摘要

Time dependent surface temperatures on a micro heater were measured when a voltage pulse of 25～200 μs was applied to the heater. The dimensions of the micro polysilicon heaters fabricated on a silicon substrate are 50x5x0.523 μm~3 for a micro line heater and 65X65X0.523 μm~3 for a micro square heater. With the minimum voltage needed for bubble growth, the temperature for bubble nucleation on the heater immersed in FC-72 was measured to be 420.7 K for the micro line heater, which is close to the superheat limit of the working fluid. On the other hand a bubble nucleates at temperature of 388 K on the square heater. Bubble nucleation, growth and subsequent collapse process were visualized by a microscope-35 mm camera with a us flash unit.
