Abstract: Some embodiments of the present application are directed towards an integrated circuit (IC). The integrated circuit includes a semiconductor substrate including a logic region and a memory cell region. A logic device is arranged on the logic region. A memory device is arranged on the memory cell region. An isolation structure extends into a top surface of the semiconductor substrate, and laterally separates the logic region from the memory cell region. The isolation structure includes dielectric material and has an uppermost surface and a slanted upper surface extending from the uppermost surface to an edge of the isolation structure proximate to memory cell region.

Abstract: An earphone jack includes a dielectric housing, a conductive first contact set, and a conductive second contact set. The housing has a first housing portion formed with a cylindrical first plug receiving hole, and a second housing portion connected to the first housing portion and formed with a rectangular second plug receiving hole. The first contact set includes first, second and third resilient contacts, each of which has a resilient plug contacting portion that extends into the first plug receiving hole. The second contact set includes a pair of first terminals and a pair of second terminals. The first terminals extend into the second plug receiving hole, and are disposed proximate to a lower side of the second housing portion. The second terminals extend into the second plug receiving hole, and are disposed proximate to an upper side of the second housing portion.
