Abstract
To realize uniform heating characteristic of 2.45-GHz-microwave-induced-heating system with a 330-mm-diameter heating unit of carbon heating tubes (CHTs), we installed a propeller-type-rotational antenna with two 120-mm-long blades with tilted angles of 45 and −45° and a height of 105 mm in 330-mm-diameter cavity with a modified rotating velocity optimized by the numerical simulation. The CHT heating at 800°C for 170 s reduced the sheet resistivity ranging from 60 to 80 Q/sq for 1.0×10 15 cnr=phosphorus implanted 300-mm-diameter silicon substrates. The average activation ratio Pay was 0.77 and its mean square deviation PRMSD was 0.05. They were better than Pay of 0.73 and PRMSD of 0.06 in the case of the CHT heating with no antenna.
