An aqueous composition suitable for use as a high-retention sanitizer, especially on irregular andor non-horizontal surfaces and surfaces on which water does not readily spread, a method for sanitizing a surface using the composition, and kits comprising components of the composition. The apparatus can be a head up display or head worn display and can include image sources disposed at a respective image source position, and a combiner detached from the image sources. By providing additional metal routing in the lower gate regions that may be coupled to the upper metal layers, the spacing requirements of the upper metal layers may be eased, while maintaining the size of the semiconductor device.
