  • Patent number: 9196357
    Abstract: Voltage balancing for a memory cell array is provided. One example method of voltage balancing for a memory array can include activating an access node coupled to a row of a memory array to provide voltage to the row of the memory array, activating a stabilizing transistor coupled to the row of the memory array to create a feedback loop, and activating a driving node coupled to a column of the memory array, wherein activating the driving node deactivates the stabilizing transistor once the column reaches a particular voltage potential.

  • Patent number: 8785904
    Abstract: A light emitting device with reduced forward voltage Vf by utilizing the excellent lateral conduction of two-dimensional electron gas (2DEG) and two-dimensional hole gas (2DHG) structure and, more specifically, by improving the vertical conduction of 2DEG and 2DHG structure by means of vertical conductive passages formed in 2DEG and 2DHG structure. The conductive passages are formed via discontinuities in 2DEG and 2DHG structure. The discontinuities can be in the form of openings by etching 2DEG or 2DHG structure, or in the form of voids by growing 2DEG or 2DHG structure on a rough surface via epitaxy facet control. The discontinuities can be formed by vertical displacement of 2DEG structure. A method is provided for manufacturing a light emitting device with reduced forward voltage same.

  • Patent number: 8392070
    Abstract: A method for determining a crash condition of a vehicle comprises the step of sensing crash acceleration in a first direction substantially parallel to a front-to-rear axis of the vehicle and providing a first acceleration signal indicative thereof. The method also comprises the step of sensing crash acceleration in a second direction substantially parallel to a side-to-side axis of the vehicle and near opposite sides of the vehicle and providing second acceleration signals indicative thereof. The method further comprises the steps of determining a transverse crash value functionally related to the second acceleration signals and comparing the determined transverse crash value against a safing threshold. The method still further comprises the step of determining a crash condition of the vehicle in response to (a) the comparison and (b) the first acceleration signal.

  • Patent number: 8273619
    Abstract: The invention includes methods of forming channel region implants for two transistor devices simultaneously, in which a mask is utilized to block a larger percentage of a channel region location of one of the devices relative to the other. The invention also pertains to methods of forming capacitor structures in which a first capacitor electrode is spaced from a semiconductor substrate by a dielectric material, a second capacitor electrode comprises a conductively-doped diffusion region within the semiconductor material, and a capacitor channel region location is beneath the dielectric material and adjacent the conductively-doped diffusion region. An implant mask is formed to cover only a first portion of the capacitor channel region location and to leave a second portion of the capacitor channel region location uncovered. While the implant mask is in place, dopant is implanted into the uncovered second portion of the capacitor channel region location.

  • Patent number: 7935602
    Abstract: The invention includes methods of forming isolation regions. An opening can be formed to extend into a semiconductor material, and an upper periphery of the opening can be protected with a liner while a lower periphery is unlined. The unlined portion can then be etched to form a widened region of the opening. Subsequently, the opening can be filled with insulative material to form an isolation region. Transistor devices can then be formed on opposing sides of the isolation region, and electrically isolated from one another with the isolation region. The invention also includes semiconductor constructions containing an electrically insulative isolation structure extending into a semiconductor material, with the structure having a bulbous bottom region and a stem region extending upwardly from the bottom region to a surface of the semiconductor material.
