摘要： IC devices with angled interconnects are disclosed herein. An interconnect, specifically a trench or line interconnect, is referred to as an “angled interconnect” if the interconnect is neither perpendicular nor parallel to any edges of front or back faces of the support structure, or if the interconnect is not parallel or perpendicular to interconnect in another region of an interconnect layer. Angled interconnects may be used to decrease the area of pitch transition regions. Angled interconnects may also be used to decrease the area of pitch offset regions.

摘要： Embodiments herein describe techniques for a semiconductor device including a substrate. A first capacitor includes a first top plate and a first bottom plate above the substrate. The first top plate is coupled to a first metal electrode within an inter-level dielectric (ILD) layer to access the first capacitor. A second capacitor includes a second top plate and a second bottom plate, where the second top plate is coupled to a second metal electrode within the ILD layer to access the second capacitor. The second metal electrode is disjoint from the first metal electrode. The first capacitor is accessed through the first metal electrode without accessing the second capacitor through the second metal electrode. Other embodiments may be described and/or claimed.

摘要： An integrated circuit (IC) includes a first memory cell and a second memory cell. The first memory cell includes (i) a first transistor and (ii) a first capacitor coupled to the first transistor, where an upper electrode of the first capacitor is coupled to a first conductive structure. The second memory cell is above the first memory cell. The second memory cell includes (i) a second transistor and (ii) a second capacitor coupled to the second transistor. An upper electrode of the second capacitor is coupled to a second conductive structure. In an example, an interconnect feature includes a continuous and monolithic body of conductive material. In an example, the continuous and monolithic body extends through the second conductive structure, and further extends through the first conductive structure. In an example, the first and second memory cells are dynamic random access memory (DRAM) memory cells.

摘要： An integrated circuit structure comprises one or more backend-of-line (BEOL) interconnects formed over a first ILD layer. An etch stop layer is over the one or more BEOL interconnects, the etch stop layer having a plurality of vias that are in contact with the one or more BEOL interconnects. An array of BEOL thin-film-transistors (TFTs) is over the etch stop layer, wherein adjacent ones of the BEOL TFTs are separated by isolation trench regions. The TFTs are aligned with at least one of the plurality of vias to connect to the one or more BEOL interconnects, wherein each of the BEOL TFTs comprise a bottom gate electrode, a gate dielectric layer over the bottom gate electrode, and an oxide-based semiconductor channel layer over the bottom gate electrode having source and drain regions therein. Contacts are formed over the source and drain regions of each of BEOL TFTs, wherein the contacts have a critical dimension of 35 nm or less, and wherein the BEOL TFTs have an absence of diluted hydro-fluoride (DHF).

摘要： An interconnect structure is disclosed. The interconnect structure includes a first metal interconnect in a bottom dielectric layer, a via that extends through a top dielectric layer, a metal plate, an intermediate dielectric layer, and an etch stop layer, and a metal in the via to extend through the top dielectric layer, the metal plate, the intermediate dielectric layer and the etch stop layer to the top surface of the first metal interconnect. The metal plate is coupled to an MIM capacitor that is parallel to the via. The second metal interconnect is on top of the metal in the via.
