Abstract: Various embodiments of the present disclosure are directed towards an integrated circuit (IC) chip in which a bond pad structure extends to a columnar structure with a high via density. For example, an interconnect structure is on a frontside of a substrate and comprises a first bond wire, a second bond wire, and bond vias forming the columnar structure. The bond vias extend from the first bond wire to the second bond wire. The bond pad structure is inset into a backside of the substrate, opposite the frontside, and extends to the first bond wire. A projection of the first or second bond wire onto a plane parallel to a top surface of the substrate has a first area, and a projection of the bond vias onto the plane has a second area that is 10% or more of the first area, such that via density is high.

Abstract: A terminal for implementing speech control records a correspondence between a first keyword text and a second keyword text. When a user inputs a speech, the terminal sends, to a first server for semantic parsing and logical parsing, the speech input by the user. Then, when the first server returns a parsing failure, the terminal obtains a parsed text returned by the first server, replaces the second keyword in the parsed text with the first keyword based on the correspondence, and then sends, to the first server, the text obtained after the replacement.
