Patent ID: 8594824

Claim:
A method for patterning a layer of a first workpiece in a direct write machine in the manufacturing of a multilayer stack, where the direct write machine is provided with a coordinate system for controlling write operations on a first layer of the first workpiece having a plurality of dies placed thereon, wherein the plurality of dies each have a plurality of connection points; the method comprising: retrieving first circuit pattern data of a first circuit pattern representing at least one first sub-area of said first layer of the first workpiece, wherein the at least one first sub-area is associated with, and is covering, at least one die of the plurality of dies of the first layer; retrieving second circuit pattern data of a second circuit pattern representing at least a second sub-area associated with a plurality of connection points of one or a plurality of specific features of a second layer(s), wherein the second layer(s) is one or a plurality of preceding or succeeding layer(s) of the first workpiece and/or one or a plurality of layer(s) in a second workpiece that is to be connected to the first workpiece, and wherein at least one of the plurality of connection points of the at least one die of the first layer is adapted for connecting to at least one of the connection points of the one or plurality of specific features of the second layer(s); determining required first fitting tolerance(s) for adjusting the first circuit pattern at least to the first sub-area of the first layer; determining required second fitting tolerance(s) for adjusting the first circuit pattern so that the connection points of the adjusted first circuit pattern fit to the connection points of at least one second circuit pattern representing the one or plurality of specific features of the second layer(s); preparing adjusted first circuit pattern data that fit the adjusted first circuit pattern to the at least one first sub-area of the first layer within the required first fitting tolerances, and the at least one of the connection points of the at least one die of the first circuit pattern representing the at least one first sub-area to the at least one of the connection points of the one or plurality of specific features of the at least one second circuit pattern within the second fitting tolerance(s); and writing a pattern on the first workpiece according to the adjusted first circuit pattern data.
