Abstract
Forming a porous layer on a silicon substrate. Forming the porous layer can include placing a first silicon substrate in a solution, where a first electrode is within a threshold distance to an edge of the silicon substrate. It can further include conducting a first current through the silicon substrate, where the first electrode can be positioned relative to the edge allowing for substantially uniform porosification along the edge of the first silicon substrate.
