摘要:
The present invention provides a method of manufacturing a metal silicide electrode (100) for a semiconductor device (110). The method comprises depositing by physical vapor deposition, germanium atoms (120) and transition metal atoms (130) to form a metal-germanium alloy layer (140) on a semiconductor substrate (150). The metal-germanium alloy layer and the semiconductor substrate are reacted to form a metal silicide electrode. Other aspects of the present invention include a method of manufacturing an integrated circuit (400).

The present invention provides a method of manufacturing a metal silicide electrode (100) for a semiconductor device (110). The method comprises depositing by physical vapor deposition, halogen atoms (120) and transition metal atoms (130) to form a halogen-containing metal layer (140) on a semiconductor substrate (150). The halogen-containing metal layer and the semiconductor substrate are reacted to form a metal silicide electrode. Other aspects of the present invention include a method of manufacturing an integrated circuit (400) comprising the metal silicide electrode.
摘要:
Methods are disclosed that fabricating semiconductor devices with high-k dielectric layers. The invention removes portions of deposited high-k dielectric layers not below gates and covers exposed portions (e.g., sidewalls) of high-k dielectric layers during fabrication with an encapsulation layer, which mitigates defects in the high-k dielectric layers and contamination of process tools. The encapsulation layer can also be employed as an etch stop layer and, at least partially, in comprising sidewall spacers. As a result, a semiconductor device can be fabricated with a substantially uniform equivalent oxide thickness.
