Patent ID: 7737470

Claim:
A high-frequency diode, comprising: a first semiconductor area having a first conductivity type; a barrier area adjacent to the first semiconductor area having a second conductivity type, the second conductivity type different than the first conductivity type; a second semiconductor area adjacent to the barrier area, the second semiconductor area having the second conductivity type and a dopant concentration of between zero and a first limit, the first limit being lower than a dopant concentration of the barrier area, wherein the barrier area has a dopant concentration between 10 16 and 10 17 dopant atoms per cm 3 ; and a third semiconductor area adjacent to the second semiconductor area, the third semiconductor area having a second conductivity type and a higher dopant concentration than the barrier area, wherein the barrier area has a thickness within a value range between 0.2 μm and 0.8 μm, wherein the second semiconductor area has a thickness within a value range between 5 μm and 8 μm.
