  • Publication number: 20130107259
    Abstract: An overlay target for use in imaging based metrology is disclosed. The overlay target includes a plurality of target structures including three or more target structures, each target structure including a set of two or more pattern elements, wherein the target structures are configured to provide metrology information pertaining to different pitches, different coverage ratios, and linearity. Pattern elements may be separated from adjacent pattern elements by non-uniform distance; pattern elements may have non-uniform width; or pattern elements may be designed to demonstrate a specific offset as compared to pattern elements in a different layer.

  • Patent number: 8426348
    Abstract: Antimicrobial lubricant compositions are disclosed. The antimicrobial lubricant compositions are particularly useful in providing antimicrobial capability to a wide-range of medical devices. The compositions include an oil lubricant. Representative lubricants may include polydimethyl siloxane, trifluoropropyl copolymer polysiloxane, and a copolymer of dimethylsiloxane and trifluoropropylmethylsiloxane. The compositions include rheology modifiers as necessary. The compositions also include antimicrobial agents, which may be selected from a wide array of agents. Representative antimicrobial agents include of aldehydes, anilides, biguanides, bis-phenols, quaternary ammonium compounds, cetyl pyridium chloride, cetrimide, alexidine, chlorhexidine diacetate, benzalkonium chloride, and o-phthalaldehyde.

  • Publication number: 20130060354
    Abstract: The invention may be embodied in a system and method for monitoring and controlling feedback control in a manufacturing process, such as an integrated circuit fabrication process. The process control parameters may include translation, rotation, magnification, dose and focus applied by a photolithographic scanner or stepper operating on silicon wafers. Overlay errors are used to compute measured parameters used in the feedback control process. Statistical parameters are computed, normalized and graphed on a common set of axes for at-a-glance comparison of measured parameters and process control parameters to facilitate the detection of problematic parameters. Parameter trends and context relaxation scenarios are also compared graphically. Feedback control parameters, such as EWMA lambdas, may be determined and used as feedback parameters for refining the APC model that computes adjustments to the process control parameters based on the measured parameters.

  • Publication number: 20060242313
    Abstract: Packets received over a network are routed using a packet engine of the invention based on information contained in layer 4 or above. The information for switching is contained in the header information of the packet. Based on this higher level information, the packet engine may drop the packet, redirect the packet, load balance the packet, perform bandwidth provisioning (e.g., limit the speed of a connection), or adjust quality of service (e.g., change priority or rearrange a queue of packets to be handled), or combinations of these.

  • Patent number: 6978535
    Abstract: A pressing device for thin-film circuits and terminals includes the characteristics of a machine base provided with a bottom panel, and a cutting block and a pressing block capable of intermittent up-and-down displacement at an interior thereof; an inner modular base capable of elastic displacement and flexibly disposed in a projecting column on the bottom panel; and an outer modular base fixed at an outer side of the inner modular base. Wherein, the outer modular base presses onto an upper pressing plane using downward displacement of the pressing block, and a cutting-edge portion slides upward along a rear sliding wall of the inner modular base, thereby accurately puncturing, stamping and connecting a plurality of terminals onto silvered wires of a thin-film circuit at a time.
