Abstract: An electronic package includes a semiconductor die, conductive pillars extending outwardly from the semiconductor die, and a liquid crystal polymer (LCP) body surrounding the semiconductor die and having openings therein receiving respective ones of the conductive pillars. A first interconnect layer is on the LCP body and contacts the openings. Conductive bodies are in the openings to connect the conductive pillars to the first interconnect layer.

Abstract: Aspects of the present disclosure include fabricating integrated circuit (IC) structures using a boron etch-stop layer, and IC structures with a boron-rich region therein. Methods of forming an IC structure according to the present disclosure can include: growing a conductive epitaxial layer on an upper surface of a semiconductor element; forming a boron etch-stop layer directly on an upper surface of the conductive epitaxial layer; forming an insulator on the boron etch-stop layer; forming an opening within the insulator to expose an upper surface of the boron etch-stop layer; annealing the boron etch-stop layer to drive boron into the conductive epitaxial layer, such that the boron etch-stop layer becomes a boron-rich region; and forming a contact to the boron-rich region within the opening, such that the contact is electrically connected to the semiconductor element through at least the conductive epitaxial layer.
Abstract: A method for fabricating semiconductor device is disclosed. The method includes the steps of: providing a substrate; forming an interfacial layer on the substrate; forming a high-k dielectric layer on the interfacial layer; forming a first bottom barrier metal (BBM) layer on the high-k dielectric layer; performing a thermal treatment; removing the first BBM layer; and forming a second BBM layer on the high-k dielectric layer.
Abstract: Self-aligned sextuple patterning (SASP) processes and mask design methods for the semiconductor manufacturing are invented. The inventions pertain to methods of forming one and/or two dimensional features on a substrate having the feature density increased to six times of what is possible using the standard optical lithographic technique; and methods to release the overlay requirement when patterning the critical layers of semiconductor devices. Our inventions provide production-worthy methods for the semiconductor industry to continue device scaling beyond 15 nm (half pitch).
