摘要: To the surface of a semiconductor substrate made of silicon, isopropenoxytrimethylsilane is supplied as a surface treating agent to render the surface of the semiconductor substrate hydrophobic and increase adhesion to the semiconductor substrate. Thus, Si(CH3)3 (trimethylsilyl group) is substituted for the hydrogen atom of an OH group on the surface of the semiconductor substrate, resulting in (CH3)2CO (acetone). Subsequently, a chemically amplified resist is applied to the surface of the semiconductor substrate and exposed to light by using a desired mask, followed sequentially by PEB and development for forming a pattern. Since the surface treating agent does not generate ammonia, there can be formed a pattern in excellent configuration with no insoluble skin layer formed thereon.

摘要: A BPSG film is formed on a semiconductor substrate and caused to reflow under an atmosphere of flowing Ar gas. Then, a chemically amplified resist is applied to the surface of the BPSG film to form a resist film, which is exposed to the irradiation of a KrF excimer laser through a mask. Since no lone pair of electrons exists on the surface of the BPSG film, an acid in the resist film is not deactivated and hence a reaction is evenly induced by an acid catalyst. After the development of the resist film, a resist pattern having an excellent profile with no footing is obtained.

摘要: After forming a TiN film on a semiconductor substrate, a surface treatment agent in a gas phase, which is obtained by bubbling trimethylsilyl methylsulfonate with a nitrogen gas, is supplied onto the TiN film. The TiN film is then coated with a chemically amplified positive resist including an acid generator and a compound which can attain alkali solubility through the function of an acid, and a pre-bake process is subsequently conducted, thereby forming a resist film. The resist film is then exposed with a KrF excimer laser by using a desired mask. Through this exposure, an acid is generated from the acid generator included in the resist film. Since sulfonic acid produced from trimethylsilyl methylsulfonate weakens the function as a base of a nitrogen atom having a lone pair, the acid generated from the acid generator is not deactivated at the bottom of the resist film. As a result, a resist pattern with a satisfactory shape free from footing can be formed.

摘要: The composition of a resist material is determined so that the film thinning quantity of the resist pattern is increased when the profile of a resist pattern which is formed in advance tends to be a T-top profile as compared with a reference pattern profile but so that the film thinning quantity of the resist pattern is decreased when the profile of the resist pattern which is formed in advance tends to be a round-shoulder profile as compared with the reference pattern profile. After coating a semiconductor substrate at its top with the resist material whose composition is determined as such to thereby form a resist film, the resist film is exposed through a mask. The exposed resist film is developed, whereby a resist pattern is obtained.
