Abstract: Some implementations herein describe a carrier structure and techniques of forming a semiconductor device using the carrier structure. The carrier structure includes a core layer formed from a layer of a high bandgap material, a backside layer stack formed on a backside surface of the layer of the high bandgap material, and a frontside layer stack formed on a frontside surface of the layer of the high bandgap material. The backside layer stack includes a backside chucking layer (e.g., a layer of a polysilicon material) that intervenes between a backside diffusion barrier layer and a backside adhesion layer. The frontside layer stack includes a corresponding frontside diffusion barrier layer that interfaces directly with a corresponding frontside adhesion layer. A corresponding frontside chucking layer has been eliminated.

Abstract: An advertisement playing and monitoring system uses a remote control system to transmit an advertisement file to an advertisement processing machine. The advertisement processing machine stores the advertisement file in a storage unit and plays the advertisement file on a display unit by an image-processing unit. The advertisement processing machine utilizes the image-processing unit to store the images of the display unit in the storage unit for being viewed by a remote monitoring system. Alternatively, the remote control system plays the advertisement file on the display unit via the advertisement processing machine. The remote monitoring system receives the images of the display unit via the advertisement processing machine.
