摘要:
Provided is a method for manufacturing a printed circuit board. The method for manufacturing the printed circuit board includes applying an adhesive on a support board, attaching an electronic device on the adhesive, forming an insulation layer for burying the electronic device, separating the insulation layer from the support board, forming a lower insulation layer under the insulation layer, and forming a via connected to terminals of the electronic device in the insulation layer or the lower insulation layer. Thus, since an adhesion material of an adhesion film does not remain between the internal circuit patterns, and the internal circuit patterns are not stripped by an adhesion force of the adhesion film, device reliability may be secured.

The present invention provides an ink composition for roll printing, which comprises one or more first fluorine surfactants that comprise a hydrophilic component, a lipophilic component, and a fluorine component; and one or more second fluorine surfactants that comprise a fluorine component, and any one of a hydrophilic component and a lipophilic component.

A method for forming fine patterns includes (S1) closely contacting a cliche-forming film to a hard mold concavely patterned, thereby making a disposable cliche; (S2) coating an elastic blanket cylinder with ink or resin; (S3) compressing the elastic blanket cylinder to the disposable cliche to remove ink or resin on a surface of the elastic blanket cylinder at a portion contacting with a relatively protruded embossed portion of the disposable cliche; and (S4) transcribing ink or resin remaining on the surface of the elastic blanket cylinder to a substrate. This method allows simple and fast works and greatly reduces costs by adopting a disposable cliche that may be easily installed and removed. Also, this method may be effectively utilized to form a fine pattern of an electronic device or a display device such as color filter and electrode.
摘要:
An electric field effect transistor of high breakdown voltage and a method of manufacturing the same are disclosed. A recessed portion is formed at the channel region and is filled by a protective oxide layer. Lightly doped source/drain regions are formed under the protective oxide layer. The protective oxide layer protects the lightly doped source/drain regions. Accordingly, the protective oxide layer prevents the electric field from being concentrated to a bottom corner portion of the gate structure. In addition, the effective channel length is elongated since an electric power source is connected to heavily doped source/drain regions from an outside source of the transistor, instead of being connected to lightly doped source/drain regions.

A heat-curable ink composition and a color filter produced using the ink composition are provided. The ink composition and the color filter are highly resistant to heat and chemicals due to the use of a polyester resin prepared by polycondensation. In addition, unreacted anhydride groups are removed using a monohydric alcohol in the preparation of the ink composition to make the ink composition and the color filter very stable during storage.

An ink composition for roll printing is provided. The ink composition uses a solvent system having an evaporation rate (Vt) of at least 0.1 mg/cm2·min and an absorption rate (St) into a blanket of less than 3.412 mg/cm2·min. The use of the highly volatile solvent system can minimize swelling of the blanket without impairing the dispersibility of a pigment in the ink composition. Therefore, the uniformity of a pattern formed using the ink composition can be maintained and the formation of defects by the solvent system can be minimized.
