Paper Title:
Annealing of Aluminum Implanted 4H-SiC: Comparison of Furnace and Lamp Annealing
  Abstract

Furnace annealing and lamp annealing of aluminum implanted layers in 4H silicon carbide (SiC) were investigated with respect to surface degradation and electrical parameters. A sheet resistance of about 20kW/ı was obtained for an aluminum implantation dose of 1.2×1015cm-2 and annealing in the furnace at 1700°C for 30min. For the same implantation dose, lamp annealing at 1770°C for 5min resulted in a three times higher sheet resistance of 60kW/ı. The surface roughness was best for the lamp system and stayed below 1nm for Al doses lower than 1×1015cm-2.
