An improved photolithography technique is provided whereby the beneficial effects of using an anti-reflective coating may be realized while maintaining critical dimensions in each subsequent step. Thus, the controller can ensure good followability to a target value of the feedback control even when the automatic transmission fluid temperature is low. This is energized by the liner collapse and jetting process such that on impact and interaction with a snowice target it gererates a directed blast effect extending beyond that achievable with a simple blast charge of the same mass.
