Multi-layer structures are electrochemically fabricated by depositing a first material, selectively etching the first material (e.g. via a mask), depositing a second material to fill in the voids created by the etching, and then planarizing the depositions so as to bound the layer being created and thereafter adding additional layers to previously formed layers. The first and second depositions may be of the blanket or selective type. The repetition of the formation process for forming successive layers may be repeated with or without variations (e.g. variations in: patterns; numbers or existence of or parameters associated with depositions, etchings, and or planarization operations; the order of operations, or the materials deposited). Other embodiments form multi-layer structures using operations that interlace material deposited in association with some layers with material deposited in association with other layers.

Disclosed methods reduce the discontinuities between individual layers of a structure that are formed at least in part using electrochemical fabrication techniques. Discontinuities may exist between layers of a structure as a result of up-facing or down-facing regions defined in data descriptive of the structure or they may exist as a result of building limitations, e.g., limitations that result in non-parallel orientation between a building axis and sidewall surfaces of layers. Methods for reducing discontinuities may be applied to all regions or only to selected regions of the structure. Methods may be tailored to improve the accuracy between an original design of the structure and the structure as fabricated or they may simply be used to smooth the discontinuities between layers. Methods may include deposition operations that selectively favor filling of the discontinuities and / or etching operations that selectively favor removal of material from protrusions that define discontinuities.
