A semiconductor structure and method for forming the same. A pressure booster that has a movable piston is connected between the at least one injector and a high-pressure working medium source. 5 to 8, and a second polymer component having a molecular weight distribution of from 1. The plunger assembly includes a shaft on which a cap is slidably and rotatably mounted. As a result, the durability of the pulleys and V-shaped blocks can be improved. Other embodiments are disclosed.
