    Abstract: Semiconductor devices having thin bodies of a semiconductor material are made from a wafer of the semiconductor material which is thicker than the bodies of the devices. The thicker wafer is provided with spaced thinner portions of the desired area and thickness of the bodies of the devices to be formed by etching recesses in one surface of the wafer. The recesses are formed with flat bottoms which are of the desired area of the bodies of the devices. A masking layer is coated on the bottom of each of the recesses. The active region of each of the devices is formed at the other surface of the wafer over each of the recesses. The semiconductor material between the thin portions of the wafer is then removed by etching the wafer from the one surface of the wafer so as to separate the thin portions of the wafer to form the individual devices. During the last etching process the masking layers on the bottom of the recess protect the thin portions of the wafer from being etched.

    Abstract: The transistor is especially useful for high frequency switching applications. A conductive path between ohmic contacts will pass high frequency signals with very little impedance. The conductive path is comprised of a doped semiconductor layer of one conductivity type to which ohmic contacts are attached. The substrate of the device which underlies the layer is heavily doped with deep impurities of opposite conductivity type so that it has a high resistivity. The high resistivity of the substrate isolates the driving voltage used to switch the device from the signal passed between the ohmic contacts. The device can be turned ''''OFF'''' by reverse biasing the PN junction formed between the substrate and the layer. This is accomplished by imposing a driver voltage between one of the ohmic contacts and a metallic contact connected to the substrate.

    Abstract: A semiconductor device having at least two contacts on a body of semiconductor material. One of the contacts is in a plane spaced from the plane of the other contacts and the edges of the one contact are in substantial alignment with the adjacent edges of the other contacts. The material under either the edges of the one contact or the adjacent edges of the other contacts is removed so that such edges project in cantilever fashion beyond the material under the respective contact.
