    摘要: An integrated circuit capacitor is disclosed which has improved leakage and storage characteristics. The dielectric material for the capacitor consists of a first layer of silicon nitride adjacent the lower plate, such as a silicon substrate, upon which a layer of silicon dioxide is formed. A second layer of silicon nitride is formed over the silicon dioxide layer, above which the second plate is formed. The layer of silicon dioxide may be formed by the partial oxidation of the first silicon nitride layer. The capacitor may be a planar capacitor, may be formed in a trench, or may be formed between two layers above the surface of the substrate.

    摘要: A dynamic random access memory device (10) includes three separate sections--an input/output section (12), a peripheral transistor section (14), and a memory array section (16), all formed on a p- type substrate layer (18). The dynamic random access memory device (10) can employ separate substrate bias voltages for each section. The input/output section (12) has a p- type region (22) that is isolated from the p- type substrate layer (18) by an n-type well region (20). The peripheral transistor section (14) has a p- type region (36) that can be isolated from the p- type substrate layer (18) by an optional n- type well region (40) for those devices which require a different substrate bias voltage between the peripheral transistor section (14) and the memory array section (16).

    摘要: A field effect transistor with a dual-counterdoped channel is disclosed. The transistor features a channel comprising a first doped region (28) and a second doped region (26) underlying the first doped region. A source and drain (32) are formed adjacent to the channel. In one embodiment of the present invention, the first doped region (28) is doped with arsenic, while the second doped region (26) is doped with phosphorus. The high charge-carrier mobility of the subsurface channel layer (28) allowing a lower channel dopant concentration to be used, which in turn allows lower source/drain pocket doping. This reduces the capacitance and response time of the transistor.
