The difference in heat dissipation has a significant impact on the cooling rate, in particular, when long annealing or high intermediate (preheat) temperature is used. These produce higher performing devices with improved drive currents and/or lower leakage currents, and provide design engineers more opportunities for product . FIGURE 3 shows different LSA annealing temperature-time (T-t) regimes that can be used to meet various application needs. A devices thermal budget is a time/temperature calculation. Hence a single laser spike annealed trace provides a cross section of the thermal history of the annealing process. Similar to the laser spike annealing system, the LM7 is also based on two laser sources, but provides annealing on a much shorter, nanosecond scale - meaning far less heat is transferred. There are two main approaches to annealing; one is the traditional lamp-based approach, and the other is LSA, a more advanced option.
