Process for Forming Continuous Copper Thin Films Via Vapor Deposition |
摘要 |
A process for preparing a multi-layer substrate is described herein. In one embodiment, the process provides a multi-layer substrate comprising a first layer and a second layer where the process comprises the steps of providing the first layer comprising a barrier area and a copper area; and depositing the second layer comprising copper onto the first layer wherein the depositing provides the second layer comprising a first thickness ranging from about 20 Angstroms to about 2,000 Angstroms onto the barrier area and a second thickness ranging from about 0 Angstroms to about 1,000 Angstroms onto the copper area in the first layer wherein the first thickness is greater than the second thickness.
