    Abstract: Described herein is a method of removing an organic-containing material from an exposed surface of a large substrate (at least 0.25 m2). The substrate may comprise an electronic device. The exposed surface is treated with a stripping solution comprising ozone (O3) in a solvent, where the solvent comprises acetic anhydride. The stripping solvent used to form the stripping solution may comprise a mixture of acetic anhydride with a co-solvent selected from the group consisting of a carbonate containing 2-4 carbon atoms, ethylene glycol diacetate, and combinations thereof. In some instances, the stripping solution may contain only acetic anhydride and ozone, where the ozone concentration is typically about 300 ppm or greater.

    Abstract: Described herein are methods of forming a thin silicon dioxide layer having a thickness of less than eight angstroms on a semiconductor substrate to form the bottom layer of a gate dielectric. A silicon dioxide layer having a thickness of less than eight angstroms may be formed by two different methods. In one method, a sulfuric acid solution is applied to a semiconductor substrate to grow a silicon dioxide layer of less than eight angstroms. The growth of the silicon dioxide layer by the sulfuric acid solution is self-limiting. In another method, a hydrogen peroxide containing solution is applied to a semiconductor substrate for a time sufficient to grow a silicon dioxide layer having a thickness of greater than eight angstroms and then applying an etching solution to etch the silicon dioxide layer down to a thickness of less than eight angstroms.

    Abstract: Methods of preventing air-liquid interfaces on the surface of a wafer in order to prevent the formation of particle defects on a wafer are presented. The air-liquid interfaces may be prevented by covering the entire surface of the wafer with liquid at all times during a cleaning process while the surface of the wafer is hydrophobic. Methods of preventing the formation of silica agglomerates in a liquid during a pH transition from an alkaline pH to a neutral pH are also presented, including minimizing the turbulence in the liquid solution and reducing the temperature of the liquid solution during the transition.

    Abstract: Embodiments of the current invention describe ammonia hydroxide treatments for surfaces. In one embodiment, a method and a cleaning solution including ammonium hydroxide (NH4OH), water (H2O), a chelating agent, and a surfactant for cleaning silicon germanium substrates are described. The cleaning solution does not include hydrogen peroxide (H2O2) because hydrogen peroxide etches germanium. In another embodiment, a method of terminating oxidized surfaces on semiconductor substrates with terminating groups that promote the bonding of the oxidized surface to another surface with a surface treatment containing ammonium hydroxide (NH4OH) is described. The oxidized surface is immediately bonded to a second substrate after evaporation of the surface treatment.

    Abstract: According to one aspect of the present invention, a method and apparatus for cleaning a semiconductor substrate are provided. The apparatus may include a chamber wall defining a processing chamber having a chamber gas therein, a semiconductor substrate support, and a fluid nozzle within the processing chamber having first and second pieces. The first piece may have a tip with a tip opening, and the second piece may have inlet and outlet openings and a fluid passageway therethrough interconnecting the inlet and outlet openings. A space may be defined in the fluid nozzle such that when a semiconductor substrate processing fluid is directed into the fluid passageway a relative low pressure region being formed within the fluid passageway to draw the chamber gas into the fluid passageway through the space between in the fluid nozzle, mix with semiconductor substrate processing fluid, and flow onto the semiconductor substrate.
