  • Publication number: 20230151489
    Abstract: A deposition apparatus and a method are provided. A method includes placing a substrate over a platform in a chamber of a deposition system. A precursor material is introduced into the chamber. A first gas curtain is generated in front of a first electromagnetic (EM) radiation source coupled to the chamber. A plasma is generated from the precursor material in the chamber, wherein the plasma comprises dissociated components of the precursor material. The plasma is subjected to a first EM radiation from the first EM radiation source. The first EM radiation further dissociates the precursor material. A layer is deposited over the substrate. The layer includes a reaction product of the dissociated components of the precursor material.

  • Publication number: 20230119519
    Abstract: A microwave coupling moisture content sensor and a method for deriving a linear regression correlation between signal data generated by a microwave moisture content sensor and moisture contents of objects are disclosed. The microwave coupling moisture content sensor includes a microwave resonator and a signal feeding member or a microwave emitting member. An object is placed outside the microwave resonator, and the signal feeding member or the microwave emitting member emits microwaves, which penetrate the object. The resonance frequency and the amplitude of the microwave resonator are measured to obtain the moisture content of the object. Several objects having known moisture contents are detected by the microwave coupling moisture content sensor to obtain corresponding resonance frequency and amplitude.

  • Publication number: 20220375782
    Abstract: A method includes forming a mask layer above a substrate. The substrate is patterned by using the mask layer as a mask to form a trench in the substrate. An isolation structure is formed in the trench, including feeding first precursors to the substrate. A bias is applied to the substrate after feeding the first precursors. With the bias turned on, second precursors are fed to the substrate. Feeding the first precursors, applying the bias, and feeding the second precursors are repeated.

  • Patent number: 11508572
    Abstract: A method includes forming a dummy gate structure over a wafer. Gate spacers are formed on either side of the dummy gate structure. The dummy gate structure is removed to form a gate trench between the gate spacers. A gate dielectric layer is formed in the gate trench. A gate electrode is formed over the gate dielectric layer. Forming the gate dielectric layer includes applying a first bias to the wafer. With the first bias turned on, first precursors are fed to the wafer. The first bias is turned off. After turning off the first bias, second precursors are fed to the wafer.

  • Publication number: 20220352018
    Abstract: A layer of carbon (e.g., graphite or graphene) at a metal interface (e.g., between an MEOL interconnect and a gate contact or a source or drain region contact, between an MEOL contact plug and a BEOL metallization layer, and/or between BEOL conductive structures) is used to reduce contact resistance at the metal interface, which increases electrical performance of an electronic device. Additionally, in some implementations, the layer of carbon may help prevent heat transfer from a second metal to a first metal when the second metal is deposited over the first metal. This results in more symmetric deposition of the second metal, which reduces surface roughness and contact resistance at the metal interface. As an alternative, in some implementations, the layer of carbon is etched before deposition of the second metal in order to reduce contact resistance at the metal interface.
