Focused Electric Field Imprinting (FEFI) provides a focused electric field to guide an unplating operation and/or a plating operation to form very fine-pitched metal patterns on a substrate. The process is a variation of the electrochemical unplating process, wherein the process is modified for imprinting range of patterns of around 2000 microns to 20 microns or less in width, and from about 0.1 microns or less to 10 microns or more in depth. Some embodiments curve a proton-exchange membrane whose shape is varied using suction on a backing fluid through a support mask. Other embodiments use a curved electrode. Mask-membrane interaction parameters and process settings vary the feature size, which can generate sub-100-nm features. The feature-generation process is parallelized, and a stepped sequence of such FEFI operations, can generate sub-100-nm lines with sub-100-nm spacing. The described FEFI process is implemented on copper substrate, and also works well on other conductors.
摘要:
Systems and methods for plating and/or etching of hard-to-plate metals are provided. The systems and methods are designed to overcome the deleterious effect of superficial coating or oxide layers that interfere with the plating or etching of certain metal substrates. The systems and methods involve in situ removal of coating materials from the surfaces of the metal substrates while the substrates are either submerged in plating or etching solutions, or are positioned in a proximate enclosure just prior to submersion in the plating or etching solutions. Further, the substrates can be in contact with a suitable patterning mask to obtain patterned oxide-free regions for plating or etching. This in situ removal of coating layers may be achieved by pulse heating or photoablation of the substrate and the inhibiting coating layers. Electrical energy or laser light energy may be used for this purpose. Additionally or alternatively, the coating materials may be removed by mechanical means.

Provided is an electroplating apparatus including: a copper electrode plate that is disposed with a gap from an upper surface of an insulating substrate on which seed electrodes are formed; a driving unit that makes the copper electrode plate move along a rectilinear line; a power supply that applies electric current between the copper electrode plate and each of the seed electrodes; and spacers that are provided on the lower surface of the copper electrode plate to thereby make an electrolyte stay by surface tension between the copper electrode plate and the insulating substrate, and that maintains the gap between the copper electrode plate and the insulating substrate so that the electrolyte may move together with the copper electrode plate. Accordingly, a uniform copper film can be formed on the surface of a large substrate.
