Optically aligning a silicon chip (1, 2) with respect to a frame of reference, the chip (1, 2) having a protective guard (3, 4) covering delicate microscopic structures on its surface, by using fiducials (5, 6) on the surface to optically align the chip (1, 2) with a microscope and forming the guard (3, 4) without compromising the protection it provides. |
