TL;DR: 3D-technology scaling faces several technical challenges, including as the number of WL stacks increases the channel-hole etch process becomes a limit, since the total WL-mold height increases.
Journal ArticleDOI
The Effects of Bath Composition on the Morphologies of Electroless Nickel Under-Bump Metallurgy on Al Input/ Output Pad
TL;DR: In this paper, the electroless nickel plating on an aluminum input/output (I/O) pad was investigated and the relationship between aluminum dissolution and the ratio of zinc and NaOH was investigated.
