Abstract

Some embodiments include methods in which microwave radiation is used to activate dopant and/or increase crystallinity of semiconductor material during formation of a semiconductor construction. In some embodiments, the microwave radiation has a frequency of about 5.8 gigahertz, and a temperature of the semiconductor construction does not exceed about 500° C. during the exposure to the microwave radiation.
