Lithographic apparatuses suitable for complementary e-beam lithography (CEBL) are described. In an example, a blanker aperture array (BAA) for an e-beam tool includes a first column of openings along a first direction and having a pitch. Each opening of the first column of openings has a dimension in the first direction. The BAA also includes a second column of openings along the first direction and staggered from the first column of openings. The second column of openings has the pitch. Each opening of the second column of openings has the dimension in the first direction. A scan direction of the BAA is along a second direction orthogonal to the first direction. The openings of the first column of openings overlap with the openings of the second column of openings by at least 5% but less than 50% of the dimension in the first direction when scanned along the second direction.
