Direct Recycling of Copper from Etching to Plating
نویسندگان
چکیده
In the manufacture of printed circuit boards, the copper dissolved during etching can be used to replace the copper needed for plating using a liquid ion-exchange agent. Extraction and stripping studies demonstrated the feasibility. The quality of the etchant was not affected by the presence of the ion-exchange agent. Good-quality deposits were plated from the stripping solution with a current efficiency of 100 percent.

Nanowires fine tunable fabrication by varying the concentration ratios, the etchant and the plating spices in metal-assisted chemical etching of silicon wafer.
The metal-assisted chemical etching (MACE) was used to synthesis silicon nanowires. The effect of etchant concentration, etching and chemical plating time and doping density on silicon nanowires length were investigated. It is held that the increasing of HF and H2O2 concentrations lead to etching rate increment and formation of wire-like structure. The results show that, the appropriate ratio o...
متن کاملFormation of a Low Ohmic Contact Nickel Silicide Layer on Textured Silicon Wafers Using Electroless Nickel Plating
This paper presents a low cost process for fabrication of high efficiency silicon-based solar cells from front side ARC patterning through contact line metallization. This process utilizes a screen printable etch resist to define the contact pattern and a wet etching solution to remove the exposed ARC layer. The metallization stack for the contact line pattern consists of a nickel silicide ohmi...
متن کاملAspect-Ratio-Dependent Copper Electrodeposition Technique for Very High Aspect-Ratio Through-Hole Plating
Copper electrodeposition in high-aspect-ratio through-holes micromachined by deep reactive ion etching is one of the most essential processes for fabricating through-wafer interconnects, which will be used in developing future generation high-speed, compact 3D microelectronic devices. Although copper electrodeposition is a well-established process, completely void-free electroplating in very de...

متن کاملBi/In Bimetallic Thermal Resists for Microfabrication, Photomasks and Micromachining Applications
Bilayer Bi/In thin films form thermal resists with many new microfabrication and micromachining applications due to their changed physical, chemical and optical characteristics after laser exposures. Wavelength invariance has been shown from the results of both experiment and Airy Summation optical modeling. The modeling projects bimetallic resist sensitivity to be nearly constant at about ~7 m...
