摘要:
A method of forming patterns of a semiconductor device may include forming a photoresist layer that includes a photo acid generator (PAG) and a photo base generator (PBG), generating an acid from the PAG in a first exposed portion of the photoresist layer by first-exposing the photoresist layer, and generating a base from the PBG in a second exposed portion of the photoresist layer by second-exposing a part of the first exposed portion and neutralizing the acid. The method may also include baking the photoresist layer after the first and second-exposing and deblocking the photoresist layer of the first exposed portion in which the acid is generated to form a deblocked photoresist layer, and forming a photoresist pattern by removing the deblocked photoresist layer by using a developer.

Provided is a method of forming micropatterns, in which a line-and-space pattern is formed using a positive photoresist, and a spin-on-oxide (SOX) spacer is formed on two sidewalls of the line-and-space pattern and used in etching a lower layer, thereby doubling a pattern density. Accordingly, all operations may be performed in single equipment (lithography equipment) without taking a substrate out, and thus a high throughput is obtained, and concerns about pollution are very low. Moreover, as the line-and-space pattern is formed using a wet method by using a negative tone developer, line-width roughness (LWR) of the micropatterns may be improved compared to when a dry etching method is used.

The present invention relates to a graft copolymer, a method for preparing the same and a thermoplastic resin composition comprising the same. The graft copolymer of the present invention comprises a composite rubber polymer (A-1) having an average particle diameter of 250-600 nm prepared by particle enlargement after mixing a diene rubber polymer (a-1) latex having an average particle diameter of 50-150 nm and a core-shell structured, cross-linked alkyl acrylate rubber polymer (b-1) latex having an average particle diameter of 50-250 nm. A thermoplastic resin composition prepared by mixing the graft copolymer of the present invention with a hard matrix (B) has very superior weathering resistance and superior pigmentation property, gloss, impact resistance and low-temperature impact strength.

A display apparatus and a Non-Photorealistic Rendering process (NPR) are provided. The display apparatus includes: an image processor which processes an NPR with respect to an image so that brightness of a pixel having a brightness value less than a predetermined brightness value is reduced and a brightness of a pixel having a brightness value greater than the predetermined brightness value is increased. Accordingly, a cartoon effect can be maximized.

A robot system includes a position information emitting unit including a light emitter to emit a light including phase information and a supersonic wave emitter to emit a supersonic wave, and a robot including a light receiver to receive the light, a supersonic wave receiver to receive the supersonic wave, and a position determining part to determine a relative position of the robot with respect to the position information emitting unit based on the phase information of the light received through the light receiver and the supersonic wave received through the supersonic wave receiver. Thus the robot system can precisely determine the position of the robot regardless of external environments, and reduce cost of a configuration of the system.

A video call terminal, a mobile phone and a control method thereof are provided. The video call terminal includes a first communication unit configured to conduct a video call with a second terminal through an Internet protocol (IP) network; a second communication unit configured to communicate with a mobile phone; and a controller configured to transmit first network information of the video call terminal to the mobile phone, receive second network information of the second terminal from the mobile phone, and control the video call with the second terminal using at least one of the first and second network information.
摘要:
A sketch image is generated based on a brightness of a pixel block that includes a pixel and at least one pixel surrounding the pixel. An output gray scale of the specific pixel is adjusted based on whether an input gray scale of the specific pixel is higher than the representative value. Accordingly, the display apparatus may generate a clear sketch image.
