Abstract: Dynamic pattern transfer printing systems and method are provided, which decouple the design of the trench patterns on a source substrate for pattern transfer printing, from the resulting metallic paste lines patterns transferred to a receiving substrate, such as PV cells. The receiving substrate may be moved forward (along the scanning direction of the laser illumination used to transfer the paste from the trenches onto the receiving substrate) to reduce the pattern pitch with respect to the source substrate, and/or the receiving substrate may be moved backward (against the scanning direction) to increase the pattern pitch with respect to the source substrate. For example, dynamic pattern transfer printing may be used to accommodate different widths of the substrates for more effective pattern transfer, and/or to enable one-to-many pattern transfer technologies with high wafer throughput. Also, pattern transfer sheet with separate multiple groups of trenches are provided.

Abstract: Pattern transfer sheets, methods of monitoring pattern transfer printing, and pattern transfer printing systems are provided, for monitoring and adjusting laser illumination used for transferring paste patterns from trenches on the sheets onto a substrate such as electronic circuitry and/or solar cell substrates. Pattern transfer sheets comprise, outside the pattern, (i) trace mark(s) configured to receive the printing paste, aligned to the trenches and are wider than the width of the illuminating laser beam—to detect misalignment of paste release from within the trace mark(s) and/or (ii) working window marks configured to receive the printing paste, set at specified offsets with respect to specific trenches, with different working window marks set at different offsets—to correct the effective working window by adjusting the power of the laser beam.

Abstract: Described are an apparatus and a method for printing a high aspect ratio and/or specific vertical geometry pattern. The apparatus operates in a multi-pass printing mode and includes one or more paste dispensing mechanism configured to dispense a high viscosity paste to form a pattern on a substrate. At least one paste dispensing mechanism is configured to dispense the paste to a segment of the pattern printed at an earlier pass. The paste is dispensed to the relevant segment of the pattern earlier printed before the paste printed at the earlier made pass is dry or what is termed “wet-on-wet” printing.

Abstract: A method of depositing a material on a receiving substrate, the method comprising: providing a source substrate having a back surface and a front surface, the back surface carrying at least one piece of coating material; providing a receiving substrate positioned adjacent to the source substrate and facing the coating material; and radiating light towards the front surface of the source substrate, to remove at least one piece of the coating material from the source substrate and deposit said removed at least one piece onto the receiving substrate as a whole.

Abstract: Presented is an apparatus for generating a transfer pattern to be used in a transfer printing process. The pattern is generated in a substrate that could be a web substrate and that bears one or more trenches. A filler to be transferred is made to fill the trenches within the web substrate. Upon completion of the trench by filler filling, the substrate, the scraper and the squeegee are translated from the working zone in a synchronized movement, such that in course of the translation movement at least the scraper remains in full contact with the substrate.

Abstract: A method for producing an electrical circuit includes providing a substrate having a first pattern of features and defining a second pattern comprising a net of interconnected circuit elements. Different respective transformation rules are specified for different ones of the circuit elements. The second pattern is modified by applying the respective transformation rules to the circuit elements so as to align the circuit elements with the features in the first pattern, and the modified second pattern is applied to the substrate.
