摘要： Methods and systems for in situ measuring sputtering target erosion are disclosed. The emission of material from the sputtering target is stopped, a distance sensor is scanned across a radial line on the sputtering target. The sputtering chamber contains a controlled environment separate and distinct from the environment outside the chamber, and the controlled environment is maintained during the scanning The resulting distance data is converted into a surface profile of the sputtering target. The accuracy of the surface profile can be less than about ±1 μm. The distance sensor is protected from deposition of the material from the sputtering target. End-of-life for a sputtering target can be determined by obtaining a surface profile of the sputtering target at regular intervals and replacing the sputtering target when the thinnest location on the target as measured by the surface profile is below a predetermined threshold.

摘要： A co-sputter technique is used to deposit In—Ga—Zn—O films using PVD. The films are deposited in an atmosphere including both oxygen and argon. A heater setpoint of about 300 C results in a substrate temperature of about 165 C. One target includes an alloy of In, Ga, Zn, and O with an atomic ratio of In:Ga:Zn of about 1:1:1. The second target includes a compound of zinc oxide. The films exhibit the c-axis aligned crystalline (CAAC) phase in an as-deposited state, without the need of a subsequent anneal treatment.

摘要： Oxides (e.g., native or thermal silicon oxide) are etched from underlying silicon with a mixture of fluorine and oxygen radicals generated by a remote plasma. The oxygen radicals rapidly oxidize any uncovered bare silicon areas, preventing the pitting that can result from fluorine etching bare silicon more rapidly than it etches the surrounding oxide. A very thin (few Å), highly uniform passivation layer remaining on the silicon after the process may be left in place or removed. An oxygen-impermeable layer may be formed in-situ immediately afterward to prevent further oxidation. A pre-treatment with oxygen radicals alone fills pores and gaps in the oxide before etching begins.

摘要： Barrier layers, barrier stacks, and seed layers for small-scale interconnects (e.g., copper) are combinatorially screened using test structures sputtered or co-sputtered through apertures of varying size. Various characteristics (e.g., resistivity, crystalline morphology, surface roughness) related to conductivity, diffusion blocking, and adhesion are measured before and/or after annealing and compared to arrive at materials and process parameters for low diffusion with high conductivity through the interconnect. Example results show that some formulations of tantalum-titanium barriers may replace thicker tantalum/tantalum-nitride stacks, in some cases with a Cu—Mn seed layer between the Ta—Ti and copper.
