Abstract:
PURPOSE: A method for forming a porous material layer of a semiconductor device is provided to be capable of originally preventing the generation of carbon residues and generating porosities in an impurity containing inorganic material layer. CONSTITUTION: A predetermined material layer is formed on a substrate(31). At this time, the predetermined material layer contains predetermined impurities to react with H2O molecules. A plurality of porosities are generated in the predetermined material layer by heating the resultant structure using vapor under a high pressure(37). Preferably, an insulating layer is used as the predetermined material layer. Preferably, the insulating layer is made of one selected from a group consisting of the first BPSG layer, the first BSG layer, the second BPSG containing PSG and fluorine atoms, or the second BSG layer containing fluorine atoms. Preferably, the predetermined impurities are boron atoms or phosphor atoms.

PURPOSE: A method for forming a pattern of an intermetal dielectric layer is provided to be capable of preventing the generation of photoresist residuals after carrying out a developing process by changing the chemical structure of the surface of a via hole using UV(UltraViolet) ray. CONSTITUTION: After sequentially forming a lower etching stop layer(2), a lower insulating layer(3), an upper etching stop layer(4), and an upper insulating layer(5) at the upper portion of a lower line(1) formed semiconductor substrate, a via hole is formed by selectively patterning the upper insulating layer, the upper etching stop layer, and the lower insulating layer for exposing the lower etching stop layer. Then, UV ray is irradiated to the via hole. After forming a photoresist layer(8) on the entire surface of the resultant structure, a photoresist pattern is formed by selectively patterning the photoresist layer.

PURPOSE: A method for forming a metal film of a semiconductor device is provided to prevent cross talk when a signal is transferred among electrically isolated metal lines by forming a low dielectric insulation layer. CONSTITUTION: A first metal pattern(42) and a first insulation layer(44) are sequentially formed on a substrate(40). A second insulation layer(46) having a low dielectric constant is formed. Ultraviolet ray is irradiated on the entire surface of the resultant structure. A via hole(52) is formed by patterning the resultant structure to expose the first metal pattern(42). A second metal pattern(56) is formed to be connect to the first metal pattern(42) through the via hole(52). The second insulation layer(46) is able to be formed by using SiOC layer. The ultraviolet ray make the layer(46) strong about oxygen plasma.
