Abstract: An apparatus includes a spray module with at least one column of spray nozzles. Each spray nozzle is configured to deliver a processing substance on a semiconductor substrate during a process for semiconductor manufacturing as the semiconductor substrate moves past the spray module. The at least one column of spray nozzles is arranged with respect to a direction of travel of the semiconductor substrate so the semiconductor substrate passes the spray nozzles. A location module identifies a location of the semiconductor substrate with respect to the spray module. A spray pattern module determines a spray pattern of where a processing substance is to be delivered to the semiconductor substrate and a nozzle control module actuates each spray nozzle independently based on the spray pattern and a location of the semiconductor identified by the location module.

Abstract: A method and structures are provided for implementing enhanced reliability for printed circuit board high power dissipation applications. An external return current member provides a return current path outside of the printed circuit board, thereby minimizing power dissipation within the printed circuit board. The external return current member can be implemented with an associated stiffener formed of electrically conductive material. Alternatively, the external return current member can be implemented with a sheet of electrically conductive material with an insulator provided between the sheet and the associated stiffener.
