Claim Text:
1. A fabrication method of a lithium microbattery, comprising the following successive steps: providing a stack of layers successively comprising: etching the first and second materials to form a first pattern made from the first material and a second pattern made from the second material, the second pattern defining an uncovered area and a covered area of the electrolyte layer; etching the uncovered area of the electrolyte layer using the second pattern as etching mask, and eliminating the first pattern; depositing in localized manner a lithium-based layer on the second pattern, the second material being configured such that the lithium atoms diffuse into the second pattern, the lithium-based layer and the second pattern forming a lithium-based second electrode.
