Technical field
The present invention relates to hard mask compositions, particularly relate to the organosilane hard mask compositions that is used for the resist underlying membrane.The invention still further relates to and adopt the organosilane hard mask compositions to make the method for semiconductor devices.
Background technology
In photoetching process,, antireflecting coating (ARC) material can be used for minimize such as the imaging layer of photoresists layer and the reflectivity between the substrate in order to obtain better resolution., because resist layer has the composition similar to the ARC material usually, therefore, with respect to imaging layer, this ARC material can provide very poor etching selectivity.Therefore, owing to when forming figure after etching ARC material, can remove most of imaging layer, therefore in etching step subsequently, can require to form additional patterns.
, in some optical patterning methods, anticorrosive additive material can not provide enough elching resistants, is delivered to layer below the anticorrosive additive material effectively with the figure with needs.In the application of reality, the so-called hard mask that is used for the resist lower membrane can be as the middle layer between the substrate of the resist of patterning and desirable patternization.For example, when use the ultrathin membrane anticorrosive additive material, want etched substrate very thick, when needing basic etch depth and/or needing to use special etchant to be used for particular substrate, just need be used for the hard mask of resist lower floor.The hard mask that is used for the resist lower membrane can be accepted figure from the resist layer of patterning, and this figure is passed to substrate.The hard mask that is used for the resist lower membrane should be able to stand figure need be passed to the etching process of following material.
For example, when processing such as the substrate of silicon, can be with the resist figure as mask.At this moment, resist can be had the thickness of reduction by miniature imageization.Therefore, because the mask character deficiency of resist, so the trade union that adds of substrate produces damage to substrate.Therefore, the lower membrane that can adopt a kind of method that resist pattern is at first passed to be used to process substrate (for example hard mask) is then used lower membrane to do as mask and is carved substrate.The lower membrane that is used to process substrate refers to the film that can form and can play the anti-reflecting layer effect below anti-reflective film.In this process, the rate of etch of resist can be close with the rate of etch of the lower membrane that is used to process substrate.Therefore, may need to form hard mask, be used to process the lower membrane between resist and the lower membrane, described hard mask also can be antireflecting.As a result, can in substrate, form by the lower membrane that is used to process substrate, be used to process the hard mask of lower membrane and the multilayer film that resist is formed.
Investigated multiple hard mask material.For example Japanese unexamined publication No.2000-0077018 has described at resist lower membrane formula of RaSi (OR)
4-aThe purposes of polycondensation products of silane compound.A problem relevant with using this polycondensation products is that unreacted raw material and/or the low-molecular-weight secondary product that obtains can produce bad influence and cause the graphics performance variation the resist layer on the hard mask layer when polycondensation.
Therefore, wish identification hard mask compositions and use said composition to make unreacted raw material or the minimized method of low-molecular-weight secondary product in the hard mask layer of formation.
