  • Publication number: 20210117861
    Abstract: A sequence of models accumulates r-squared values for an increasing number of variables in order to quantify the importance of each variable to the prediction of a targeted yield or parametric response.

  • Publication number: 20210118754
    Abstract: A machine learning model for each die for imputing process control parameters at the die. The model is based on wafer sort parametric measurements at multiple test sites across the entire wafer, as well as yield results for the wafer. This allows for a better analysis of outlier spatial patterns leading to improved yield results.

  • Publication number: 20100322580
    Abstract: A fiber optic apparatus,with a panel, having a front and a back and mountable in a chassis is disclosed. The panel has a parking port in the back adapted to removably receive an adapter. The panel also has a connection port in the front adapted to removably receive the adapter. The adapter is selectively movable between the parking port and the connection port. One end of the adapter opens toward the front and another end of the adapter opens toward the back. The adapter is removably received in the parking port, and a connector attached to a fiber optic cable inserts in the end opening toward the back. The adapter then may be moved from the parking port to the connection port and removably received in the connection port. Another connector attached to another fiber optic cable may be inserted in the other end of the adapter opening toward the front.

  • Publication number: 20080063509
    Abstract: A clearance control apparatus for controlling the clearance between a rotary assembly (17) and a casing (24) surrounding the rotary assembly (17) is disclosed. The clearance control apparatus comprises a temperature measuring device (34) to measure the temperature of a radially outer portion of the rotary assembly and a cooling arrangement (28) to cool the casing (24). A control system (36) is associated with the temperature measuring device (34) and the cooling arrangement (28) to control the extent of cooling of the casing (24). The extent of cooling is dependent upon the temperature of the aforesaid portion.

  • Publication number: 20070004118
    Abstract: A method forms a semiconductor device comprising isolation structures that selectively induce strain into active regions of NMOS and PMOS devices. Form a hard mask layer over a semiconductor body. A resist layer is formed on the hard mask layer that exposes and defines isolation regions. The hard mask layer is patterned and trench regions are formed using the hard mask layer as a mask. An oxide trench liner that induces compressive strain into active regions of the PMOS region is formed within trench regions of the PMOS region. A nitride trench liner that induces tensile strain into active regions of the NMOS region is formed within the NMOS trench regions.

  • Patent number: 5607901
    Abstract: An environmentally acceptable, thermally insulating annular fluid comprised of a liquid which is non-aqueous, non-corrosive, and thermally insulating, a clay gellant, and a clay dispersant. A preferred packer fluid includes an ester originated from a vegetable or animal oil as at least a major portion of the liquid phase.
