According to the invention, a layer made of an electrically insulating material is applied to a substrate and a component that is arranged thereupon in such way that said layer follows the surface contour formed by the substrate and the component. The elongate cable has a central axis and a receptacle with a radially inwardly facing conductive surface. The recording beam may cause to be formed, in the front focal plane of the lens, an optical distribution that represents the desired filter response of the VBG element. The computed table values are also scaled by the same scaling factor. A source region of the first conductivity type is then formed in an upper portion of the body region. Moreover, little or no insert size selection occurs with the present methods so that large as well as small nucleic acid inserts are readily inserted into the present vectors.
