    Abstract: PROBLEM TO BE SOLVED: To reduce or essentially remove a salient or a protrusion which generally extends upward from an almost plane surface of a polysilicon film that is formed by low-temperature poly Si (LTPS) annealing of an amorphous silicon film deposited on a substrate.
    SOLUTION: A flattening solution which is highly aqueous and strongly basic has a pH of 12 or higher and contains water, at least one kind of a strong base, and at least one kind of an etching speed control agent. The method of use thereof includes a process which makes the almost plane surface of polysilicon film contact with the solution which is highly aqueous and strongly basic for a sufficient time to make etching selectively the salient or the protrusion from the surface of the almost plane polysilicon film without etching significantly the almost plane polysilicon film.

    Abstract: PROBLEM TO BE SOLVED: To provide a MEMS capable of obtaining excellent element characteristics.SOLUTION: A MEMS manufacturing method comprises: a step of forming a lower electrode 12A on a substrate 10; a step of forming an auxiliary structure 13A which is brought into an electrically floating state so as to be adjacent to the lower electrode 12A, on the substrate 10; a step of forming a sacrificial film on the lower electrode 12A, the auxiliary structure 13A, and the substrate 10; a step of forming an upper electrode 16 on the sacrificial film; and a step of removing the sacrificial film and disposing the upper electrode 16 above the lower electrode 12A via a cavity 21A. The sacrificial films formed on the lower electrode 12A and the auxiliary structure 13A have a flat upper surface. The upper electrode 16 formed on the sacrificial film has a flat lower surface.

    Abstract: PROBLEM TO BE SOLVED: To reduce or essentially remove an upheaval or protrusion which generally extends upward from an almost plane surface of polysilicon film that is manufactured by low-temperature polysilicon silicon (LTPS) annealing of an amorphous silicon film deposited on a substrate.
    SOLUTION: The planarizing solution which is highly aqueous and strongly basic has a pH of 12 or more and contains water, at least one kind of strong base, and at least one kind of etching speed controlling agent.
