Abstract: Reusable composite stencils for spray processes, particularly for spray processes used in the fabrication of integrated circuit devices, may be fabricated having a permanent core and at least one sacrificial material layer. Thus, in operation, when a predetermined amount of the sacrificial material layer has been ablated away by a material being sprayed in the spray process, the remaining sacrificial material layer may be removed and reapplied to its original thickness. Therefore, the permanent core, which is usually expensive and/or difficult to fabricate, may be repeatedly reused.
