ABSTRACT:
An integrated circuit is formed on a substrate. The integrated circuit includes a transistor formed in the substrate. The transistor has a gate that forms at least one closed-loop. The integrated circuit also includes an ejection element that is coupled to the transistor wherein the ejection element is disposed over the substrate without an intervening field oxide layer.
