Detergent Mixture Composition Preparation TRIZ Cases

Quaternary ammonium hydroxides regulate pH to solubilize contaminants, while metal inhibitors prevent copper dissolution during post-CMP cleaning.

Site-directed mutagenesis at specific residues modifies a Bacillus pumilus protease to enhance catalytic activity in washing formulations.

Optimized liquid cleaning composition removes hard masks and dry etch residues while preventing damage to low-dielectric-constant interlayer dielectric films.

Amino acid substitutions in alpha-amylase variants improve wash performance and energy efficiency by enabling effective catalysis at lower temperatures.

A solvent blend uses specific Hansen parameters to clean metal components without hazardous classifications.
