  • Publication number: 20240371803
    Abstract: A method is provided for forming a redistribution layer (RDL) structure. An RDL feature is formed over a die, and the RDL feature is electrically connected to a contact of the die. A passivation layer is formed over the RDL feature. A patterned etch mask layer is formed over the passivation layer, and has an opening over a portion of the RDL feature. The passivation layer is patterned using the patterned etch mask layer disposed thereon. The patterned etch mask layer is removed after the passivation layer is patterned using the patterned etch mask layer disposed thereon. The passivation layer is etched to form a passivation opening in the passivation layer, and the portion of the RDL feature is exposed through the passivation opening.

  • Publication number: 20240363467
    Abstract: In order to reduce the incidence of stress concentration areas in an etched opening, a thinner polyimide layer is deposited to minimize gap formation therein, and a descum process is then performed to increase the angle of the presented layer surface. Reduction of the stress in this manner reduces the incidence of cracking of the later formed metal contact, which improves the overall pass rates of semiconductor devices so manufactured.

  • Patent number: 12114503
    Abstract: Some embodiments relate to an integrated chip that includes a first source/drain region and a second source/drain region disposed in a substrate. A plane that is substantially perpendicular to an upper surface of the substrate traverses the first source/drain region and the second source/drain region. Agate electrode extends over a channel region in the substrate between the first source/drain region and the second source/drain region. The gate electrode is separated from the channel region by way of a charge trapping dielectric structure. The charge trapping dielectric structure includes a tunnel dielectric layer, a charge trapping dielectric layer over the tunnel dielectric layer, and a blocking dielectric layer over the charge trapping dielectric layer. The channel region has a channel width measured perpendicularly to the plane, and the tunnel dielectric layer has different thicknesses at different respective points along the channel width.
