  • Patent number: 6221736
    Abstract: A method for fabricating a shallow trench isolation structure is described, in which a pad oxide layer, a silicon oxy-nitride layer and the silicon nitride layer are sequentially formed on the substrate. Photolithography and etching are further conducted to form a trench in the substrate. A liner oxide layer is then formed on the exposed substrate surface in the trench, followed by removing portions of the silicon nitride layer and the silicon oxy-nitride layer by wet etching. After this, the trench is filled with an oxide material d the excessive oxide material is removed by using the silicon nitride layer as barrier layer. The remaining silicon nitride layer and the silicon oxy-nitride layer are further removed to complete the fabrication of a shallow trench isolation structure.

  • Patent number: 6222895
    Abstract: A PLL circuit that includes a sampled phase detector, a filter and a voltage-controlled oscillator (VCO) is disclosed. The sampled phase detector compares an incoming reference signal, Vref, and the output of the VCO, VO, to generate an error signal, Ierr, representing the phase difference between the reference signal, Vref, and the VCO output, VO. The error signal, Ierr, is filtered by a low pass filter and applied to the VCO to produce an output signal, VO, that tracks the phase of the reference signal, Vref. Jitter is reduced by reducing the delay between the sampled phase detector and the VCO. Delay is reduced by utilizing short current pulses, as opposed to the continuous charge-pump current produced by conventional sampled phase detectors. The sampled phase detector injects all the charge-pump current into the VCO at once, reducing the delay by up to half of a clock cycle.

  • Patent number: 6221776
    Abstract: The present invention advantageously provides a method and apparatus in which a sacrificial anti-reflective coating is used as an etch stop layer to protect a material from being etched. The anti-reflective coating has a relatively high viscosity which allows it to pool in recess regions as it is spin-on deposited across a surface having elevational disparities. This feature of the anti-reflective coating may be taken advantage of when using the anti-reflective coating as an etch stop layer. That is, the anti-reflective coating may be spin-on deposited across a substrate and structures arranged upon the substrate to allow the anti-reflective coating to accumulate in the recess regions interposed between the structures. In this manner, a thicker layer of the anti-reflective coating is formed in the recessed region above the substrate than above the structures which comprises a first layer of material arranged upon a second layer of material.

  • Patent number: 6219911
    Abstract: In a flip chip bonding method, polymer bumps are formed, using a bonding tool, on an IC chip, held via suction to the bonding tool. An insulating adhesive film is pressed onto the upper surface of a circuit board held via suction with a suction stage. Heat is then applied to bring the film into close contact with bond pads of the circuit board. At this point, the bonding tool is moved downward, bonding the polymer bumps to the circuit board electrodes. During the time of this downward movement, bonding of the polymer bumps to the circuit board bond pads can be achieved by piercing the insulating adhesive film with the polymer bumps, and it is found that strong bonding can be achieved with adequate reliability. This method eliminates the need for a process in which through-holes must be pierced in the insulating adhesive film to accommodate the polymer bumps.

  • Patent number: 6223324
    Abstract: The invention provides methods and apparatus for processing information, e.g., audio, video or image information, for transmission in a communication system. In an illustrative embodiment, the value of a single-bit or multiple-bit criticality flag is determined for each of the programs in a set of multiple programs to be transmitted in the system. The information bits for each of the programs are then separated into n classes, where n is greater than or equal to two, based on the values of the criticality flags for the programs. Each of the classes is provided with a different level of error protection, e.g., through the use of different convolutional codes or other suitable techniques. The program or programs having the highest criticality flag values in a given frame or other designated time interval thus have a larger percentage of their information bits assigned to the class that is provided with the highest level of error protection.

  • Patent number: 6223271
    Abstract: An apparatus and method are provided for detecting physical memory connected to a memory slot of a computer. The amount of physical memory within each bank is determined during boot up of the computer. Specifically, an extended physical address range exceeding 232 bytes can be accessed and, therefore, detected from boot up code contained within a ROM. The ROM contains translation tables which allow a 32 bit linear address to be translated to a physical address which can reside at boundary address locations of the fill extended physical address range. Each boundary location can be tested by writing to and reading from the specific boundary addresses to determine if physical memory is present within a sector in which the boundary address page resides. The sectors are equally spaced across the physical address range so that boot up can detect physical memory sequentially along the sector boundaries, either beginning with the lowest addressable sector or beginning at the highest addressable sector.
