The present invention relates to a method for manufacturing a Fe—Si alloy powder. A method for manufacturing a Fe—Si alloy powder includes: providing a mixture of an Al2O3 powder, an active agent powder, a Si powder, and a Fe powder; heating the mixture with a temperature of 700° C. to 1200° C. in the hydrogen atomosphere; magnetically separating a Fe-containing material from the mixture; and separating a Fe—Si alloy powder by soaking the Fe-containing material in an alkali solution. In the heating of the mixture, the Si powder is deposited on the surface of the Fe powder and diffused into the Fe powder.

Provided are a method of fabricating a porous thin film structure, by forming a thin film from at least two elements, followed by selectively removing the certain element using a dry etching process, and a porous thin film structure fabricated by the same. Because all processes of the method of fabricating a porous thin film structure are dry processes, process control is simply accomplished, environmental impact is low, and mass production is possible, in contrast to when using a typical wet process such as electrodeposition or dealloying. Also, since a level of porosity is easily controlled and maintained uniform, a mesoporous thin film structure showing a reproducible level of sensitivity when used as a sensor can be fabricated.
