Abstract

The present invention is quick wafer annealing method inside one quick annealing apparatus. The quick annealing process includes two steps. In the first step, the quick annealing parameter is monitored and judged whether to exceed some range, which is the first normal annealing parameter plus / minus one first certain set value. In the second step, the quick annealing parameter is monitored and judged whether to exceed some range, which is the second normal annealing parameter plus / minus one second certain set value. The said process can detect the stability, and in case the annealing process is unstable, the quick annealing process is stopped to avoid the wafer loss.

Description

technical field [0001] The present invention relates to a heat treatment method in the field of metallurgy or a thermal process in equipment, in particular to a rapid thermal annealing method capable of detecting the stability of a rapid thermal annealing (Rapid Thermal Annealing, RTA) process and avoiding wafer scrapping . Background technique [0002] In the semiconductor manufacturing process, the commonly used thermal process is to use a thermal furnace tube or a rapid thermal annealing process, and the rapid thermal annealing process can be completed in a relatively short time compared with the thermal furnace tube. Thermal process, so its thermal budget (Thermal Budget) is quite low, so it is quite suitable for the semiconductor process that must control the diffusion and profile of dopants. [0003] see figure 1 , is a schematic diagram of a conventional rapid thermal annealing device 100 . When using the rapid thermal annealing apparatus 100 to carry out the therm...
