A slim lens assembly includes a first lens, a second lens, a third lens, a fourth lens and a fifth lens, all of which are arranged in sequence from an object side to an image side along an optical axis. The color data in each small region are classified to the present group, and plural components are selected in descending order of the variance from the representative color obtained from each group. The phase shift mask is manufactured by first forming a layer of opaque material on a transparent mask substrate. The object is removed from the solvent and allowed to dry, producing a smooth finished part. A cavity is defined between the interior of the cup-shaped terminal body and the cluster block, and a dielectric material substantially fills at least one of the cavity and the cluster block free volume.
