On-chip interconnections comprise a multilevel structure of fine wiring located on the top of the transistor circuitry of logic or memory chips, whose role is to connect circuits together as shown in Fig. 1. To avoid significant degradation of circui

The need for recording heads to write on high-coercivity media at high frequencies has created new requirements for the write-head material that cannot be met by Ni80Fe20, the nickel-iron alloy traditionally used in the fabrication of the device. Ele

The hard work of three leading researchers was recently interrupted when I asked them to ponder the following question: “What, in your view, is an exciting, major development in electrodeposition over the last five years?” Believe it or not, they

Electrochemical fabrication of PbSn C4s (controlled collapse chip connection) offers significant cost, reliability, and environmental advantages over the currently employed evaporation technology. A continuous seed layer is required for through-mask

Underpotential deposition of Pb or Sn on Cu can be used to produce electroplated Cu‐Pb and Cu‐Sn alloys, with small amounts of alloyed Pb and Sn, from acid solutions that do not contain complexants. Such alloys are of interest as possible on‐ch

A technique that makes use of a rotating ring-disk electrode has been developed for the composition determination of NiCo alloys. Because of its low cost and ease of use, the technique is ideally suited for the study of NiCo plating solutions. Follow

A rotating ring-disk stripping technique has been used to analyze Sn-Pb alloys plated from methane sulfonic acid solutions with and without a proprietary additive and to construct associated current-potential curves. The deposition of both pure Sn an

A model has been developed to predict current distribution in electrodeposition onto substrates that contain lithographic patterns. The aim of the work was to understand the strong effects that substrate patterning can exert on the thickness distribu
