RADIO FREQUENCY DEVICE AND METHOD OF FABRICATING THE SAME

摘要

PURPOSE: A radio frequency device and a method of fabricating the same are provided to reduce the contact resistance of a guard ring contact plug by forming an impurity doping region in the surface of the guard ring. CONSTITUTION: A substrate(102) comprises a first area(102a) and a second part(102b). A semiconductor layer(106) is formed on the first area of the substrate. A buried insulating layer(104) is formed between the substrate and the semiconductor layer. A plurality of inversion blocking layers(120a) is formed on the second region of the substrate. A field insulating layer(125) covers the side of the semiconductor layer and the top side of the inversion blocking layer.
