Claim 0:
1. A method for coating chips resting, by a rear face of the chips opposite to a front face of the chips, on a main face of a support substrate, the chips being separated from each other by an inter-chip space, the method comprises:
a) forming a photosensitive coating film covering the front faces and the inter-chip spaces, the photosensitive coating film having either a negative tone or a positive tone, and, at the end of step a), is of a thickness E less than or equal to a height H measured between the main face and the front face of a chip,
b) a first photolithographic sequence which comprises an insolation b1), and a dissolution b2), said first photolithographic sequence leading to a partial removal of the photosensitive coating film so as to maintain said photosensitive coating film exclusively at the inter-chip spaces.
