  • Patent number: 10894935
    Abstract: Compositions for removing silicone resins and methods of thinning a substrate by using the same, as well as related methods, apparatus and systems for facilitating the removal of silicone resins are provided. The compositions for removing silicone resins, may include a heterocyclic solvent and an alkyl ammonium fluoride salt represented by a formula, (R)4N+F?, wherein R is a C1 to C4 linear alkyl group. Silicone resins may be effectively removed by using the compositions since the compositions exhibit an excellent decomposition rate with respect to the silicone resins that remain on a semiconductor substrate in a process of backside grinding of the semiconductor substrate, backside electrode formation, or the like.
