摘要:
A semiconductor device having a deep contact structure having an improved contact resistance is presented. The semiconductor device includes a semiconductor substrate, a first interlayer insulating layer, a contact plug, a second interlayer insulating layer, and a copper contact pad. The contact plug is formed in the first interlayer insulating layer and has a bulbous shaped upper side wall and an inwardly tapered lower side wall that extends downward towards the semiconductor substrate. The second interlayer insulating layer is formed over first interlayer insulating layer such that the second interlayer insulating layer includes a hole that exposes a top surface and a peripheral portion of the bulbous shaped upper side wall of the contact plug. The copper contact pad is buried within the hole so that the exposed parts of the bulbous shaped upper side wall of the contact plug protrude into the copper contact pad.

摘要:
An apparatus and method for tuning the volume of a sound downloaded from an outside source in a device for outputting such a sound through a speaker are provided. The apparatus includes a memory, a speaker, a microphone, a codec, a volume tuning determining unit, and a volume tuner. The memory stores a sound signal downloaded from the outside source. The speaker outputs the sound signal stored in the memory. The microphone receives the sound signal output from the speaker. The codec outputs modulation data of the sound signal input from the microphone. The volume tuning determining unit calculates volume figure data with respect to the sound signal, stress figure data of the speaker, and volume adjustment gain data using the modulation data. The volume tuner tunes the volume of the sound signal using the calculated volume adjustment gain data.

A method and apparatus for providing a user input back channel (UIBC) in an audio/video (AV) source device and an AV sink device communicating according to a wireless fidelity (Wi-Fi) display (WFD) standard is provided. The method includes: setting up an AV control session and an AV data session between the AV source devices according to the WFD standards; enabling the UIBC from the AV sink device to the AV source device by using the AV control session; and transmitting a user input from the AV sink device to the AV source device through the UIBC.
摘要:
Disclosed is a liquid formulation of long-acting human growth hormone (hGH) conjugate, free of albumin, which can guarantee the stability of the long-acting hGH conjugate when stored over a long period of time, wherein the long-acting human growth hormone conjugate includes a human growth hormone linked to an immunoglobulin Fc region, and has a prolonged in vivo stability compared to the native form. The liquid formulation of hGH conjugate including a pH 5.0˜6.0 buffer, a sugar alcohol, a salt and a non-ionic surfactant is free of human serum albumin and other hazardous factors which are potentially contaminated with viruses, and can provide excellent storage stability customized for a long-acting hGH conjugate composed of an hGH polypeptide and an immunoglobulin Fc region which has higher molecular weight and in vivo durability, compared to the native.
