    摘要: Non-aqueous cleaning compositions capable of removing cured polyimides and other polymers from a metal circuitry containing substrate such as a semiconductor device for rework and other purposes without any significant adverse affect on the circuitry are provided consisting essentially of alkanolamines, preferably monoethanolamine or monoethanolamine-diethanolamine mixtures and optionally with a solvent such as NMP in an amount less than about 50% by weight. A method is also provided for removing polyimide coatings and other polymers from semiconductor devices using the cleaning compositions of the invention.

    摘要: Methods and compositions for the selective etching of silicon in the presence of p-doped silicon are disclosed whereby a portion of a silicon surface may be dissolved while a p-doped pattern in the surface remains substantially undissolved. The compositions comprise (a) an aqueous solution of an alkali metal hydroxide or a tetraalkylammonium hydroxide; and (b) a high flash point alcohol, phenol, polymeric alcohol, or polymeric phenol.

    摘要: A process is disclosed for making circuit elements by photolithography comprising depositing an antireflective polyimide or polyimide precursor layer on a substrate and heating the substrate at 200.degree. C. to 500.degree. to provide a functional integrated circuit element that includes an antireflective polyimide layer. The antireflective polyimide layer contains a sufficient concentration of at least one chromophore to give rise to an absorbance sufficient to attenuate actinic radiation at 405 or 436 nm. Preferred chromophores include those arising from perylenes, naphthalenes and anthraquinones. The chromophore may reside in a dye which is a component of the polyimide coating mixture or it may reside in a residue which is incorporated into the polyimide itself.
