Abstract:
1. A method for electrolessly depositing a layer upon a microelectronic, comprising: loading the microelectronic topography into an electroless deposition chamber; closing the electroless deposition chamber; joining a cover and a cup-shaped cover support within the electroless deposition chamber to form a sealed enclosed area about the microelectronic topography such that fluids are inhibited from leaking from the sealed enclosed area; filling the sealed enclosed area with an electroless deposition solution; electrolessly depositing a layer on the microelectronic topography from the electroless deposition solution; pressurizing the sealed enclosed area with a gas during the step of filling the sealed enclosed area with the electroless deposition solution; and heating the electroless deposition solution in the electroless deposition chamber to its boiling point and subsequently reducing the temperature of the electroless deposition solution to a working temperature range, wherein the working temperature range spans between approximately 1% and approximately 25% below the boiling point of the electroless deposition solution.
