Abstract

Methods of connecting a circuit device to a semiconductor substrate and micro-fluid ejection devices made by the methods. One method includes printing an elongate strip of an electrically conductive fluid to electrically interconnect a first contact pad on a semiconductor substrate containing fluid ejection actuator devices with a second contact pad on an electrical trace circuit, wherein the electrical trace circuit is disposed adjacent to and spaced-apart from the semiconductor substrate. The electrically conductive fluid contains a liquid component and a conductive particle component. The liquid component is removed from the conductive particle component to provide a solid elongate strip of conductive material interconnecting the first contact pad and the second contact pad.
