摘要:
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.

A polymer resin composition, a method for forming a pattern using the polymer resin composition, and a method for fabricating a capacitor using the polymer resin composition are disclosed. The polymer resin composition includes about 75 to 93 percent by weight of a copolymer prepared from benzyl methacrylate, methacrylic acid, and hydroxyethyl methacrylate; about 1 to 7 percent by weight of a cross-linking agent; about 0.01 to 0.5 percent by weight of a thermal acid generator; about 0.01 to 1 percent by weight of a photoacid generator; about 0.00001 to 0.001 percent by weight of an organic base; and a solvent.

Disclosed is an apparatus and a method capable of processing low-speed circuit data lower than 64 kbps and high-speed packet data higher than 64 kbps in which a high-speed data network is constructed by converting an LCIN (local CDMA (code division multiple access) interconnection network) for supplying a communication path of packet data among sub-systems in a BSC (base station controller) of CDMA system to an ATM (asynchronous transfer mode) for processing high-speed data, installing a TSB (transcoder selector bank) or an SDU (selector distribution unit) for processing high-speed packet data higher than 64 kbps in the BSC, and linking an ATM switch to an MSC (mobile switching center) to provide a high-speed data service with respect to other network. The TSB for processing voice data and low-speed data lower than 64 kbps and high-speed data higher than 64 kbps, or the TSB for processing high-speed data higher than 64 kbps is provided to the BSC, thus allowing high-speed data processing up to 2 mbps, high-speed data service, multimedia service like a video service, and high-speed Internet service.

Disclosed is a variable differential mount apparatus using a Magnetorheological Elastomer (MRE). The apparatus includes a core, a coil, a plurality of MRE supports, and a magnetic path formation member. The core has a plurality of arms disposed thereon. The coil is wound on the plurality of arms, respectively. The plurality of MRE supports are disposed to face the plurality of arms, respectively. The magnetic path formation member is disposed outside the plurality of MRE supports. More specifically, a current is applied to coil to vary the degree of stiffness of the variable differential mount based on a particular driving condition to allow for increased handling and comfort.
摘要:
In a method of forming a metal or metal nitride pattern, a metal or metal nitride layer is formed on a substrate, and a photoresist pattern is formed on the metal or metal nitride layer. An over-coating composition is coated on the metal or metal nitride layer and on the photoresist pattern to form a capping layer on the photoresist pattern. The over-coating composition includes a polymer having amine groups as a side chain or a branch and a solvent. A remaining portion of the over-coating composition is removed by washing with a hydrophilic solution. The metal or metal nitride layer is partially removed using the capping layer and the photoresist pattern as an etching mask.
