Publication number: 20220084840Abstract: 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.Type: ApplicationFiled: November 24, 2021Publication date: March 17, 2022Inventors: David Pain, Andrew Edmonds, Jeffrey Herman, Charles Pateros, Kareemullah Shaik

Publication number: 20220081760Abstract: Process for manufacturing a printhead for a 3D manufacturing system that uses metal electrodeposition to construct parts. The printhead may be constructed by depositing layers on top of a backplane that contains control and power circuits. Deposited layers may include insulating layers and an anode layer that contain deposition anodes that are in contact with the electrolyte to drive electrodeposition. Insulating layers may for example be constructed of silicon nitride or silicon dioxide; the anode layer may contain an insoluble conductive material such as platinum group metals and their associated oxides, highly doped semiconducting materials, and carbon based conductors. The anode layer may be deposited using chemical vapor deposition or physical vapor deposition. Alternatively in one or more embodiments the printhead may be constructed by manufacturing a separate anode plane component, and then bonding the anode plane to the backplane.Type: ApplicationFiled: November 24, 2021Publication date: March 17, 2022Inventors: David Pain, Andrew Edmonds, Jeffrey Herman, Charles Pateros, David Wirth

Patent number: 10947632Abstract: A method of additive manufacturing that deposits material onto a cathode by transmitting current from an anode array through an electrolyte to the cathode; the method uses feedback to control the manufacturing of successive layers of a part. For example, feedback signals may be a map of current across the anode array; this current map may be processed using morphological analysis or Boolean operations to determine the extent of deposition across the layer. Feedback data may be used to determine when a layer is complete, and to adjust process parameters such as currents and voltages during layer construction. Layer descriptions may be preprocessed to generate maps of desired anode current, to manipulate material density, and to manage features such as overhangs. Feedback signals may also trigger execution of maintenance actions during the build, such as replenishment of anodes or removal of films or bubbles.Type: GrantFiled: July 28, 2020Date of Patent: March 16, 2021Assignee: FABRIC8LABS, INC.Inventors: David Pain, Andrew Edmonds, Jeffrey Herman, Charles Pateros, Kareemullah Shaik

Patent number: 10724146Abstract: Printhead for a 3D manufacturing system that uses metal electrodeposition to construct parts; embodiments utilize a grid of anodes to achieve high quality parts with features that may be small and detailed. To support grids with thousands or millions of anodes, the printhead may use matrix control with row and column drivers similar to display backplanes. Unlike display backplanes where the design goal is to display images using minimal current, the printhead may be optimized for high current density for fast electrodeposition, and for anode longevity. Current density may exceed 1000 mA per cm-squared, at least an order of magnitude greater than that of display backplanes. Anode longevity may be enhanced by using relatively large anodes compared to the grid pitch of the printhead, by lengthening the conductive paths through anodes, or both. Embodiments may be constructed by adding anode and insulation layers on top of matrix-controlled switching circuits.Type: GrantFiled: February 19, 2020Date of Patent: July 28, 2020Assignee: FABRIC8LABS, INC.Inventors: David Pain, Andrew Edmonds, Jeffrey Herman, Charles Pateros, David Wirth

Patent number: 8909961Abstract: Briefly, a method and apparatus adjusts the power consumption level of an integrated circuit by dynamically scaling the clock frequency based on the real-time determined power consumption level. In one example, the method and apparatus changes an actual clock frequency of the integrated circuit to an effective clock frequency based on the maximum clock frequency and the difference between the threshold power consumption level and the actual power consumption level of the integrated circuit in the previous sampling interval. In one example, an effective clock frequency of the integrated circuit in the current sampling interval is determined. In one example, the difference between the maximum and effective clock frequencies in the current sampling interval is proportional to the difference between the threshold and actual power consumption levels in the previous sampling interval. The actual clock frequency of the integrated circuit is changed to the determined effective clock frequency.Type: GrantFiled: November 29, 2011Date of Patent: December 9, 2014Assignees: ATI Technologies ULC, Advanced Micro Devices, Inc.Inventors: Jeffrey Herman, Krishna Sitaraman, Jia An Huang, Stephen D.
