Abstract: The invention concerns an integrated circuit or chip comprising an original support and active and passive microscopic functional elements present in a thin layer made of a monocrystalline semiconductor material. The invention is characterised in that the original support (1) is refractory and transparent, and is coated on one of its surfaces with a thin layer (3) of transparent and insulating inorganic refractory material, said thin layer (3) being itself coated with a thin layer (4) of monocrystalline inorganic semiconductor material, in particular of the silicon or silicon-germanium type, which contains the active functional elements (13-14) and which supports the transparent passive functional elements (15 and 16), other opaque functional elements (17 and 18) being punctually arranged to leave out the transparent cells (12) through which the visible spectrum light can freely pass through the chip entirely.
