Abstract:
1. A modulator arrangement configured for maskless lithography or printing applications, the modular arrangement comprising: at least two array tiles of modulators, each array tile having a substantially equal modulator pitch and being configured to form a plurality of rows, each row extending in a first direction, and a plurality of columns, each column extending in a second direction, wherein the first direction and the second direction are substantially perpendicular to each other, wherein two adjacent array tiles are separated by wherein each of the plurality of rows in each array tile includes a first number of modulators distributed in the first direction, each of the plurality of columns in each array tile includes a second number of modulators distributed in the second direction, the at least two array tiles are configured to move along a scan direction at an angle between the first direction and the second direction, and the scan direction is chosen to form a continuous lithographic swath having a swath width in the second direction, and wherein the second displacement is equal to the first displacement divided by a product of a total number of array tiles and the first number of modulators.
