Abstract

We developed a method to dope phosphorus and aluminum into 4H-SiC by irradiating excimer laser light to 4H-SiC immersed in phosphoric acid solution or aluminum chloride solution. Phosphorus and aluminum are introduced at a concentration over 1020 /cm3 near the crystal surface. We produced a pn junction, and the pn junction shows a rectifying characteristic whose ideality factor is nearly unity.
