Abstract
The described embodiments relate to a slotted substrate and methods of forming same. One exemplary method patterns a hardmask on a first substrate surface sufficient to expose a first area of the first surface and forms a slot portion in the substrate through less than an entirety of the first area of the first surface. The slot portion has a cross-sectional area at the first surface that is less than a cross-sectional area of the first area. After forming the slot portion, the method etches the substrate to remove material from within the first area to form a fluid-handling slot.
