    Abstract: Weighted lift pin constructions as disclosed may be used with a semiconductor fabrication processing apparatus. The weighted lift pin constructions comprise a lift pin and a weight element disposed along an end of the lift pin. The weight element is removably retained on the lift pin by a retaining element that may be a clip element, an O-ring element, and differently configured lift pin and weight element threaded sections. When the clip element or O-ring element used, the weight element includes a collar adjacent an end of an opening in the weight element to accommodate placement of the clip or O-ring element therein as retained on the lift pin to thereby maintain axial placement of the lift pin relative to the weight element. Such maintained axial placement may also be achieved by interference locked engagement between differently configured lift pin and weighted element threaded sections.
