System and method for determining hybrid-manufacturing process plans for integrated circuits based on satisfiability modulo difference logic solver

One embodiment of the present disclosure provides a system for determining a hybrid-manufacturing plan for manufacturing an integrated circuit (IC). During operation, the system can obtain a set of hybrid-manufacturing constraints for manufacturing the IC. The set of hybrid-manufacturing constraints can include a set of primitives, a set of atoms, and an atom end-state vector. An atom can correspond to a unit of spatial volume of the IC. A primitive can represent an additive, subtractive, or a mixed manufacturing process corresponding to one or more atoms of the IC. Next, the system can determine a plurality of feasible hybrid-manufacturing plans based on the set of manufacturing constraints. Each feasible hybrid-manufacturing plan can represent an ordering of the set of primitives that satisfies the atom end-state vector. The system can then determine costs for manufacturing the IC using the plurality feasible hybrid-manufacturing plans. The system can determine, based on the costs, an optimized hybrid-manufacturing plan for manufacturing the IC.

The present invention discloses a surface tension driven flexible electronics transfer printing method which uses a surfactant liquid membrane or a surfactant bubble as a transfer printing stamp, to realize the transfer printing of an electronic device with nanometer/micron/submillimeter thickness. A process of transfer printing is transparent and visible in a what you see is what you get manner to realize the accurate positioning of the electronic device. A local load technology is introduced, which is suitable for arbitrary complex curved substrate to realize diverse transfer printing. The electronic device can be transfer-printed to an application substrate with extremely-low interfacial adhesion, without the requirement for the strong and weak adhesion switching strategy of the traditional transfer printing. An unbearable electronic device membrane can be transfer-printed to an fragile receiving substrate with no loss or low loss, without the introduction of pre-pressure.

METHOD FOR FULL FILLING INTER-LAYER BLIND HOLE OF HDI RIGID-FLEX LAMINATE WITH COPPER

A method for copper filling-up of blind vias in HDI rigid-flex PCB is provided which includes the steps of: 1) performing a copper reduction on a single side of a double sided copper-clad laminate; 2) drilling blind vias with inverted trapezoidal shape in a side of the double sided copper-clad laminate being copper reduced by laser; 3) cleaning via walls and the via bottoms of the blind vias to remove the residues left during the drilling process; 4) depositing metallic copper layers on surfaces of the via walls and the via bottoms of the blind vias; 5) filling the blind vias with copper after the blind vias being deposited by metallic copper layer. The copper filling-up of the blind vias in the HDI rigid-flex PCB is achieved, leading to decreased cost of equipment investment and improved production efficiency and benefits.
