AbstractWe have developed a novel microwave near-field scanning probe technique for non-contact measurement of the dielectric constant of low-k films. The technique is non-destructive, noninvasive and can be used on both porous and non-porous dielectrics without any sample preparation. The probe has a few-micron spot size, which makes the technique well suited for real time low-k metrology on production wafers. For dielectrics with k<4 the precision and accuracy are better than 2% and 5%, respectively. Results for both SOD and CVD low-k films are presented and show excellent correlation with Hg-probe measurements. Results for k-value mapping on blanket 200mm wafers are presented as well.

Abstract We demonstrate the use of a near-field scanned microwave probe (NSMP) for failure analysis (FA) of parametric defects in Cu/low-k interconnect that leave no physical remnant (sometimes referred to as “non-visual defects”). This technique is rapid, quantitative, non-contact, and provides direct electrical measurements.

AbstractThe investigation of an alternate approach to nondestructive, nanoscale mechanical imaging for IC interconnect structures is reported. This approach utilizes a heterodyne interferometer based on a scanning probe microscope, also referred to as heterodyne force microscopy (HFM). This interferometer is sensitive to the relative phase difference of the two ultrasonic excitations due to spatial variations in the sample viscoelastic response and enables near-field, phase-sensitive imaging. Proof-of-feasibility demonstrations of this technique are presented for ultrasonic phase-imaging of Al/low-k interconnect structures. Spatial resolution <10 nm is demonstrated.
