| 20080293253 | Wet etching of the edge and bevel of a silicon wafer - An apparatus and method used to selectively etch materials from the edge and bevel areas of a silicon wafer are provided. In one configuration, a bevel etch spin chuck, for use in a device for removing unwanted material from an edge and bevel area of a wafer, includes a fluid channel, a separation barrier, and a gas channel that are substantially circular and concentric. A fluid, such as an etching solution, is provided to the fluid channel and contacts one or more areas at the edge and bevel area of the wafer. A stream of continuously flowing gas, such as nitrogen, is provided to the gas channel and purges an active side of the wafer. | 11-27-2008 |

| 20080202556 | One-Handed Method of Cleaning Surfaces - A pump dispenser has a large ergonomic actuator designed to ergonomically deliver a composition to a substrate in the consumer's hand without the consumer having to pick up the pump dispenser. The ergonomic design allows the composition to be delivered in a proper aspect ratio to the substrate. The composition can be delivered in such a way that the composition is not aerosolized into the air or delivered to an unintended surface. The method of delivery can be made intuitive to the consumer by providing an actuator skirt that suggests the pumping mechanism or by providing a depiction of a hand or substrate over the pump dispenser. The pump dispenser is also useful for compositions or substrates that are not stable together. | 08-28-2008 |
| 20080245821 | Pump Dispenser for Use with Thickened Liquids and Substrates - A vertical pump-up dispenser dispenses a fluid composition having a critical rheology that together with the dispenser delivers sufficient flow with a consumer preferred pressure drop and viscosity. The dispenser may also be designed to generate a foaming product. | 10-09-2008 |
| 20080273915 | Sensory Cue For Pump Dispenser For Use With Substrates - A vertical pump-up dispenser contains sensory cues on the actuator top which conveys consumer information, such “as what the product is” or “how to use the product” or “what brand the product is” or what fragrance the product is“. The sensory cue may be one or more colors, shapes, graphics, text, alpha-numeric characters, and/or patterns. The sensory cue may include both a visual cue and a tactile cue. | 11-06-2008 |

| 20080264827 | Retail Display for Pump Dispenser for Use With Substrates - A retail or advertising display contains visual cues which convey the area of use and the method of use of a novel vertical pump-up dispenser to the consumer. Having a sponge or other substrate on top of the dispenser conveys the area of use of the dispenser. The dispenser has a large actuator surface designed to convey that it can deliver a composition to a broad substrate area, such as a sponge, in the consumer's hand without the consumer having to pick up the pump dispenser. Having a hand over the substrate and dispenser conveys the one-handed method of cleaning that the dispenser allows. There may be additional indicia of use, such as arrows pointing down. The retail display may contain the dispenser and the substrate packaged together. | 10-30-2008 |
