Abstract
1275004 Making semi-conductor devices HITACHI Ltd 28 Aug 1970 [1 Sept 1969] 41584/70 Heading H1K The manufacture of individual semi-conductor units each containing one or more circuit elements can be appreciated from the two figures one of which shows the structure inverted with respect to the other. In the embodiment a monocrystalline silicon wafer 1 has a latticeform area 2 provided thereon (for example by the provision and etching of a layer of silicon particles, silicon oxide, silicon, nitride, or glass) such that in the subsequent overall deposition of silicon from a silane atmosphere monocrystalline zones 3 are formed which are separated from one another by a polycrystalline zone 4 formed over the area 2. The deposited silicon is of high resistivity and doped with arsenic or antimony. Low resistivity regions 5 are formed in the monocrystalline zones 3 by arsenic or antimony diffusion. The surface of the deposited silicon is covered with a layer 6 of silicon oxide, ceramic, or refractory metal. Parts of the layer 6 may be removed to allow heavy diffusion of boron into the polycrystalline zone 4. A handling layer 7 of polycrystalline silicon is then provided and the original, monocrystalline substrate 1 etched or lapped away. Base and emitter regions 8, 9 are formed by diffusion through a silicon oxide or silicon nitride layer 10 and beam leads 11, 12 formed from gold, chromium, molybdenum, or tungsten. The readily etched polycrystalline silicon of layer 7 and zone 4 is then etched away to separate the units, the layer 6 acting as an etch stop resulting in planar lower surfaces for the units.
