The most important feature of microwave annealing for semiconductor wafers is that they can complete annealing at lower temperature. This low thermal budge annealing process is a great advantage for semiconductor manufacturing. Semiconductors are manufactured in front-end, back-end, or packaging processes, and their dopant activation, defect repair, or polymer curing require thermal annealing for anality modification. However, with the evolution of Moore's Law, in order to avoid dopant diffusion or damaging material structure, the allowable temperature for annealing is getting lower and lower than in the past. The component bonding of the semiconductor material can directly absorb microwave energy, thereby generating vibration or rotation to achieve low-temperature annealing. The long wavelength of microwave has high permeability, which is very suitable for the development of simultaneous annealing of multiple wafers to achieve the effect of increasing productivity.
