Abstract:
Se proporcionan estructuras de interconexión que tienen capuchones dieléctricos autoalineados. Se forma al menos un nivel de metalización sobre un sustrato. Un capuchón o tapa dieléctrica es depositada selectivamente sobre el nivel de metalización.
Abstract:
PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor device capable of attaining high reliability and a high production yield by eliminating a void generation portion in a liner/copper interface. SOLUTION: The method of forming a diffusion barrier used for manufacturing the semiconductor device includes a step for depositing an iridium-doped tantalum-based barrier layer on a pattern-formed intermediate dielectric (ILD) layer by a physical vapor deposition (PVD) process, and the barrier layer is deposited to form the barrier layer into amorphous structure as a result, at least 60% of an iridium concentration in terms of atomic weight.
