Abstract

A pick-up structure for a memory device and method for manufacturing memory device are provided. The pick-up structure includes a substrate and a plurality of pick-up electrode strips. The substrate has a memory cell region and a peripheral pick-up region adjacent thereto. The pick-up electrode strips are parallel to a first direction and arranged on the substrate in a second direction. The second direction is different from the first direction. Each pick-up electrode strip includes a main part in the peripheral pick-up region and an extension part extending from the main part to the memory cell region. The main part is defined by fork-shaped patterns of a first mask layer. The extension part has a width less than that of the main part, and the extension part has a side wall surface aligned with a side wall surface of the main part.
