发明名称 METHOD TO IMPROVE METAL DEFECTS IN SEMICONDUCTOR DEVICE FABRICATION
摘要 The invention, in one aspect, provides a method of manufacturing a semiconductor device. This method includes providing a semiconductor substrate and depositing a metal layer over the semiconductor substrate that has an overall thickness of about 1 micron or greater. The metal layer is formed by depositing a first portion of the thickness of the metal layer, which has a compressive or tensile stress associated therewith over the semiconductor substrate. A stress-compensating layer is deposited over the first portion, such that the stress-compensating layer imparts a stress to the first portion that is opposite to the compressive or tensile stress associated with the first portion. A second portion of the thickness of the metal layer is then deposited over the stress-compensating layer.
