Abstract:
A gate electrode. The gate electrode includes a substrate, a gate dielectric layer formed thereon, and a gate conductive layer comprising a stack of polysilicon grains formed on the gate dielectric layer, wherein the average size of the polysilicon grains decreases gradually in a direction away from the substrate. The invention also provides a metal oxide semiconductor (MOS) transistor including the gate and a method of fabricating the MOS transistor.
Abstract:
A process to purify wastewater by chemical oxidation is disclosed. The purification is carried out in a fluidized bed of a suitable particulate carrier upon which the iron(III) compound produced by Fenton's reaction crystallizes or coats, thereby reducing the sludge content of effluent over 50%. In addition, the fluidized bed improves the COD removal by way of thoroughly mixing the wastewater with adding agents.
Abstract:
The present invention relates to a method for increasing the grain size of a polysilicon layer, which includes exposing a silicon oxide wafer in a deposition chamber to an amount, effective for the purpose, of nitrogen at a flow rate of at least about 240 standard liters per minute (slm). The instant invention further relates to a method for inhibiting the formation of a polysilicon seed in a furnace, which includes the treatment as noted above. The invention also relates to a method for forming a polysilicon layer, including: forming a silicon oxide layer on a substrate, the silicon oxide layer having a plurality of oxygen molecules therein; exposing the silicon oxide layer to a predetermined amount of nitrogen-containing gas in a furnace, whereby a plurality of nitrogen molecules in the nitrogen-containing gas replaces at least part of the oxygen molecules in the silicon oxide layer; and forming a polysilicon layer on the silicon oxide layer.

Abstract:
The present invention provides an initiating method for an image processing device. The image processing device includes a memory unit, a storage unit for storing multiple compressed programs therein, and a controller connected to the storage unit and the memory unit. The initiating method includes steps of: (a) selectively reading out at least one compressed program and loading the at least one compressed program into the memory unit; (b) executing a decompression program to decompress the at least one compressed program; and (c) executing the at least one compressed program which has been decompressed.
Abstract:
Disclosed is a method for treating highly concentrated wastewater by electrolysis and oxidization, said method being characterized in that the electrolysis and oxidization are carried out in a fluidized bed of a suitable particulate carrier. The electrolytic reduction efficiency of ferric ions is improved by the fluidized particulate carrier, and thus a high proportion of iron(III) to iron(II) can be sustained in the system. This invention allows extensive purification of wastewater with improved efficiency.
Abstract:
A method of treating organic compounds in groundwater utilizes permeable catalytic barriers to carry out heterogeneous catalytic oxidation to degrade organic compounds. The permeable catalytic barriers are made of highly permeable catalytic materials, used to contact with the polluted groundwater mixed with oxidant to carry out heterogeneous catalytic oxidation to degrade organic compounds. Ditches are properly excavated to be filled with catalytic materials so as to form the permeable catalytic barriers. And, groundwater monitoring wells and oxidant injection wells are also built at proper locations, so that proper amount of oxidant can be determined and re-treatment can be promptly operated if necessary.
