    摘要: A porous dielectric material such as silica-based aerogel is used as the dielectric layer 48 between the gate and the cathode on the emitter plate 12 of a field emission device. Aerogel, which can have a relative dielectric constant as low as 1.03, is deposited over the resistive layer 44 of the emitter plate 12. Metal layer 49, functioning as the gate electrode, is subsequently deposited over the aerogel layer 48. The use of aerogel as a gate dielectric reduces power consumption. In a disclosed embodiment, aerogel layer 48 is comprised of sublayers 48a, 48b, and 48c of aerogels of differing densities, thereby providing better adhesion of the aerogel gate dielectric to both the resistive layer 44 and metal layer 49. Methods of fabricating the aerogel gate dielectric are disclosed.

    摘要: A method of forming a field effect transistor includes forming a channel region within bulk semiconductive material of a semiconductor substrate. Source/drain regions are formed on opposing sides of the channel region. An insulative dielectric region is formed within the bulk semiconductive material proximately beneath at least one of the source/drain regions. A method of forming a field effect transistor includes providing a semiconductor-on-insulator substrate, said substrate comprising a layer of semiconductive material formed over a layer of insulative material. All of a portion of the semiconductive material layer and all of the insulative material layer directly beneath the portion are removed thereby creating a void in the semiconductive material layer and the insulative material layer. Semiconductive channel material is formed within the void. Opposing source/drain regions are provided laterally proximate the channel material. A gate is formed over the channel material. Integrated circuitry includes a bulk semiconductor substrate. A field effect transistor thereon includes a gate, a channel region in the bulk semiconductor substrate, and source/drain regions within the substrate on opposing sides of the channel region. A field isolation region is formed in the bulk semiconductor substrate and laterally adjoins with one of the source/drain regions. The field isolation region includes a portion which extends beneath at least some of the one source/drain region. Other aspects are contemplated.
