| 20110022994 | Determining Source Patterns for Use in Photolithography - Embodiments of a computer system, a process, a computer-program product (i.e., software), and a data structure or a file for use with the computer system are described. These embodiments may be used to determine or generate source patterns that define illumination patterns on photo-masks during a photolithographic process. Moreover, a given source pattern may be determined concurrently with an associated mask pattern (to which a given photo-mask corresponds) or sequentially (i.e., either the given source pattern may be determined before the associated mask pattern or vice versa.). During the determining, the given source pattern may be represented using one or more level-set functions. Additionally, the source pattern may be determined using an Inverse Lithography (ILT) calculation. | 01-27-2011 |

| 20090276198 | Modeling Conductive Patterns Using An Effective Model - A model of a sample with a periodic or non-periodic pattern of conductive and transparent materials is produced based on the effect that the pattern has on TE polarized incident light. The model of the pattern may include a uniform film of the transparent material and an underlying uniform film of the conductive material. When the pattern has periodicity in two directions, the model may include a uniform film of the transparent material and an underlying portion that based on the physical characteristics of the periodic pattern in the TM polarization direction. When the sample includes an underlying periodic pattern that is orthogonal to the top periodic pattern, the sample may be modeled by modeling the physical characteristics of the top periodic pattern and the effect of the bottom periodic pattern. The model may be stored and used to determine a characteristic of the sample. | 11-05-2009 |
| 20090296075 | Imaging Diffraction Based Overlay - An overlay error is determined using a diffraction based overlay target by generating a number of narrow band illumination beams that illuminate the overlay target. Each beam has a different range of wavelengths. Images of the overlay target are produced for each different range of wavelengths. An intensity value is then determined for each range of wavelengths. In an embodiment in which the overlay target includes a plurality of measurement pads, which may be illuminated and imaged simultaneously, an intensity value for each measurement pad in each image is determined. The intensity value may be determined statistically, such as by summing, finding the mean or median of the intensity values of pixels in the image. Spectra is then constructed using the determined intensity value, e.g., for each measurement pad. Using the constructed spectra, the overlay error may then be determined. | 12-03-2009 |

| 20100236823 | RING OF POWER VIA - Systems and methods for providing plated through-holes (PTH) in PCBs, which advantageously allow improved soldering capabilities, are described herein. Such systems and methods are achieved by reducing the heat sinking effects of PTHs by providing one or more vias surrounding the PTHs to provide an electrical connection between the PTH and the internal and bottom conductive layers of a PCB. In this regard, the PTHs are spaced apart from at least one of the internal conductive layers (e.g., ground or power layers), so the heat sinking effects are reduced. This feature enables molten solder to substantially fill the entire PTH before freezing, thereby improving the mechanical and electrical connection between an electrical component and the PCB. | 09-23-2010 |

| 20110061233 | RIB REINFORCEMENT OF PLATED THRU-HOLES - Systems and methods for providing mechanically reinforced plated through-holes (PTH) in PCBs, which advantageously allow improved soldering capabilities and reliability, are described herein. Such systems and methods are achieved by reducing the heat sinking effects of PTHs by providing one or more vias surrounding the PTHs to provide an electrical connection between the PTH and the internal and bottom conductive layers of a PCB. In this regard, the PTHs are spaced apart from at least one of the internal conductive layers (e.g., ground or power layers), so the heat sinking effects are reduced. This feature enables molten solder to substantially fill the entire PTH before freezing, thereby improving the mechanical and electrical connection between an electrical component and the PCB. One or more electrically-nonfunctional lands (or “rib reinforcements”) are provided in internal conductive layers to mechanically support the walls of the PCB. These rib reinforcements improve the mechanical strength of the PTHs without affecting the electrical performance and without impacting the ability to solder components to the PCB. | 03-17-2011 |
