Title (EN) DICING METHOD
(FR) PROCEDE DE DECOUPAGE EN DES
Abstract: front page image
(EN)The dicing method comprises the steps of providing a substrate (1) of semiconductor material, the substrate having a main surface (10), where integrated components (3) of chips (13) are arranged, and a rear surface (11) opposite the main surface, fastening a first handling wafer above the main surface, thinning the substrate at the rear surface, and forming trenches (20) penetrating the substrate and separating the chips by a single etching step after the substrate has been thinned.
(FR)L'invention concerne un procédé de découpage en dés, qui comporte les étapes consistant à : fournir un substrat (1) de matériau semi-conducteur, le substrat comportant une surface principale (10) sur laquelle des composants intégrés (3) de puces (13) sont aménagés, et une surface arrière (11), opposée à la surface principale ; fixer une première plaquette de manipulation au-dessus de la surface principale ; amincir le substrat au niveau de la surface arrière ; et former des tranchées (20) pénétrant dans le substrat et séparer les puces par la mise en oeuvre d'une seule étape de gravure, après que le substrat a été aminci.
