Abstract: A method is disclosed for eliminating potential video echo effect for a collaboration session that utilizes AR environments. During the collaboration session and in the local AR environment, a contact overlap mask is generated that identifies a content overlap region where the projected remote content superimposes over the physical object placed on the local workspace surface. Based on the contact overlap mask, the local AR environment is temporarily modified throughout a short time period when the projected remote content is prevented from superimposing over the physical object within the content overlap region. A local image is generated based on the temporarily modified local AR environment and sent to the remote workstation for sharing in the collaboration session. By excluding any projected remote content from superimposing over the physical object in the local image, a potential video feedback loop is eliminated so as to eliminate any potential video echo effect.

Abstract: A disclosed structure includes a section (e.g., an always on (AON) section) with at least one N-channel transistor (NFET) and at least one P-channel transistor (PFET). The structure further includes a switch with first and second inputs connected to receive positive and negative bias voltages, respectively, and first and second outputs connected to bias back gates of the NFET(s) and PFET(s), respectively, of the section. The structure is also configured to generate select signals for controlling the input-to-output connections established by the switch. In a power saving mode, these signals cause the switch to establish input-to-output connections resulting only in reverse back biasing of the NFET(s) and PFET(s) of the section. In a functional mode, these signals can cause the switch to establish input-to-output connections resulting in either forward back biasing or reverse back biasing. Also disclosed is a method of operating the structure.

Abstract: Disclosed is a structure with ultralow-K (ULK) dielectric-gap wrapped contact(s). The structure includes an opening, which extends through a dielectric layer and is aligned above a device. A contact is within the opening and electrically connected to the device. Instead of the contact completely filling the opening, a ULK dielectric-gap (e.g., an air or gas-filled gap or a void) at least partially separates the contact from the sidewall(s) of the contact opening and further wraps laterally around the contact. Also disclosed is a method for forming the structure and, particularly, for forming a ULK dielectric-gap by etching back an exposed top end of an adhesive layer initially lining a contact opening to form a gap between the sidewall(s) of the opening and the contact and then capping the gap with an additional dielectric layer such that the gap is filled with air or gas or is under vacuum.

An insulator layer is on the substrate and extends laterally over the waveguide and a semiconductor layer is on the insulator layer. Additionally, depending upon the embodiment, an additional waveguide can be aligned above the substrate-embedded waveguide either on the isolation region or on a waveguide extender that extends at least partially through the isolation region and the insulator layer to the waveguide.
