Abstract: The present invention provides a method for fabricating a dual gate semiconductor device. In one aspect, the method comprises forming a nitridated, high voltage gate dielectric layer over a semiconductor substrate, patterning a photoresist over the nitridated, high voltage gate dielectric layer to expose the nitridated, high voltage dielectric within a low voltage region wherein the patterning leaves an accelerant residue on the exposed nitridated, high voltage gate dielectric layer. The method further includes subjecting the exposed nitridated, high voltage dielectric to a plasma to remove the accelerant residue.

Abstract: A system is provided that includes a processor and a random access memory (RAM) coupled to the processor. The RAM is divided into public RAM and secure RAM. The system also includes a system memory coupled to the processor, wherein the system memory stores RAM resize instructions that, when executed, enable the public RAM and the secure RAM to be dynamically resized. The system memory may also store save/restore secure RAM instructions that, when executed, perform a save operation that saves the secure RAM to non-volatile memory and a restore operation that restores the secure RAM from the non-volatile memory. The system memory may also store arbitration instructions that, when executed, enable a cryptographic hardware accelerator (HWA) to be shared by a secure application and a public application.

Abstract: A method for fabricating a low resistance, low inductance device for high current semiconductor flip-chip products. A structure is produced, which comprises a semiconductor chip with metallization traces, copper lines in contact with the traces, and copper bumps located in an orderly and repetitive arrangement on each line so that the bumps of one line are positioned about midway between the corresponding bumps of the neighboring lines. A substrate is provided which has elongated copper leads with first and second surfaces, the leads oriented at right angles to the lines. The first surface of each lead is connected to the corresponding bumps of alternating lines using solder elements. Finally, the assembly is encapsulated in molding compound so that the second lead surfaces remain un-encapsulated.

Abstract: A CDMA receiver (500) minimizes the use of hardware by taking advantage of the fact that Walsh sequences of a predetermined length (e.g., 16) are comprised of inverted and non-inverted versions of smaller length (e.g., 4) sequences. The receiver (500) performs the necessary uncovering operations for example of a Walsh sequence of length 16 by performing uncovering operations using smaller length Walsh sequences such as of length 4 and then performing subsequent summing operations with inverted and non-inverted versions of the results of such uncovering operations.

Abstract: According to one embodiment, a method of increasing a perceived resolution of a display includes directing light at a optical dithering element and repeatedly transitioning the optical dithering element from a first position to a second position and then back to the first position such that the mirror alternately reflects light to a first position on the display and then to a second position on the display. Each transition of the mirror includes controlling any overshoot or ringing in the position of the optical dithering element by providing a predetermined drive signal to the optical dithering element to smoothly accelerate and decelerate the element during the traverse between the first and second positions.
