  • Patent number: 8742558
    Abstract: A method of protecting sensitive components prior to, during or subsequent to advanced die packaging processing includes applying a metal stack layer such as titanium/copper (Ti/Cu) onto the front surface of a die assembly such that the die assembly front surface is covered with the metal stack layer. A layer of titanium/copper/titanium (Ti/Cu/Ti) or a solder alloy is also applied to the back surface of the die assembly such that the back surface of the die assembly is covered with the Ti/Cu/Ti layer or solder alloy. The front surface metal stack layer and the back surface Ti/Cu/Ti layer or solder alloy prevent degradation of die metallization prior to, during or subsequent to the advanced die packaging processing.

  • Patent number: 8697503
    Abstract: A method of manufacturing a thin film electronic device includes applying a plastic coating to a rigid carrier substrate using a wet casting process, the plastic coating forming a plastic substrate and include a transparent plastic material doped with a UV absorbing additive. Thin film electronic elements are formed over the plastic substrate, and the rigid carrier substrate is released from the plastic substrate. This method forms transparent substrate materials suitable for a laser release process, through doping of the plastic material of the substrate with a UV absorber. This UV absorber absorbs in the wavelength of the lift-off laser (for example 308-351 nm, or 355 nm) with a very high absorption.

  • Patent number: 8697530
    Abstract: By modifying the dielectric liner for a spacer structure so as to exhibit an enhanced diffusion blocking characteristic, for instance by incorporating nitrogen, the out-diffusion of P-dopants, such as boron, into the dielectric material may be significantly reduced. Consequently, transistor performance, especially of P-type transistors, may be significantly enhanced while nevertheless a high degree of compatibility with conventional techniques may be maintained.

  • Patent number: 8661875
    Abstract: Methods and apparatus for detecting a leak in a gas precharged hydraulic accumulator having an initial gas charge entail activating a hydraulic pump to charge the gas precharged hydraulic accumulator and the hydraulic circuit associated with the gas precharged hydraulic accumulator when the hydraulic circuit and the hydraulic accumulator have a temperature that is substantially equivalent to an ambient temperature, e.g., on a cold start. The hydraulic pressure in the hydraulic circuit is monitored, and when a step in the hydraulic pressure is detected, various quantities are measured and used to determine a volumetric efficiency of the pump for use in later calculations of remaining gas amount.

  • Patent number: 8642420
    Abstract: A method of fabricating a semiconductor device structure begins by forming a layer of oxide material overlying a first gate structure having a first silicon nitride cap and overlying a second gate structure having a second silicon nitride cap. The first gate structure corresponds to a p-type transistor to be fabricated, and the second gate structure corresponds to an n-type transistor to be fabricated. The method continues by performing a tilted ion implantation procedure to implant ions of an impurity species in a channel region of semiconductor material underlying the first gate structure, during which an ion implantation mask protects the second gate structure. Thereafter, the ion implantation mask and the layer of oxide material are removed, and regions of epitaxial semiconductor material are formed corresponding to source and drain regions for the first gate structure. Thereafter, the first silicon nitride cap and the second silicon nitride cap are removed.

  • Patent number: 8631694
    Abstract: A connecting element connects a brake pedal to a brake force amplifier of a vehicle brake system. A helical compression spring as a first spring element and a rubbery-elastic reaction disk as a second spring element are disposed between a pedal rod and a piston rod of the connecting element, the spring elements being installed in series due to the arrangement thereof. Due to the higher spring rate of the reaction disk preferably increasing with load, the connecting element has a progressive spring characteristic line. As soon as the pedal rod contacts the reaction disk the helical compression spring and the reaction disk act in parallel and serially such that the progression of the total spring characteristic line further increases.
