Abstract
A method for forming a lithium-ion type battery including the steps of forming, over an at least locally conductive substrate, an insulating layer having a through opening; successively and conformally depositing a stack comprising a cathode collector layer, a cathode layer, an electrolyte layer, and an anode layer, this stack having a thickness smaller than the thickness of the insulating layer; forming, over the structure, an anode collector layer filling the space remaining in the opening; and planarizing the structure to expose the upper surface of the insulating layer.
