Method of forming carbon polymer film using plasma CVD

A method of forming a hydrocarbon-containing polymer film on a semiconductor substrate by a capacitively-coupled plasma CVD apparatus. The method includes the steps of: vaporizing a hydrocarbon-containing liquid monomer (CαHβXγ, wherein α and β are natural numbers of 5 or more; γ is an integer including zero; X is O, N or F) having a boiling point of about 20° C. to about 350° C. which is not substituted by a vinyl group or an acetylene group; introducing the vaporized gas and CO2 gas or H2 gas into a CVD reaction chamber inside which a substrate is placed; and forming a hydrocarbon-containing polymer film on the substrate by plasma polymerization of the gas, thereby reducing extinction coefficient (k) at 193 nm and increasing mechanical hardness.

Apparatus and method for production of three-dimensional models by spatial light modulator

An apparatus and the method of its operation for rapid prototyping of a three-dimensional object which includes a radiant energy source of a wide beam of radiant energy of suitable intensity and wavelength for curing a layer of photo-curable resin contained in an open vat, a spatial light modulator (SLM) having an array of pixel elements which are individually digitally controllable by a computer, for modulating the radiant energy beam projected from the radiant energy source on a pixel by pixel basis, to form a series of time sequential images of the cross-sectional laminae of the object, an optical system for focusing each image formed by the SLM, one at a time, onto successive layers of photo-curable resin for predetermined exposure times to thereby form stacked laminae of cured resin, each lamina of cured resin being in the shape of a different one of the cross-sectional laminae, and a piston support for lowering each lamina of cured resin after it is formed by the SLM and for depositing a layer of resin corresponding to the thickness of one cross sectional lamina of the three-dimensional object before the step of projecting a new image by the SLM. The SLM, the piston support for lowering, and the optical system operate repeatedly and sequentially until a complete copy of the object is thereby produced.

General electronic paste based on graphene filler

The invention discloses general electronic paste based on graphene filler. The electronic paste contains graphene-containing conductive filler, an organic carrier, a solvent and an auxiliary agent. Because the graphene has good electronic conductivity and a unique two-dimensional laminar nano structure, the graphene forms a conductive network in the organic carrier more easily, and the electric conductivity of the electronic paste is improved by adding the graphene. Further, the conductive filler also contains a conductive material with relatively high electric conductivity, so that the electric conductivity of the electronic paste is further improved. Because the graphene and the conductive material are compounded to form the conductive filler, the electronic paste has good electric conductivity. The electronic paste can obtain a relatively wide electric conductivity range by changing the category of the conductive material mixed with the graphene and adjusting the relative proportion of the graphene to the conductive material of different category. The electric conductivity of the electronic paste is 1*10<-3>S / cm to 1*10<3>S / cm. The paste can be widely applied, and can be particularly used as a conductive coating or adhesive.
