  • Patent number: 9281286
    Abstract: Microelectronic packages and methods for fabricating microelectronic packages having texturized solder pads, which can improve solder joint reliability, are provided. In one embodiment, the method includes forming a texturized dielectric region having a texture pattern, such as a hatch pattern, in an under-pad dielectric layer. A texturized solder pad is produced over the texturized dielectric region. The texturized solder pad has a solder contact surface to which the texture pattern is transferred such that the area of the solder contact surface is increased relative to a non-texturized solder pad of equivalent dimensions.

  • Patent number: 9281375
    Abstract: Methods for producing bipolar transistors are provided. In one embodiment, the method includes producing a bipolar transistor including first and second connected emitter-base (EB) junctions of varying different depths. A buried layer (BL) collector is further produced to have a third depth greater than the depths of the EB junctions. The emitters and bases corresponding to the different EB junctions are provided during a chain implant. An isolation region may overlie the second EB junction location. The BL collector is laterally spaced from the first EB junction by a variable amount to facilitate adjustment of the transistor properties. The BL collector may or may not underlie at least a portion of the second EB junction. Regions of opposite conductivity type overlie and underlie the BL collector to preserve breakdown voltage. The transistor can be readily “tuned” by mask adjustments alone to meet various device requirements.

  • Publication number: 20160062806
    Abstract: A method is provided for detecting a race condition of a parallel task when accessing a shared resource in a multi-core processing system. The method requires that a core requires only a read access to the data set of another core thereby ensuring better decoupling of the tasks. In an initialisation phase, initial values of global variables are assigned, in an activation phase, each core determines if the other core has written new values to the variables and if so, detects a race condition. Initial values are restored for each variable in a deactivation phase.

  • Publication number: 20160062331
    Abstract: The present application relates to a signal integrity module for validating one or more control signals in time domain and a method thereof. The one or more control signals are received via a signal input from at least one control signal generating unit. A new signature is generated by a signature generating unit on the basis of a current signature and the state of the one or more control signals at a watch point. The current signature is latched into a signature register upon receiving a trigger signal. The latched signature is representative of the time course of the one or more control signals at the watch point over a monitoring period defined by the trigger signal. The latched signature is compared by a signature comparator with a pre-calculated signature to validate the integrity of the one or more control signals with respect to the time domain.
