Abstract: A vertical three dimensional (3D) microstrip line structure for improved tunable characteristic impedance, methods of manufacturing the same and design structures are provided. More specifically, a method is provided that includes forming a first microstrip line structure within a back end of the line (BEOL) stack. The method further includes forming a second microstrip line structure separated from the BEOL stack by a predetermined horizontal distance.

Abstract: Methods, wires, and apparatus for use in cutting (e.g., slicing) hard, brittle materials is provided. The wire can be a super-abrasive wire that includes a wire core and super-abrasive particles bonded to the wire core via a metal bonding layer. This wire, or another type of wire, can be used to slice workpieces useful for producing wafers. The workpieces can be aligned within a holder to produce wafers using the device and methods presently provided. The holder rotates about its central axis, which translates to workpieces moving in orbit around this axis. A single abrasive wire, or multiple turns of wire stretched tightly between wire guides, is then contacted with the rotating holder to slice the workpieces.
