    摘要: Proton sponge, berberine, and cetyltrimethyl ammonium hydroxide base compounds are used as additives to chemically amplified photoresists based on modified polyhydroxystyrene (PHS). The base additives scavenge free acids from the photoresist in order to preserve the acid labile moieties on the modified PHS polymer. The base additives are well suited to industrial processing conditions, do not react with the photoacid compounds in the photoresist composition to form byproducts which would hinder photoresist performance, and extend the shelf-life of the photoresist composition. In addition, the proton sponge and berberine base additives have a different absorption spectra than the modified PHS polymer, therefore, the quantity of base additive within the photoresist can be easily assayed and controlled.

    摘要: A photo resist composition contains at least one photoacid generator (PAG), wherein at least two photoacids are produced upon exposure of the photo resist to actinic energy and wherein the photo resist is capable of producing a hybrid response. The function of providing generation of two photoacids in a hybrid resist is to optimize the use of hybrid resist by varying the hybrid space width. The at least two photoacids may differ in their effectiveness at catalyzing at least one mechanism of the hybrid response. In particular, one photoacid may be a weaker acid and another may be a stronger acid, wherein there exists a difference of at least four orders of magnitude between the acid dissociation constant (Ka) of the weaker acid and the stronger acid. A method for optimizing space width in a hybrid photo resist includes the steps of: 1) selecting a desired space width; 2) selecting at least one photoacid generator (PAG), wherein at least two photoacids will be produced upon exposure to actinic energy in relative proportions sufficient to produce the desired space width in the hybrid photo resist; and 3) forming a hybrid photo resist composition comprising the at least one PAG. The step of selecting at least one PAG may include first determining the space width produced alone by each photoacid in a group of candidate photoacids and then selecting the photoacids and corresponding at least one PAG that will produce the desired space width.
