摘要： A computer implemented method for determining a timing variation for an edge of a waveform under simultaneous switching noise (SSN) conditions is provided. The method includes characterizing an impact of mutual inductive relationships on a pin while the pin is at a quiet state and characterizing a signal edge applied to the pin. The signal edge can be characterized by the slew rate in one embodiment. A voltage change related to a curve characterizing the impact of mutual inductive relationships is identified and the voltage change is applied to a curve characterizing an impact of SSN on the signal edge. The method includes calculating a timing variation correlated to the voltage change applied to the curve characterizing the impact of SSN on the signal edge and presenting the calculated timing variation.

摘要： A process for assembling a Chip-On-Lead packaged semiconductor device includes the steps of: mounting and sawing a wafer to provide individual semiconductor dies; performing a first molding operation on a lead frame; depositing epoxy on the lead frame via a screen printing process; attaching one of the singulated dies on the lead frame with the epoxy, where the die attach is done at room temperature; and curing the epoxy in an oven. Throughput improvements may be ascribed to not including a hot die attach process. An optional plasma cleaning step may be performed, which greatly improves wire bonding quality and a second molding quality. In addition, since a first molding operation is performed before the formation of epoxy to avoid the problem of the epoxy hanging in the air, the delamination risk between the epoxy and the die is avoided.

摘要： A lead frame for a semiconductor device includes at least one row of contact terminals and a die pad for receiving an integrated circuit die. An isolation material is located between the contact terminals and the die pad. The isolation material electrically isolates adjacent lead fingers from each other and from the die pad. The isolation material also holds the lead fingers in place during a wire bonding operation and thus the bottom of the lead frame does not have to be taped during the assembly process, which saves taping and detaping steps from being performed. The isolation material also prevents resin bleed problems that sometimes occur when using tape. If a sawing step is performed, the saw need only cut through the isolation material instead of a metal, and thus saw blade life is improved.

摘要： A method and apparatus for providing personalized information content over telephones is described. The creation of a voice portal is supported by the invention. Embodiments of the invention use telephone identifying information such as the calling party's number to identify, or create, user profiles for customization. The personalized content is specific to that user based on her/his telephone identifying information and may be further customized based on the current time, current date, the calling party's locales, and/or the calling party's dialect and speech patterns. Also, the telephone identifying information may support targeted advertising, content, and purchasing recommendations specific to that user. The system may use a voice password and/or touch-tone login system when appropriate to distinguish the caller or verify the caller's identity for specific activities. Typically, embodiments of the invention will immediately present a caller personalized content based on her/his profile using the appropriate dialect as well as the caller's preferred content. Profiles can be constructed as the caller uses embodiments of the invention as well as through explicit designation of preferences. For example, the user might specify an existing personalized site to use in building her/his profile. Additionally, new callers may have an initial profile generated based on one or more database lookups for demographic information based on their telephone identifying information.
