  • Patent number: 7190714
    Abstract: A receiver detector of a peripheral device for use in a computer system to detect whether a receiver is electrically coupled to a data port of the peripheral device includes a modulator, a high pass filter, and a demodulator. The modulator is configured to modulate a receiver detect signal at a frequency that is higher than a noise frequency, below which high amplitude noise can develop. The high pass filter is electrically coupled to the receiver detect signal and is configured to block frequencies of the receiver detect signal that are below the noise frequency and pass a filtered receiver detect signal. The demodulator is configured to demodulate the filtered receiver detect signal and produce a recovered receiver detect signal that is indicative of whether a receiver is electrically coupled to the data port.

  • Patent number: 7190185
    Abstract: A test methodology which provides that test structures, such as transistors, are arranged in a plurality of rows. A logic circuit controls which row is to be measured. An incrementer receives a triggering signal and functions as an address adder. Each time the triggering signal rises from 0 to 1, the output of the incrementer increases by 1. The output of the incrementer serves as the address input into a decoder. The decoder is connected to the rows of test structures. Preferably, each test structure contains a control circuit which is controlled by this signal (i.e., the output of the decoder). If the test structures are transistors, bias to each of the transistors can be applied separately with a common gate, source and well, and measurement can be done with a separate drain node.

  • Patent number: 7189628
    Abstract: Dual trench depths are achieved on the same wafer by forming an initial trench having a depth corresponding to the difference in final depths of the shallow and deep trenches. A second mask is used to open areas for the deep trenches over the preliminary trenches and for the shallow trenches at additional locations. Etching of the shallow and deep trenches then proceeds simultaneously.

  • Patent number: 7189498
    Abstract: The present invention provides methods and apparatus for accomplishing a strong phase shift direct write lithography process using reconfigurable optical mirrors. A maskless lithography system is provided. The maskless direct-write lithography system provided uses an array of mirrors configured to operate in a tilting mode, a piston-displacement mode, or both in combination. The controlled mirror array is used to generate strong phase shift optical patterns which are directed onto a photoimageable layer of a substrate in order to facilitate pattern transfer. In order to avoid constraining the system to forming edges of patterns aligned with the array of mirrors, gray-scale techniques are used for subpixel feature placement.

  • Patent number: 7188330
    Abstract: A method and system is provided for handling unused structures in a slice during custom instance creation to avoid the need of a boundary scan synthesis tool, wherein the slice includes an embedded boundary scan chain having a particular length and order. Aspects of the present invention include using a software tool during slice creation to create at least one slice connectivity file. During instance creation, a customer designs a custom chip using the software tool by selecting which structures are to be use on the slice. The slice connectivity file is then reused for the instance by reading the connectivity file to determine which structures in the file are used and not used based on the customer's selections. Thereafter, the slice is reconfigured to include dummy logic in unused structures, such that the boundary scan chain retains the same length and order.

  • Patent number: 7183181
    Abstract: A method of removing an edge bead of a coated material on a substrate. The substrate is rotated, and a fluid that solvates the coated material is delivered. The delivery of the fluid is directed radially inward on the substrate at a rate of between about three millimeters per second and about twenty millimeters per second until a desired innermost fluid delivery position on the substrate is attained. Immediately upon attaining the desired innermost fluid delivery position on the substrate, the delivery of the fluid is directed radially outward off the substrate at a rate of more than zero millimeters per second and less than about four millimeters per second. The rotation of the substrate is ceased.

  • Patent number: 7185301
    Abstract: The present invention is a method and apparatus for implementing a source synchronous interface in a platform using a Generic Source Synchronous Interface (GSSI) infrastructure. The GSSI infrastructure includes the GSSI bit slices and clock management system. The GSSI bit slice includes balanced cells and bit delay elements, and may be placed either within or close to IO buffers. The GSSI clock management system includes strategically placed frame delay elements with automatic on-chip calibration and control to satisfy various clock-data phase relationships. The GSSI methodology shows how different SSIs may be constructed by combining the common GSSI architecture with unique metal layer configurations. The GSSI architecture solves a critical challenge for platform-based design such as RapidChip™ and the like. The GSSI approach introduces a completely new way to implement various SSIs based on a common minimally diffused GSSI bit slice and clock management infrastructure.
