  • Publication number: 20120303151
    Abstract: The present invention provides a number of innovations in the area of computational process control (CPC). CPC offers unique diagnostic capability during chip manufacturing cycle by analyzing temporal drift of a lithography apparatus/ process, and provides a solution towards achieving performance stability of the lithography apparatus/process. Embodiments of the present invention enable optimized process windows and higher yields by keeping performance of a lithography apparatus and/or parameters of a lithography process substantially close to a pre-defined baseline condition. This is done by comparing the measured temporal drift to a baseline performance using a lithography process simulation model. Once in manufacturing, CPC optimizes a scanner for specific patterns or reticles by leveraging wafer metrology techniques and feedback loop, and monitors and controls, among other things, overlay and/or CD uniformity (CDU) performance over time to continuously maintain the system close to the baseline condition.

    Abstract: A method of placing a dental implant analog in a physical model for use in creating a dental prosthesis is provided. The physical model, which is usually based on an impression of the patient's mouth or a scan of the patient's mouth, is prepared. The model is scanned. A three-dimensional computer model of the physical model is created and is used to develop the location of the dental implant. A robot then modifies the physical model to create an opening for the implant analog. The robot then places the implant analog within the opening at the location dictated by the three-dimensional computer model.

  • Patent number: 8282866
    Abstract: Three-dimensional models are produced using a sheet material made of water-soluble paper. Each layer of the sheet material is made severable along the contour lines of the three-dimensional model by discharging water onto each layer of the sheet material. A coloring solution is discharged when each layer is deposited to color the sheet material. After the deposition is completed, the unnecessary parts of the sheet material can be pulled away to complete the three-dimensional model. Alternatively, by discharging a setting solution onto each layer of the sheet material, each layer of the sheet material in the section of the three-dimensional model can be insolubilized, and a color setting solution can be discharged to color and set the colored parts. After the deposition is completed, the deposition can be immersed in water to remove the sheet material that was not insolubilized and complete the three-dimensional model.

  • Patent number: 8161424
    Abstract: Some embodiments provide a system for accurately and efficiently modeling chemically amplified resist. During operation, the system can determine a quenched acid profile from an initial acid profile by applying multiple quenching models which are associated with different acid concentration ranges to the initial acid profile. One quenching model may be expressed as H=H0?B0, where H is an acid profile after quenching, H0 is an acid profile before quenching, and B0 is an initial base quencher profile. Another quenching model may be expressed as H=k·H0, where k is a constant. Next, the system can apply a smoothing kernel to the quenched acid profile to obtain a quenched-and-diffused acid profile. The smoothing kernel can generally be any weighted averaging function. The quenched-and-diffused acid profile can then be used to predict shapes that are expected to print on the wafer and to perform resolution enhancement techniques on a layout.

  • Patent number: 8021139
    Abstract: A three-dimensional object forming apparatus forms a three-dimensional object by binding powder particles with a curable liquid. The apparatus includes a powder layer forming unit that spreads a powder to a uniform thickness to form a powder layer. A curable liquid ejection head ejects the curable liquid to the powder layer through an ejection nozzle. A sectional data producing device produces sectional data at each of a plurality of cross sections of a desired three-dimensional object according to shape data of the desired three-dimensional object. A cross-sectional member forming section is also included by which cross-sectional members are formed by ejecting the curable liquid to the powder layer from the curable liquid ejection head according to the sectional data and thus binding the powder layer. The cross-sectional member forming section includes a permeation rate controller controlling the permeation rate of the curable liquid to the powder layer.

  • Patent number: 8010220
    Abstract: A parts delivery management system and method that synchronizes production line side parts deliveries with a production schedule to facilitate delivering the right part to the right production line location at the right time. A consolidation center for receiving parts from suppliers is co-located with an assembly plant. Parts are received in returnable containers and organized for line side delivery according to the manufacturer's production schedule. Parts are delivered to production line locations using multi-cart “trains” that transport parts to the locations. Trains made of multiple carts are assembled throughout the production day and loaded with containers holding the parts that are then delivered line side. A delivery management system application executing on a computer receives production schedule data as well as part and container data to determine which parts are needed throughout the day at the various production line side locations and when they are needed.

  • Publication number: 20110196529
    Abstract: The invention relates to a process or device for the production of a three-dimensional object by layer-wise solidification of a material which is solidifiable under the application of electromagnetic irradiation by means of mask illumination, wherein the mask is produced using an image forming unit having a prescribed resolution, which is formed from a constant number of image forming elements (pixels) being discrete and being arranged in a spatially mutually fixed manner. For the improvement of the resolution along the outer and inner contours of the sectional areas of the object to be generated layer-wise in the sub-pixel range, a multiple illumination per layer is performed, which consists of a series of multiple images that are mutually shifted in the sub-pixel range in the image/construction plane, wherein a separate mask/bitmap is produced for each shifted image.

  • Publication number: 20110183289
    Abstract: A method for making a rapid prototype of a patient's mouth to be used in the design and fabrication of a dental prosthesis. The method takes an impression of a mouth including a first installation site having a dental implant installed in the first installation site and a gingival healing abutment having at least one informational marker attached to the dental implant. A stone model is prepared based on the impression, including teeth models and model markers indicative of the at least one informational marker. The model is scanned. Scan data is generated from the scanning. The scan data is transferred to a CAD program. A three-dimensional model of the installation site is created in the CAD program. The at least one informational marker is determined to gather information for manufacturing the rapid prototype. Rapid prototype dimensional information is developed.

    Abstract: Systems for determining width/space limits for product mask layouts. A mask writer generates a first pattern on a test mask corresponding to a test mask layout. A lithography tool generates a second pattern on a wafer corresponding to a first pattern on a test mask by a lithography process using a preset exposure dose. A metrology tool measures widths of the first and second pattern. A controller determines a width/space limit for the product mask layout according to the width difference between the first and second pattern.
