address line 304 may be used to select a particular row and the signal line 306 may be used to select a particular column within an array of micro thrusters cells referring specifically to fig5 when the signal line 306 and the address line 304 are both high transistor 305 is activated pulling the gate of drive transistor 307 high this turns on drive transistor 307 which pulls current though emitter resistor 302 this current heats the emitter resistor causing the explosive igniter to explode as described above referring now to fig6 microthruster device 200 of fig4 is illustrated in an exploded perspective view the illustrative microthruster device 200 is formed upon substrate wafer 28 a silicon dioxide layer is grown on the substrate wafer 28 cavities 122 are then etched into the silicon dioxide layer to form first cavity walls 26 explosive igniter 132 is preferably suspended above the floor of the first cavities 122 and may have a serpentine form as previously described signal line 306 and pixel address line 304 may be used to active the explosive igniter 132 as previously described in fig5 explosive igniter 132 is preferably formed of a serpentine shaped resistor that is encapsulated in a sheet of silicon nitride the combined resistor and.
