Stripping Solution

Originally developed for the removal (stripping) of rubber-based negative resists, the use of positive resists has led to the development of strippers for both negative and positive resists.
Furthermore, in consideration of the environment, we have realized the elimination of chlorinated solvents and the implementation of non-phenol, and offer a variety of stripping solutions for each resist.
We have also commercialized stripping solutions that specialize in removing deposited or altered membranes after ashing or dry etching, and stripper solutions that take into account metal damage on devices.

Stripping Solution 502A

Stripping solution 502A is a stripper for negative and positive photoresists that does not contain chlorinated solvents, which have become a problem in recent years due to environmental pollution. We have also commercialized Clean Strip HP-2, which does not contain phenol.

Stripping Solution for Deposited Materials SST-A2

As patterns become smaller and finer, it becomes more difficult to remove deposited materials after dry etching, and a more powerful stripping solution is required.
SST-A2 is a water-soluble stripping solution for deposited materials after dry etching of Al-Si, Tin/Al-Si-Cu/TiN, Al-Si-Cu/TiN, Al-Si-Cu/TiN interconnects, SiO2/TiN/Al-Si-Cu, and SiO2/TiN/Al-Si holes at room temperature in a short time without damage to the metal.

ST-120

ST-120 is a stripping solution for thick film resists. It allows for water rinsing and low metal damage.
