Abstract:
Provided may be a slurry composition for chemical mechanical polishing (CMP) and a CMP method using the same. For example, the slurry composition may include a first polishing inhibitor including at least one of PO43− or HPO42− and a second polishing inhibitor, which may be a C2-C10 hydrocarbon compound having —SO3H or —OSO3H. By using the slurry composition for CMP and a CMP method using the same, increased selectivity to SiN may be obtained.
Abstract:
A semiconductor memory device checks a RAS timing to recognize and set an operation timing of the semiconductor memory device. The semiconductor memory device includes an input buffer, a RAS timing controller and a bank controller. The input buffer transmits a RAS timing test signal. The RAS timing controller generates a RAS timing signal. The bank controller controls a refresh operation timing in response to an output of the input buffer in a test mode and the RAS timing signal in a normal mode.

In one embodiment of the present disclosure a method for forming a PEM fuel cell electrode is provided. The method includes applying a hydrophilic wetting agent on an electrode surface. A catalyst layer is deposited on the wetted electrode surface by pulse electrodeposition, at least a portion of the catalyst penetrating the electrode surface. The electrode surface is heat treated.
Abstract:
A refresh control circuit and method thereof and a bank address signal change circuit and methods thereof. The bank address signal change circuit may receive bank address signals from a bank address signal generation circuit. The received bank address signals may designate a first at least one of a plurality of memory banks. The bank address signal change circuit may determine whether the first at least one designated memory bank is associated with the longest refresh cycles from among the plurality of memory banks. Based on the determination, the bank address signal change circuit may generate a plurality of bank address signal change signals designating a second at least one of the plurality of memory banks. A refresh operation circuit may perform a refreshing operation on the second at least one memory banks in accordance with the bank address signal change signals. The bank address signal generation circuit, bank address signal change circuit and refresh operation circuit may each be included in a refresh control circuit.
Abstract:
A process for synthesis of a catalyst is provided. The process includes providing a carbon precursor material, oxidizing the carbon precursor material whereby an oxygen functional group is introduced into the carbon precursor material, and adding a nitrogen functional group into the oxidized carbon precursor material.
Abstract:
The present invention relates to a composition comprising extracts of Gramineae plant that improves cell viability under hypoxic conditions by inhibiting apoptosis. Thus, the extract of Triticum aestivum L., one of the Gramineae plant, of the present invention, in particular, prevents damage of brain, heart and kidney in animal models of ischemic diseases, and it also improves memory in an animal model of Alzheimer's disease. Therefore, a composition comprising extracts of Gramineae can be used as therapeutic agents or health care foods for preventing and treating ischemic diseases and degenerative brain diseases.

The wordline enable circuit includes a wordline control signal generating unit for outputting an untoggled wordline control signal while a unit wordline block is enabled in a self-refresh mode; a wordline enable signal generating unit for generating a wordline enable control signal, controlled by the untoggled wordline control signal and a toggled address signal, and a first to an n-th wordline enable power supply signals; and a wordline block enable unit for enabling each wordline, controlled by the wordline enable control signal and the first to the n-th wordline enable power supply signals.
Abstract:
A slurry composition useful for chemical mechanical polishing of the surface of a material layer, e.g., a silicon oxide layer, is disclosed. A first material surface which is exposed to the slurry exhibits hydrophilicity, while a second material layer, e.g., a polysilicon layer, the surface of which is also exposed to the slurry, exhibits hydrophobicity, and accordingly acts as a polishing stopping layer. The slurry composition consists essentially of water, abrasive grains, and a polymer additive having both hydrophilic and hydrophobic functional groups.
