Abstract:

The present invention is directed to a number of improvements in methods for hot-carrier device degradation modeling and extraction. Several improvements are presented for the improvement of building device degradation models, including allowing the user to select a device parameter used to build the device degradation model independent of the device parameter selected. The user can also select the functional relation between stress time and degradation level. To further improve accuracy, multiple acceleration parameters can be used to account for different regions of the degradation process. Analytical functions may be used to represent aged device model parameters, either directly or by fitting measured device parameters versus device age values, allowing devices with different age values to share the same device model. The concept of binning is extended to include device degradation. In addition to a binning based on device width and length, age is added.

International Classification:

B23K 31/02

US Classification:

22818022, 228215

Abstract:

Embodiments of invention are directed to the formation of microprobes (i. e. compliant electrical or electronic contact elements) on a temporary substrate, dicing individual probe arrays, and then transferring the arrays to space transformers or other permanent substrates. Some embodiments of the invention transfer probes to permanent substrates prior to separating the probes from a temporary substrate on which the probes were formed while other embodiments do the opposite. Some embodiments, remove sacrificial material prior to transfer while other embodiments remove sacrificial material after transfer. Some embodiments are directed to the bonding of first and second electric components together using one or more solder bumps with enhanced aspect ratios (i. e. height to width ratios) obtained as a result of surrounding the bumps at least in part with rings of a retention material. The retention material may act be a solder mask material.

Abstract:

Methods, program products, and systems implementing integrated repository of structured and unstructured data are disclosed. An integrated environment is provided for accessing, structured data (e. g. , data of a relational database) and unstructured data (e. g. , data stored in a text or binary file), including creating, managing, modifying, and searching the structured data and unstructured data. The integrated environment can include an integrated user interface, a set of commands and application programming interface (API), and storage for a relational database and a document repository. The integrated environment can include a database abstraction layer that allows database operations on both the structured data and the unstructured data.

International Classification:

H03L 7/107

US Classification:

331 17, 331185, 327156, 455 76

Abstract:

Techniques for generating oscillator signals in a wireless communication device are described. A phase-locked loop (PLL) may be used to generate an oscillator signal for a selected frequency channel. Different PLL settings may be used for the blocks in the PLL for different frequency channels. The different PLL settings may be for different PLL loop bandwidths, different amounts of charge pump current, different frequency equations associated with different sets of high and low divider ratios, different frequency division schemes associated with different prescaler ratios and/or different integer divider ratios, high side or low side injection for a super-heterodyne receiver or transmitter, and/or different supply voltages for one or more circuit blocks such as an oscillator. A suitable set of PLL settings may be selected for each frequency channel such that adverse impact due to spurs can be mitigated.
