  • Patent number: 7863136
    Abstract: A method of manufacturing integrated circuits including a FET with a gate spacer. One embodiment provides forming a lamella of a semiconductor material and two insulator structures on opposing sides of the lamella. The lamella is recessed. A fin is formed from a central portion of the lamella. The fin is thinner than a first and a second portion of the lamella which face each other on opposing sides of the fin. A first spacer structure is formed which encompasses a first portion of the fin, the first portion adjoining to the first lamella portion. A gate electrode is disposed adjacent to the first spacer structure and encompasses a further portion of the fin on a top side and on two opposing lateral sides.

  • Patent number: 7692246
    Abstract: The present invention provides a FinFET transistor arrangement produced using a method with the steps: providing a substrate (106, 108); forming an active region (1) on the substrate a fin-like channel region (113b?; 113b?). Formation of the fin-like channel region (113b?; 113b?) has the following steps: forming a hard mask (S1-S4) on the active region (1); anisotropic etching of the active region (1) using the hard mask (S1-S4) forming STI trenches (G1-G5) having an STI oxide filling (9); polishing-back of the STI oxide filling (9); etching-back of the polished-back STI oxide filling (9); selective removal of components of the hard mask forming a modified hard mask (S1?-S4?); anisotropic etching of the active region (1) using the modified hard mask (S1?-S4?) forming widened STI trenches (G1?-G5?), the fin-like channel regions (113b?; 113b?) of the active region (1) remaining for each individual FinFET transistor.

  • Publication number: 20090086523
    Abstract: An integrated circuit comprises a memory cell array portion and a support circuitry portion. The memory cell array portion comprises at least one bitline and at least one wordline, which is disposed above the bitline. The support circuitry portion comprises a FinFET comprising a gate electrode. An upper side of a portion of the gate electrode is disposed at the same height as an upper side of a portion of the bitline. A method of manufacturing an integrated circuit comprises the steps of forming a memory cell array and forming a support circuitry. The step of forming the memory cell array comprises forming a bitline and forming a wordline disposed above the bitline. The step of forming the support circuitry comprises forming a FinFET. The step of forming the FinFET comprises forming a gate electrode, an upper side of a portion of the gate electrode being formed at the same height as an upper side of a portion of the bitline.
