An apparatus and method for electrochemically depositing a unitary layer structure using a reactor configured to contain an electrolyte solution with an anode array containing a plurality of independently electrically controllable anodes arranged in a two-dimensional array, a cathode, an addressing circuit for receiving a signal containing anode address data and for outputting a signal causing an anode array pattern; and, a controller, in communication with the addressing circuit and the anode array, configured to electrically control each anode in the anode array to cause an electrochemical reaction at the cathode that deposits a unitary layer structure according to the anode array pattern signal.

A basic structural body for constructing heat dissipation device and a heat dissipation device are disclosed. The heat dissipation device includes a first basic structural body having a wick structure formed on one side surface thereof; and the first basic structural body and the wick structure are structural bodies formed layer by layer. Two pieces of first basic structural bodies can be correspondingly closed together to construct a heat dissipation device internally defining an airtight chamber. In this manner, the heat dissipation device can be designed in a more flexible manner.

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 μm or more, diameters of 10 μm or below, and inter-pillar spacing below 20 μm. Features may also extend horizontally instead of only vertically, enabling routing of interconnections to desired locations.
