Abstract

A method for forming a lithium-ion type battery, including the successive steps of: forming, in a substrate, a trench; successively and conformally depositing a stack including a cathode collector layer, a cathode layer, an electrolyte layer, and an anode layer, this stack having a thickness smaller than the depth of the trench; forming, over the structure, an anode collector layer filling the space remaining in the trench; and planarizing the structure to expose the upper surface of the cathode collector layer.
