Filed: 1998-09-01
Granted: 2000-11-21
Abstract: A method of forming a contact via. The present invention comprises a Si-containing first conductive layer, an oxide layer and a photoresist layer. The method comprises etching the oxide layer to form a contact via; using a fluoro-containing oxygen plasma as a formula to peel off the photoresist layer and performing another etching on the bottom of the contact via while peeling off the photoresist layer so that the bottom of the contact via can penetrate deeper into the interior of the oxide layer; depositing a Ti-containing second conductive layer within the contact via, since the thicker bottom of the second conductive layer has penetrated deeper into the interior of the oxide layer, the second conductive layer has only a thinner side wall in direct contact with the first conductive layer, and the distance between the thicker bottom of the second conductive layer and the first conductive layer become larger. Therefore, the influence of the migration of silicon will become smaller thereby obtaining a significant improvement in conductivity.
