Abstract: An in-situ method for changing surface features of a metal workpiece. An electrically conductive workpiece is immersed in a bath containing an electrolyte solution devoid of ions corresponding to the workpiece. A counter electrode is immersed in the bath. An electric power supply is connected to the workpiece and the counter electrode. An electric current is passed in a first direction between the workpiece and the counter electrode, while the workpiece serves as an anode. The electric current polarity is reversed to pass the electric current in a second direction between the metallic workpiece and the electrode, while the workpiece serves as a cathode. The electric current polarity in the first direction drives ions from the workpiece into the electrolyte solution, and the electric current polarity in the second direction plates the ions onto the workpiece in the same bath.

Abstract: Described herein are electrochemical-additive manufacturing methods and systems using such methods. A method comprises depositing a material onto a deposition electrode by flowing a current between that deposition electrode and each of multiple individually-addressable electrodes, forming an electrode array. These currents are independently controlled based on a target map and using deposition control circuits, each coupled to one individually-addressable electrode. The target map is generated by a system controller based on various characteristics of the system (e.g., the performance of each deposition control circuit and/or individually-addressable electrode, electrolyte composition) and the desired characteristics of the deposited material (e.g., deposition location, uniformity, morphology). Furthermore, when the deposition electrode and the electrode array move relative to each other, the system controller dynamically updates the target map based on their relative positions.

Abstract: It is determined whether an imaginary component at a predetermined frequency of an alternating current impedance is equal to or more than a preliminarily set film-formable value or not. The metallic coating is formed in a state where the substrate is pressed by the solid electrolyte membrane when the imaginary component is equal to or more than the film-formable value in the determining. The metallic coating is formed in a state where the pressing of the substrate by the solid electrolyte membrane is released to separate the solid electrolyte membrane from the substrate, the solid electrolyte membrane is re-tensioned with a constant tensile force, and subsequently, the substrate is pressed by the re-tensioned solid electrolyte membrane when the imaginary component is smaller than the film-formable value in the determining.

Abstract: Carbon nanotube (CNT) agglomerates can be aligned along the field lines between adjacent electrodes to form conductive bridges. The present invention is directed to a stepwise process of dielectrophoretic deposition of CNTs to form conducting bridges between adjacent electrodes spanning lengths over 50 microns. The CNT bridges are permanently secured using electrodeposition of the conducting polymer polypyrrole. Morphologies of the CNT bridges formed within a frequency range of 1 kHz and 10 MHz are employed and explained as a consequence of interplay between dielectrophoretic and electroosmotic forces. Postdeposition heat treatment increases conductivity of CNT bridges likely due to solvent evaporation and resulting surface tension inducing better contact between CNTs.

Abstract: A system and method of using electrochemical additive manufacturing to add interconnection features, such as wafer bumps or pillars, or similar structures like heatsinks, to a plate such as a silicon wafer. The plate may be coupled to a cathode, and material for the features may be deposited onto the plate by transmitting current from an anode array through an electrolyte to the cathode. Position actuators and sensors may control the position and orientation of the plate and the anode array to place features in precise positions. Use of electrochemical additive manufacturing may enable construction of features that cannot be created using current photoresist-based methods. For example, pillars may be taller and more closely spaced, with heights of 200 ?m or more, diameters of 10 ?m or below, and inter-pillar spacing below 20 ?m. Features may also extend horizontally instead of only vertically, enabling routing of interconnections to desired locations.
