摘要:
Disclosed herein is a method for manufacturing a printed circuit board, the method including: preparing a base substrate having a connection pad; forming a surface treatment layer on the connection pad; refrigeration-treating the base substrate having the connection pad on which the surface treatment layer is formed; and printing a solder paste on the connection pad of the refrigeration-treated base substrate.

The inventive chimeric ligand in the form of a fusion polypeptide of a single-chain antibody specific for Tag-72 surface antigen and GaLV envelope glycoprotein shows high transduction efficiency to cancer cells, specifically infects target cells and efficiently delivers a therapeutic gene. Accordingly, the inventive chimeric ligand can be effectively used for gene therapy to inhibit tumor growth and metastasis.
摘要:
A method of producing a polymer capacitor includes forming a first electrode on a surface of a first ion exchange resin solid and coating a mixture of an ion exchange resin solution and a salt on the other surface of the first resin; putting a second ion exchange resin solid which has a second electrode formed on a surface thereof on the coated layer and conducting lamination of the resulting structure to produce a composite; dissolving the salt to form pores; and filling the pores with an electrolytic solution.
摘要:
An antenna structure for an inductively coupled plasma generator suitable for processing large-diameter wafers or large, flat-panel display devices by making a plasma density distribution uniform and symmetrical with respect to a rotating direction inside a circular or rectangular chamber in which a wafer is processed. In the antenna structure having a powered end to which RF power is applied and a ground end connected to the ground, at least two loop antenna elements are disposed electrically in parallel with each other, the powered ends and ground ends of the respective antennas are disposed symmetrically with respect to the center of the antennas, and the antennas crossing each other such that the powered ends and ground ends thereof are disposed at a part far from a chamber and central parts thereof are disposed at a part close to the chamber.
