Schottky diode

A Schottky diode comprising:

• a substrate or other supporting body or structure;
• a first electrode formed directly or indirectly on a first region of a surface of the substrate or other supporting body or structure;
• a second electrode;
• and
• a body of semiconductive material connected to the first electrode at a first interface and connected to the second electrode at a second interface,
• wherein
• the first interface comprises a first planar region lying in a first plane and the first electrode has a first projection onto the first plane in a first direction normal to the first plane,
• the second interface comprises a second planar region lying in a second plane and the second electrode has a second projection onto the first plane in said first direction,
• at least a portion of the second projection lies outside the first projection,
• one of the first interface and the second interface provides a Schottky contact,
• said body comprises a first side and a second side, said second side being spaced from the first side by a thickness of said body in said first direction, and
• said first planar region being on said first side of the body and said second planar region being on said second side of the body,
• the Schottky diode further comprising a dielectric body arranged to cover at least a second region of said surface of the substrate or other supporting body or structure adjacent the first region,
• wherein said body of semiconductive material comprises a first portion, arranged over the first electrode and connected to the first electrode at said first interface, and a second portion arranged over a portion of the body of dielectric material covering said second region,
• and wherein said second electrode is formed at least partly on said second portion of the body of semiconductive material,
• wherein a portion, but not all, of said first projection lies inside said second projection,
• and wherein a projection, in the first direction, of the second planar region onto the first plane lies completely outside a projection, in the first direction, of the first planar region onto the first plane.
