Abstract

A photosensitive-resin remover composition includes an amine compound and de-ionized water, an amount of the de-ionized water being about 45% to about 99% by weight based on a total weight of the composition.

Claims (17)

1. A photosensitive-resin remover composition, consisting essentially of:

an amine compound selected from hydrazine hydrate, methyl amine and diethyl amine;

a removing accelerator in an amount of about 0.01% to about 10% by weight based on a total weight of the composition, wherein the removing accelerator is selected from methyl gallate, 1,2,3-benzenetriol and 1,3,5-benzenetriol; and

de-ionized water, an amount of the de-ionized water being about 45% to about 99% by weight based on a total weight of the composition,

wherein the photosensitive-resin remover composition has a viscosity of about 1 to about 2 centipoise.

2. The photosensitive-resin remover composition consisting essentially of:

an amine compound selected from hydrazine hydrate, methyl amine and diethyl amine;

a removing accelerator in an amount of about 0.01% to about 10% by weight based on a total weight of the composition, wherein the removing accelerator is selected from methyl gallate, 1,2,3-benzenetriol and 1,3,5-benzenetriol;

de-ionized water, an amount of the de-ionized water being about 45% to about 99% by weight based on a total weight of the composition,

a corrosion inhibitor, the corrosion inhibitor including at least one of an aromatic mercapto compound, a triazole compound, an ammonium salt, and/or a polysaccharide,

wherein the photosensitive-resin remover composition has a viscosity of about 1 to about 2 centipoises.

3. A photosensitive-resin remover composition, consisting essentially of:

hydrazine hydrate in an amount of about 1% to about 3% by weight;

a removing accelerator in an amount of about 1% to about 3% by weight, based on a total weight of the composition, wherein the removing accelerator is selected from methyl gallate, 1,2,3-benzenetriol and 1,3,5-benzenetriol;

butyl diglycol in an amount of about 10% to about 40% by weight; and

de-ionized water in an amount of about 70% to about 88% by weight,

wherein the photosensitive-resin remover composition has a viscosity of about 1 to about 2 centipoises.
