Abstract: A method of removing copper oxide from copper surfaces is disclosed that comprises application of vapor generated by an ultrasonic wave nebulizer. The energized vapor droplets include water and a weak organic acid such as acetic acid, lactic acid, citric acid, uric acid, oxalic acid, or formic acid that have a vapor pressure proximate to that of water. The weak organic acid preferably has a pKa high enough to avoid Cu etching but is sufficiently acidic to remove copper oxide at a rate that is compatible with high throughput manufacturing. In one embodiment, weak acid/water vapor is applied to a substrate in a spin bowl and is followed by a deionized water rinse step in the same spin bowl. Improved wettability results in improved uniformity in subsequently plated copper films. Considerable cost savings is realized as a result of reduced chemical consumption and higher product yields.

Abstract: A method includes activating a transistor providing current to a load via an inductor based on values stored at a first timer and at a second timer. The second timer is enabled based a value of a current conducted at the inductor and based on a value of a reference current. The transistor is deactivated in response to determining that a measurement of time elapsed at the first timer is a predetermined multiple of the second measurement of time.

Abstract: A display device comprises a cover and a display module. The cover includes a bottom plate and at least one cover limit element. The cover limit element projects inwardly from an inner surface of the bottom of the cover. A space is formed between the bottom plate and the cover limit element. The display module includes a frame with at least one frame limit element disposed at an end of the frame and projecting at a position between the cover limit element and the bottom plate. The frame limit element is configured to be disposed in the space and between the cover limit element and the bottom plate to retain the display module with the cover.

Abstract: Polymers including ?-hydroxymethylacrylate units and methods of preparing polymers from ?-hydroxymethylacrylates are provided. Advantageously, ?-hydroxymethylacrylates may be used in an emulsion polymerization and function as a polymerizable surfactant. The ability of the ?-hydroxymethylacrylates to be used as a polymerizable surfactant allows for emulsion polymerization systems to be prepared without other surfactants.

The fan is located in the accommodating space and keeps a distance from the casing. Each of the two vibration absorption assemblies includes two first vibration absorption components and a second vibration absorption component. The two first vibration absorption components are respectively in contact with the fan and separated from the casing, respectively. The second vibration absorption component is connected with two first vibration absorption components and the casing, respectively. The first vibration absorption components and the second vibration absorption components are adapted for absorbing the vibration waves having different frequency ranges.

Abstract: A method of preparing a polymer is provided comprising preparing a Baylis-Hillman adduct by reacting an activated alkene with a carbon electrophile; and polymerizing the Baylis-Hillman adduct. The Baylis-Hillman reaction provides an efficient platform for the synthesis of densely functionalized monomers, from which polymers with multiple functional groups can be readily synthesized. It has been discovered that that Baylis-Hillman adducts are versatile monomers for both controlled radical and step-growth polymerizations.
