Abstract:
A microactuator comprising:a substrate; input lines adapted to apply a drive voltage and signals to an upper electrode; a lower electrode formed on an upper surface of said substrate; a piezoelectric element formed on a n upper surface of said lower electrode, said piezoelectric element being provided, at a portion to be connected with said input lines, with at least one etched groove to have a gently inclined lateral surface at said portion; and said upper electrode formed over said piezoelectric element in such a fashion that it extends from an upper surface of said piezoelectric element to said gently inclined lateral surface, said upper electrode being connected to said input lines; whereby said connection between said upper electrode and said input lines is improved; further comprising: an insulating layer formed on a portion of said lower electrode exposed an etched portion of said piezoelectric element.
