Abstract
La présente invention se rapporte à un procédé de formation d’un trou auto-aligné dans un substrat afin de former un passage d’alimentation en fluide, le procédé comprenant les étapes consistant à : former initialement une couche isolante sur un premier côté d’un substrat ayant deux côtés opposés; et former un élément sur la couche isolante; graver ensuite une ouverture dans la couche isolante, de sorte que l’ouverture soit physiquement alignée sur l’élément situé sur la couche isolante; et recouvrir l’élément d’une couche de matériau de protection. Le modelage de la couche de matériau de protection exposera l’ouverture dans la couche isolante. La gravure sèche depuis le premier côté du substrat forme un trou borgne d’alimentation dans le substrat correspondant à l’emplacement de l’ouverture dans la couche isolante, le trou borgne d’alimentation comprenant un fond. Par la suite, on meule un second côté du substrat et on le grave sur banchet pour former un trou dans tout le substrat.
