ABSTRACT:
A process for producing a semiconductor service of the type having a semiconductor substrate; a semiconductor layer disposed on the semiconductor substrate; a first element formed in a region of the semiconductor layer and having a perimeter including a bottom; a second element formed in another region of the semiconductor layer; an insulating layer surrounding the perimeter of the first element, for electrically insulating and separating the first element from the second element and the semiconductor substrate; an electrical shield layer disposed between the insulating layer and the first element, surrounding the perimeter of the first element, and adapted to a reference electric potential applied thereto, for shielding the first element from an electrical fluctuation of the semiconductor substrate caused by the second element; and an electrode for applying the reference electric potential to the electrical shield layer.
