METHOD FOR COATING CHIPS

A method for coating chips resting, by a rear face opposite to a front face, on a main face of a support substrate, and separated from each other by an inter-chip space, includes a step of forming a photosensitive coating film covering the front faces and the inter-chip spaces. The method further in...

Beschreibung
Zusammenfassung:	A method for coating chips resting, by a rear face opposite to a front face, on a main face of a support substrate, and separated from each other by an inter-chip space, includes a step of forming a photosensitive coating film covering the front faces and the inter-chip spaces. The method further includes a first photolithographic sequence which comprises an insolation sub-step, and a dissolution sub-step. The sequence leads to a partial removal of the photosensitive coating film so as to maintain the film exclusively at the inter-chip spaces and, advantageously recessed relative to the front faces.
