A multi-speed burst mode serializerde-serializer is configurable and can operable in one of a plurality of operating modes. A controller receives the position signals from the vision system, determines the substrate position, and sends transport signals to a robot arm. The p-electrode includes a reflective first material in direct contact with a first portion of the p-type region and a second material in direct contact with a second portion of the p-type region adjacent to the first portion. Thus, increasing the additive frame in number even without decreasing the image shooting frame rate at a low-speed shooting of the image allows such an image signal DVj shot at the low speed to be obtained. An AT receiving forward link signals from multiple ATs identifies the AT associated with the highest quality forward link signal.
