A method for forming a component for use in a gas turbine engine, such as a turbine vane construction is provided. The discharge device provides a discharge path between a first power rail and a second power rail when the discharge device is activated. The first principal surface includes a window area from which a metallization layer and an emitter layer of the semiconductor assembly are masked, such that laser light emitted from the laser assembly impinges through the window area directly onto a base layer of said semiconductor assembly to initiate current conduction by said switching device.
