Patent ID: 8859312

Claim:
A method of manufacturing an integrated circuit (IC) for driving a flexible display, comprising: depositing a pattern of first features in a first layer on a flexible substrate, wherein said first features comprise one or more of data lines, interconnects for thin film transistors, flexible connectors, test patterns, or alignment marks and wherein said first features comprise: a first set of first features regularly repeating in only a first direction in the plane of the substrate; and a second set of first features regularly repeating in only a second direction in the plane of the substrate, the second direction orthogonal to the first direction; depositing a pattern of repetitive second features as an array in a second layer on said first layer, wherein said second features comprise one or more of source, drain, or gate electrodes for thin film transistors and wherein said depositing comprises depositing a material and patterning said material using a step and repeat mask-based deposition process comprising: depositing and patterning a first set of the second features in a first area of the second layer; translating said substrate from a first position at which said first set of the second features is depositable to a second position at which a second set of the second features is depositable in a second area of the second layer; depositing and patterning said second set of the second features in said second area; and repeating said step and repeat deposition process to deposit said second features; aligning said second layer and said first layer so as to allow electrical coupling between said first features and said second features, wherein the mask is configured such that the first area is smaller than the entire array and the second area is smaller than the entire array wherein each of said first and said second areas are locally aligned to apply local distortion compensation during the deposition of said pattern of repetitive second features to enable said alignment.
