  • Publication number: 20240096548
    Abstract: An electronic device is disclosed. The electronic device can include a core having a top core section and a bottom core section, a laminate substrate, where the laminate substrate having a void through which the top and bottom core sections are connected, and the laminate substrate having conductive traces. The electronic device can further include a base having a first side including a recess and a second side opposite the first site, at least one of the core and the laminate substrate disposed in the recess of the base, where the base has one or more terminals on the second side to electrically connect to an external device.

  • Publication number: 20230377890
    Abstract: A method for etching a hardmask layer includes forming a photoresist layer comprising an organometallic material on a hardmask layer comprising a metal-containing material, exposing the photoresist layer to ultraviolet radiation through a mask having a selected pattern, removing un-irradiated areas of the photoresist layer to pattern the photoresist layer, forming a passivation layer comprising a carbon-containing material selectively on a top surface of the patterned photoresist layer, and etching the hardmask layer exposed by the patterned photoresist layer having the passivation layer formed thereon.

  • Publication number: 20220005688
    Abstract: Embodiments disclosed within include a method for etching a hardmask layer includes forming a photoresist layer comprising an organometallic material on a hardmask layer comprising a metal-containing material, exposing the photoresist layer to ultraviolet radiation through a mask having a selected pattern, removing un-irradiated areas of the photoresist layer to pattern the photoresist layer, forming a passivation layer comprising a carbon-containing material selectively on a top surface of the patterned photoresist layer, including selectively depositing passivation material over a top surface of a patterned photoresist layer trimming undesired portions of the passivation material, and etching the hardmask layer exposed by the patterned photoresist layer having the passivation layer formed thereon.

  • Patent number: 10867795
    Abstract: A method of etching a hardmask layer formed on a substrate is provided. The method includes supplying an etching gas mixture to a processing region of a processing chamber. A device is disposed in the processing region when the etching gas mixture is supplied to the processing region. The device comprises a substrate and a hardmask layer formed over the substrate. The etching gas mixture comprises a fluorine-containing gas, a silicon-containing gas, and an oxygen-containing gas. The method further includes providing RF power to the etching gas mixture to form a plasma in the processing region. The plasma is configured to etch exposed portions of the hardmask layer.
