发明名称 Manufacturing method for an integrated semiconductor structure and corresponding integrated semiconductor structure
摘要 The present invention provides a manufacturing method for an integrated semiconductor structure and a corresponding integrated semiconductor structure. The manufacturing method comprises the steps of: providing an integrated circuit substrate having a main surface; providing a dielectric layer on said main surface; providing a via in said dielectric layer, said via exposing a contact area of said integrated circuit substrate; depositing a first liner of Ti on said dielectric layer and said contact area; performing an annealing process such that a Ti silicide region is formed in said contact area from a part of said first liner of Ti and a remaining part of said first liner of Ti is converted into a TiN liner; selectively removing said converted remaining part with respect to said Ti silicide region and said dielectric layer; depositing a second liner of TiN on said dielectric layer and said contact area; and depositing a conductive layer on said second liner of TiN which conductive layer forms a contact in said via and a wiring layer above and in a periphery of said via.
