A method for fabricating a thermal inkjet head equipped with a symmetrical heater and the head fabricated by the method are provided. The device includes a linear image sensor that incorporates an array of CMOS light sensors. Since the marangoni dryer is adhered to the bath during drying, the wafers are not affected by laminar flow or exhaustion and water marks do not occur thereon. A conductive coil is coupled to the cylindrical sleeve to provide sensing of a position of the piston. The system configuration file identifies the at least one component and is stored remote from the security system. A second absorption well layer has a layer thickness \xbd or less of that of a first absorption well layer thickest in one period, and a coupling barrier layer has a layer thickness smaller than that of an exit barrier layer thickest in one period.
