  • Patent number: 9985010
    Abstract: An integrated package may be manufactured in a die face up orientation with a component proximate to the attached die by creating a cavity in the mold compound during fabrication. The cavity is created with an adhesive layer on the bottom to hold a component such that the top surface of the component is co-planar with the top surface of the attached die. This may allow backside grinding to take place that will not damage the component because the top surface alignment between the attached die and the component prevents the depth of the cavity from extending into the portion of the package that is ground away.

  • Patent number: 9972499
    Abstract: A method of manufacturing a semiconductor device includes providing a semiconductor substrate having a front surface and a back surface; forming a transition metal layer on a surface of the semiconductor substrate; and exposing the semiconductor substrate having the transition metal layer formed thereon to a hydrogen plasma atmosphere formed by microwaves, to cause the transition metal layer to generate heat. During exposure of the semiconductor substrate, a portion of the semiconductor substrate contacting the transition metal layer is heated by a transfer of heat from the transition metal layer and, at an interface of the transition metal layer and the semiconductor substrate, an ohmic contact is formed by reaction of the transition metal layer and the semiconductor substrate, such as to form a transition metal silicide when the semiconductor substrate is silicon carbide. The ohmic contact provides a lower contact resistivity and device properties can be prevented from degrading.

  • Patent number: 9941162
    Abstract: Disclosed are methods and integrated circuit (IC) structures. The methods enable formation of a gate contact on a gate above (or close thereto) an active region of a field effect transistor (FET) and provide protection against shorts between the gate contact and metal plugs on source/drain regions and between the gate and source/drain contacts to the metal plugs. A gate with a dielectric cap and dielectric sidewall spacer is formed on a FET channel region. Metal plugs with additional dielectric caps are formed on the FET source/drain regions such that the dielectric sidewall spacer is between the gate and the metal plugs and between the dielectric cap and the additional dielectric caps. The dielectric cap, dielectric sidewall spacer and additional dielectric caps are different materials preselected to be selectively etchable, allowing for misalignment of a contact opening to the gate without risking exposure of any metal plugs and vice versa.
