ALL AROUND CONTACT DEVICE AND METHOD OF MAKING THE SAME

摘要

A device is provided that comprises a first pillar disposed in a first region and overlying a base structure, and a second pillar disposed in a second region and overlying the base structure and being spaced apart from the first pillar by a device region. A bridge is disposed in the device region with a first end connected to the first pillar and a second end connected to the second pillar. The bridge includes a top, sides, and a bottom. The bridge is formed from one or more heterostructures with an undercut opening extending from the bottom to an underlying structure. A four-sided conductive contact wraps around and substantially surrounds the bridge around its top, its sides, and its bottom along at least a portion of its length between the first and second end.

1. A device comprising:
a first pillar disposed in a first region and overlying a base structure; a second pillar disposed in a second region and overlying the base structure and being spaced apart from the first pillar by a device region; a bridge disposed in the device region with a first end connected to the first pillar and a second end connected to the second pillar, the bridge having a top, sides, and a bottom, the bridge being formed from one or more heterostructures with an undercut opening extending from the bridge to an underlying structure; and a four-sided conductive contact that wraps around and substantially surrounds the bridge around its top, its sides and its bottom along at least a portion of its length between the first and second end.
