Abstract:
Various embodiments provide improved processes and systems that produce a barrier layer with decreasing nitrogen concentration with the increase of film thickness. A barrier layer with decreasing nitrogen concentration with film thickness allows the end of barrier layer with high nitrogen concentration to have good adhesion with a dielectric layer and the end of barrier layer with low nitrogen concentration (or metal-rich) to have good adhesion with copper. An exemplary method of depositing a barrier layer on an interconnect structure is provided. The method includes (a) providing an atomic layer deposition environment, (b) depositing a barrier layer on the interconnect structure with a first nitrogen concentration during a first phase of deposition in the atomic layer deposition environment. The method further includes (c) continuing the deposition of the barrier layer on the interconnect structure with a second nitrogen concentration during a second phase deposition in the atomic layer deposition environment.
Abstract:
PROBLEM TO BE SOLVED: To provide a system and a method for preventing the transfer of accumulated fluid to semiconductor wafers during cleaning operations. SOLUTION: When a wafer 110 is supported by a plurality of self-draining edge wheels 120, any fluid contacting the edge wheels 120 is channeled away from the wafer 110 towards a bottom surface of each of the edge wheels 120. The channeling occurs by manufacturing the bottom portions of the edge wheels 120 to have different configurations. The different configurations enhance fluid channeling away from the wafer 110. To further prevent fluid from wetting a bottom surface of the edge wheels 120, an edge wheel dryer 140 can be positioned proximately adjacent to at least one edge wheel 120 to suction the fluid away from the bottom surface by using a vacuum channel of the edge wheel dryer 140.

Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus and method for reducing contamination capable of achieving lower costs, and more sufficiently supplying and removing fluid to and from a wafer surface. SOLUTION: Processing fluid is supplied to the wafer surface and almost instantly removed with fluid on a wafer by a vacuum provided by an outlet 304. The processing fluid is supplied to the wafer surface such that the processing fluid is present in an area between a proximity head and the wafer surface for a moment with the given fluid on the wafer surface. In this processing, a meniscus 116 is formed and the boundary of the meniscus 116 acts as an IPA/processing fluid interface 118. Therefore, the meniscus 116 is supplied to the surface and practically acts as a fixed flow removed with the given fluid on the wafer surface. The fluid is almost instantly removed from the wafer surface area during drying, so that the formation of droplets of the fluid is prevented in the wafer surface area during drying and the probability of contamination on a wafer 108 is reduced.
