Abstract

L'invention concerne un laser utilisé pour éliminer des contaminants de surface, tels que graisse, cire et résidus de résine, d'un moule utilisé sur des outils d'encapsulation de semiconducteurs. Le procédé d'élimination des contaminants au moyen d'un laser consiste à diriger un faisceau laser sur la surface du moule portant les contaminants. Le laser est envoyé sous forme d'impulsion de courte durée. Des impulsions multiples peuvent être nécessaires afin d'éliminer complètement les contaminants. Etant donné que la superficie couverte par chaque impulsion est habituellement très inférieure à la superficie totale de la surface du moule, le laser doit balayer la surface du moule jusqu'à ce que celle-ci ait été entièrement exposée au laser. Etant donné que la désintégration des contaminants par le laser produit des émanations, il est préférable d'utiliser un aspirateur afin d'éliminer les gaz résiduels et autres déchets.
