A method for optimizing a code sequence by tuning the representations of an instruction set based on the frequency of operations performed by the code sequence. Thus, a further object is the use of this new composition in a process for the etching of surfaces semiconductor devices or surfaces of solar cell devices. 0\xd710\u22124\u2003\u2003where W is the compounding ratio wt % of a urethane acrylate compound contained in the resin composition, N is the number of urethane groups in one molecule of the urethane acrylate compound, and MW is the average molecular weight of the urethane acrylate compound.
