer surface of said copper layer. A method for forming of the copper pillar tin bump on semiconductor chip comprises: composing the first copper layer on said chip; applying photoresist to said first copper layer, exposing and developing a part of said photoresist, composing the copper pillar layer at the developed part of photoresist, composing the upper tin layer, removing said photoresist, removing said the first copper layer except disposing place of copper pillar layer, composing side tin layer. The minute pattern makes it possible to form a high density packaging by reducing a pitch of copper pillar tin bump. Signal delay can be reduced by low electric resistance, and underfill can be easily soaked.

Abstract:
A system, method, and computer-readable medium for a communications system to manage multiple radios and protocol stacks in a network and in a user equipment are provided. When active communications takes place over one radio system, an alternate radio system is managed in such a way that promotes both low-power operations and quick handovers. When communications are idle over all of the networks, one radio network may be assigned to be a primary radio network, and the alternate radio network may be switched off provided all incoming calls are routed to the primary radio network.

A method for controlling a precharge timing of a memory device is disclosed. The method includes making timing of generation of a signal for determining a precharge timing in a normal operation and a signal for determining a precharge timing in a refresh operation different from each other by making timing of generation of a signal for controlling the normal operation and a signal for controlling the refresh operation different from each other.
Abstract:
A Lobster Eye X-ray Imaging System based on a unique Lobster Eye (LE) structure, X-ray generator, scintillator-based detector and cooled CCD (or Intensified CCD) for real-time, safe, staring Compton backscatter X-ray detection of objects hidden under ground, in containers, behind walls, bulkheads etc. In contrast to existing scanning pencil beam systems, Lobster Eye X-Ray Imaging System's true focusing X-ray optics simultaneously acquire ballistic Compton backscattering photons (CBPs) from an entire scene irradiated by a wide-open cone beam from one or more X-ray generators. The Lobster Eye X-ray Imaging System collects (focuses) thousands of times more backscattered hard X-rays in the range from 40 to 120 keV (or wavelength λ=0.31 to 0.1 Å) than current backscatter imaging sensors (BISs), giving high sensitivity and signal-to-noise ratio (SNR) and penetration through ground, metal walls etc. The collection efficiency of Lobster Eye X-ray Imaging System is optimized to reduce emitted X-ray power and miniaturize the device. This device is especially advantageous for and satisfies requirements of X-ray-based inspection systems, namely, penetration of the X-rays through ground, metal and other material concealments; safety; and man-portability. The advanced technology disclosed herein is also applicable to medical diagnostics and military applications such as mine detection, security screening and a like.
