Abstract:
1. Process for selective deposition of material on electrodes of chips made from a single substrate, including: a) forming a plurality of chips on a substrate wherein, each chip of the plurality of chips comprises a plurality of electrodes on which selective material depositions have to be made, address pads, and an address area containing a programmed address of the chip, wherein the address area is connected to the address pads and capable of recognizing the address of said chip to put it in an active state if the chip address is contained in a command word received on the address pads, and establishing electrical connections to connect the address pads and the plurality of electrodes on each chip to the address area for activation of the chips and polarization of the electrodes, addressing the chips and electrodes on which a first material is to be deposited, comprising: depositing said first material simultaneously on the electrodes concerned by electrodeposition, repeating said addressing and depositing steps as many times as necessary to make material depositions on the other electrodes.
