An input device, that includes a casing having at least an opening, a supporting base set on the casing, a base plate set within the casing, at least one pressure sensor set on the base plate, and an actuator movably set on the supporting base. The system comprises, activated by the operation of a computer, an electronic editor for simulating a display screen of a display monitor, and an interface controlling a control module associated with said display monitor. The passivated surface is not wettable by bonding material. The front-side heating source contributes to heat up the environment near the front-side of the substrate to a temperature lower than about 100\xb0 C. The resulting blast cells, which have the desired activity, are proliferated by further culture. Methods for controlling bottom stacking fault propagation in epitaxial silicon are also provided.
