Patent ID: 8530120

Claim:
A method for patterning a second layer of a workpiece in a direct write machine in the manufacturing of a multilayer stack, the workpiece having a first layer with a plurality of electrical components in the form of dies that are arbitrarily placed, each die having connection points whereof some are to be connected between the dies, a selection of said dies being associated with a first pattern wherein different zones comprising connection points of dies placed in the first layer are associated with different requirements on alignment; the method comprising the steps of: a. detecting sacred zones in the first pattern that have a high requirement on alignment to selected features of the stack or to the placed dies; b. detecting stretch zones of the first pattern that are allowed to have a lower requirement on alignment to other features of the stack; c. transforming the first pattern by calculating adjusted first pattern data comprising transformation of the original circuit pattern such that: i. connection points in adjacent sacred zones are aligned within a pre-settable alignment deviation parameter; and such that ii. deviations between the positions of corresponding connection points in the sacred zones are compensated for in the pattern for connection points of the stretch zones; d. writing a pattern on a second layer of the workpiece according to the adjusted first pattern data.
