  • Patent number: 7516427
    Abstract: A methodology for characterization of an IP (Intellectual Property) component is provided. Digital pins are recognized by skipping analog pins and special IO pins. First two layers of the IP component are classified in response to connection of the input pins. Partial circuits of the IP component are extracted for simulation. Three corners of IP library are generated. Therefore, input capacitance of the IP component is simulated.

  • Patent number: 7389488
    Abstract: A method of finding a driving strength and a record medium accessible by a computer to store a program thereof are provided. The method is adapted to find the driving strength of an output pin of a target cell. Wherein, the driving strength of the output pin of the target cell is provided from the driving strength of a corresponding last level device. In this method, at least one candidate standard cell is searched in a standard cell library according to the last level device. Then, the driving strength of the target cell is interpolated between the driving strengths of the candidate standard cells to obtain the driving strength of the output pin of the target cell.

  • Patent number: 5952244
    Abstract: A method, in a plasma processing chamber, for etching through a selected portion of layers of a wafer stack, which comprises an anti-reflective layer and a metallization layer disposed below the anti-reflective layer. The method comprises the step of etching at least partially through the anti-reflective layer of the wafer stack with a first chemistry that comprises both an etchant chemical and a polymer-forming chemical. Further, the method comprises the step of etching at least partially through the metallization layer of the wafer stack with a second chemistry different from the first chemistry.

  • Patent number: 4210678
    Abstract: Herbs or spices are sterilized for commercial sale purposes by extruding the products through a small orifice in a die, preferably while maintaining the products at a temperature above approximately 220.degree. F. Before extrusion the herbs or spices are moistened, and then are tempered or allowed to remain in the presence of the moisture until the moisture level thereof has equilbrated to a range of about 16-20% by weight. When the moistened and tempered products are extruded, they expand slightly upon emerging from the die orifice, and are severed into pieces by a rotating knife. The severed pieces may then be ground into any desired particle size.
