摘要:
In a clean room, after conducting a surface treatment on the surface of a semiconductor substrate with 4-trimethylsiloxy-3-penten-2-one, the treated surface of the semiconductor substrate is coated with a chemically amplified resist, thereby forming a first resist film. Then, the first resist film is successively subjected to exposure, PEB and development, thereby forming a first resist pattern of the chemically amplified resist. Next, in the same clean room, after conducting a surface treatment on the surface of the semiconductor substrate with 4-dimethyl-n-hexylsiloxy-3-penten-2-one, the treated surface of the semiconductor substrate is coated with a non-chemically amplified resist, thereby forming a second resist film. Then, the second resist film is successively subjected to the exposure, the PEB and the development, thereby forming a second resist pattern of the non-chemically amplified resist.
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(CH 3 ) 3 (trimethylsilyl group) is substituted for the hydrogen atom of an OH group on the surface of the semiconductor substrate, resulting in (CH 3 ) 2 CO (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:
Within a coater not provided with a chemical filter, 4-trimethylsiloxy-3-penten-2-one is supplied as a surface treatment agent onto the surface of a semiconductor substrate of silicon, thereby making the surface of the semiconductor substrate hydrophobic so as to improve the adhesion of the semiconductor substrate. Then, within the coater, the semiconductor substrate is coated with a chemically amplified resist, thereby forming a resist film. Subsequently, the resist film is exposed by using a desired mask within an exposure machine not provided with a chemical filter. Ultimately, the exposed resist film is successively subjected to PEB and development within a developer not provided with a chemical filter, thereby forming a resist pattern.
摘要:
A surface of a semiconductor substrate of silicon is supplied with 4-trimethylsiloxy-3-penten-2-one serving as a surface treatment agent. Thus, H in OH groups existing on the surface of the semiconductor substrate is substituted with Si(CH 3 ) 3 (i.e., a trimethylsilyl group), resulting in producing CH 3 COCH 2 COCH 3 (i.e., acetylacetone). Then, the surface of the semiconductor substrate is coated with a resist, exposed by using a desired mask, and subjected successively to PEB and development, thereby forming a resist pattern thereon. Since the surface of the semiconductor substrate is treated with 4-trimethylsiloxy-3-penten-2-one, the surface of the semiconductor substrate is made to be hydrophobic, so that the adhesion of the semiconductor substrate can be improved. As a result, the resultant resist pattern has a satisfactory shape free from peeling.
