  • Publication number: 20220306949
    Abstract: The present disclosure provides for processes for producing light hydrocarbons. In an embodiment, a process includes pressurizing the hydrocarbon feed in one or more pumps producing a pressurized hydrocarbon feed and heating the pressurized hydrocarbon feed in one or more heat exchangers to produce a heated hydrocarbon feed. The process includes mixing the heated hydrocarbon feed with water and separating an inter-stage hydrocarbon feed from interstage water. The process includes mixing the inter-stage hydrocarbon feed with water and separating a desalted hydrocarbon feed from outlet water. The process includes pyrolysing the desalted hydrocarbon feed in a steam cracker.

  • Patent number: 8188550
    Abstract: A method of forming an IC is presented. The method includes providing a substrate having a plurality of transistors formed thereon. The transistors have gate stack, source and drain regions. An electrical strap is formed and in contact with at least a portion of at least one sidewall of the gate stack of a first transistor to provide a continuous electrical flowpath over a gate electrode of the first transistor and the source or drain region of a second transistor.

  • Patent number: 6517235
    Abstract: A method for controlling and/or calibrating rapid thermal process systems is described. One or more wafers comprising a silicon semiconductor substrate having a refractory metal layer thereon are silicided in a RTP system at different temperatures. Sheet resistance uniformity of the wafer is measured thereby detecting silicidation phase transition temperature points at the highest uniformity points. The temperature points are used to calibrate or to reset the RTP system. A plurality of wafers comprising a silicon semiconductor substrate having a refractory metal layer thereon can be silicided in each of a plurality of rapid thermal process systems. Sheet resistance uniformity of each of the wafers is measured thereby detecting silicidation phase transition temperature points by highest sheet resistance uniformity for each of the RTP systems. The temperature points are used to match temperatures for each of the RTP systems.
