Abstract: A method includes providing a fin extending from a substrate, the fin including a plurality of semiconductor channel layers, and where a gate is disposed over the fin. A first spacer layer is deposited over the gate and over the fin in a source/drain region. The first spacer layer has a first etch rate. A second spacer layer is deposited over the first spacer layer. The second spacer layer has a second etch rate less than the first etch rate. The plurality of semiconductor channel layers are removed from the source/drain region to form a trench having a funnel shape. After forming the trench, inner spacers are formed along a sidewall surface of the trench. In various embodiments, lateral sidewall surfaces of each semiconductor channel layer of the plurality of semiconductor channel layers is substantially free of an inner spacer material.

Abstract: An integrated circuit (IC) structure includes a gate structure, a source epitaxial structure, a drain epitaxial structure, a front-side interconnection structure, a backside dielectric layer, and a backside via. The source epitaxial structure and the drain epitaxial structure are respectively on opposite sides of the gate structure. The front-side interconnection structure is on a front-side of the source epitaxial structure and a front-side of the drain epitaxial structure. The backside dielectric layer is on a backside of the source epitaxial structure and a backside of the drain epitaxial structure and has an air gap therein. The backside via extends through the backside dielectric layer to a first one of the source epitaxial structure and the drain epitaxial structure.

Abstract: A mobile device includes a biological information detecting device and a wireless communication interface. The mobile device uploads the biological characteristic to the server. The server generates a token that corresponds to the biological characteristic and transmits the token to the mobile device. The mobile device transmits the token to the verification terminal device. The verification terminal device can confirm the identity of the user by verifying the token. This modularizes the process of identity verification, replacing the verification process of applications that need to verify identity, so that these applications do not need to bear the cost of identity verification after interfacing with the identity verification system.
