Abstract:
An information handling system circuit board has an opening formed through it proximate a coupling point of an integrated circuit to the circuit board. The opening manages stress at the coupling point of the integrated circuit to the circuit board to reduce the risk of damage to the coupling point during deformation of the circuit board, such as when the circuit board is coupled to a chassis or when a component is pressed into the circuit board. In one embodiment, rectangular openings are formed at diagonally opposed corners of a BSA integrated circuit. In alternative embodiments, openings of varying shape, such as slots or curved slots, are formed at selected corners of the integrated circuit.

A hand-held device includes a first body, a second body, a sliding module, and a guiding module. The sliding module is disposed between the first body and the second body, so that the second body is able to be slid on a two-dimensional plane relative to the first body. The guiding module includes a first guiding part and a second guiding part. The first guiding part is fixed to the first body. The second guiding part is fixed to the second body and coupled to the first guiding part. Besides, the second guiding part is able to be moved along a guiding path relative to the first guiding part, so that the second body is able to be slid along the guiding path on the two-dimensional plane relative to the first body.

A CMOS image sensor having increased capacitance that allows a photo-diode to generate a larger current is provided. The increased capacitance reduces noise and the dark signal. The image sensor utilizes a transistor having nitride spacers formed on a buffer oxide layer. Additional capacitance may be provided by various capacitor structures, such as a stacked capacitor, a planar capacitor, a trench capacitor, a MOS capacitor, a MIM/PIP capacitor, or the like. Embodiments of the present invention may be utilized in a 4-transistor pixel or a 3-transistor pixel configuration.

Abstract:
An improved thin film inductor design is described. A spiral geometry is used to which has been added a core of high permeability material located at the center of the spiral. If the high permeability material is a conductor, care must be taken to avoid any contact between the core and the spiral. If a dielectric ferromagnetic material is used, this constraint is removed from the design. Several other embodiments are shown in which, in addition to the high permeability core, provide low reluctance paths for the structure. In one case this takes the form of a frame of ferromagnetic material surrounding the spiral while in a second case it has the form of a hollow square located directly above the spiral.
Abstract:
This invention provides a method for forming a self aligned contact without key holes using a two step sidewall spacer deposition. The process begins by providing a semiconductor structure having a device layer, a first inter poly oxide layer (IPO-1), and a conductive structure (such as a bit line) thereover, and having a contact area on the device layer adjacent to the conductive structure. The semiconductor structure can further include an optional etch stop layer overlying the first inter poly oxide layer. The conductive structure comprises at least one conductive layer with a hard mask thereover. A first spacer layer is formed over the hard mask and the IPO-1 layer and anisotropically etched to form first sidewall spacers on the sidewalls of the conductive structure up to a level above the bottom of the hard mask and below the level of the top of the hard mask such that the profile of the first sidewall spacers are not concave at any point. A second spacer layer is formed over the first sidewall spacers and anisotropically etched to form second sidewall spacers, having a profile that is not concave at any point. A second inter poly oxide layer is formed over the second sidewall spacers, the hard mask, and the IPO-1 layer, whereby the second inter poly oxide layer is free from key holes. A contact opening is formed in the second inter poly oxide layer and the first inter poly oxide layer over the contact area. A contact plug is formed in the contact openings.
