Abstract We compare different dc current-based integrated capacitance measurement techniques in terms of their applicability to modern CMOS technologies. The winning approach uses quadrature detection to measure mutual Front-End-Of-Line (FEOL) and Back-End-Of-Line (BEOL) capacitances. We describe our implementation of this approach, Quadrature-clocked Voltage-dependent Capacitance Measurements (QVCM), and its application to 45 nm node BEOL: wire capacitance variability measurements for analog design, and capacitive test structure to measure the effect of metal pattern density on Chemical-Mechanical Polishing (CMP) and Reactive Ion Etching (RIE).

Abstract As technology nodes continue to shrink, resistive opens have become increasingly difficult to detect using conventional methods such as AVC and PVC. The failure isolation method, Electron Beam Absorbed Current (EBAC) Imaging has recently become the preferred method in failure analysis labs for fast and highly accurate detection of resistive opens and shorts on a number of structures. This paper presents a case study using a two nanoprobe EBAC technique on a 28nm node test structure. This technique pinpointed the fail and allowed direct TEM lamella.

Abstract Modifications directly to a transistor’s source/drain and polysilicon gate through the backside of a SOI device were made. Contact resistance data was obtained by creating contacts through the buried oxide layer of a manufactured test structure. A ring oscillator circuit was modified and the shift in oscillator frequency was measured. Finally, cross section images of the FIB created contacts were presented in the paper to illustrate the entire process.
