H01L 21/461

US Classification:

Abstract:

Methods for removing silicon nitride and elemental silicon during contact preclean process involve converting these materials to materials that are more readily etched by fluoride-based etching methods, and subsequently removing the converted materials by a fluoride-based etch. Specifically, silicon nitride and elemental silicon may be treated with an oxidizing agent, e. g. , with an oxygen-containing gas in a plasma, or with Oor Oin the absence of plasma to produce a material that is more rich in Si—O bonds and is more easily etched with a fluoride-based etch. Alternatively, silicon nitride or elemental silicon may be doped with a number of doping elements, e. g. , hydrogen, to form materials which are more easily etched by fluoride based etches. The methods are particularly useful for pre-cleaning contact vias residing in a layer of silicon oxide based material because they minimize the unwanted increase of critical dimension of contact vias.

Abstract:

A metal-gas cell storage battery, such as a zinc-air cell battery, has one or more battery cells wherein each battery cell comprises a metallic anode sandwiched between a pair of gas cathodes. Each gas cathode is disposed within a rigid retaining structure. The retaining structures of each gas cathode are attached to one another by an expandable soft pocket capable of holding an electrolyte. The anode is disposed within the soft pocket. The cell is mechanically refueled by expanding the soft pocket to allow easy removal from the cell of the spent anode and easy insertion into the cell of a fresh anode.

International Classification:

H03B 19/00

US Classification:

327117, 327115

Abstract:

Embodiments of the present invention synthesize a core frequency divider by adding a switching feedback shell and using multiple clock edges to trigger the frequency divider. Feedback logic is used to determine which edge will be used. Embodiments allow multiple recursive use, which boosts the overall speed resulting frequency divider circuit 2times faster than the core frequency divider.

Abstract:

A pet animal-wearable self learning device for has been disclosed. The device determines the status of the pet animal by analyzing wireless signal information gathered by the device over a predetermined period of time. The signal information is analyzed to identify useful patterns for determining the status of a pet animal. The pet animal status typically is a multi-dimensional, qualitative or quantitative indicator such as GPS Latitude/Longitude of the pet animal, safe or unsafe condition of the pet animal The status of the pet animal is determined by various factors/conditions such as identifying whether the pet animal is in an enclosed space or not, identifying if the pet is in extreme temperature not suitable for the pet animal's health, identifying whether the pet animal is moving or stationary, identifying if the pet-wearable device has been removed.
