Magnetic devices, and methods of manufacturing the same, include a stack structure including at least one magnetic layer, etched using an etching gas including at least 70 volume percent of a hydrogen-containing gas and at least 2 volume percent of CO gas.

Magnetic devices and methods of manufacturing the same

A method of forming patterns of a semiconductor device includes forming a material film on a substrate, forming a hard mask on the material film, forming a first mold mask pattern and a second mold mask pattern on the hard mask, forming a pair of first spacers to cover opposite sidewalls of the first mold mask pattern, and a pair of second spacers to cover opposite sidewalls of the second mold mask pattern, forming a first gap and a second gap to expose the hard mask by removing the first mold mask pattern and the second mold mask pattern, the first gap being formed between the pair of first spacers and the second gap being formed between the pair of second spacers, forming a mask pattern on the hard mask to cover the first gap and expose the second gap, forming an auxiliary pattern to cover the second gap, removing the mask pattern; and forming a hard mask pattern by patterning the hard mask using the first spacers, the second spacers and the auxiliary pattern as a mask.

Method of forming patterns of semiconductor device

An apparatus and method for confirming control information that is input through an earphone in a portable terminal are provided. The apparatus includes an interface to which an earphone connects, and a controller for creating bit information dependent on a key input provided from the earphone connected through the interface, and confirming control information corresponding to the bit information.

Apparatus and method for confirming control information of earphone in portable terminal

A circuit apparatus for recognizing an earphone in a mobile terminal is provided. The apparatus includes a plurality of devices, a wiring for recognizing the number of poles of the earphone, and a comparator. The plurality of devices are connected between a microphone bias power and a wiring that receives a signal from a microphone of an earphone. The wiring that recognizes the number of poles of the earphone branches from a wiring between at least two of the devices. The comparator compares a voltage of the wiring that recognizes the number of poles with a reference voltage to output a result signal.

Circuit apparatus for recognizing earphone in mobile terminal

A method of manufacturing a magnetic device includes forming a stack structure, the stack structure including a magnetic layer, and etching the stack structure by using an etching gas, the etching gas including at least 80% by volume of Hgas.
