A semiconductor structure provides lower parasitic capacitance between the gate electrode and contact vias while providing substantially the same level of stress applied by a nitride liner as conventional MOSFETs by reducing the height of the gate electrode and maintaining substantially the same height for the gate spacer. The nitride liner contacts only the outer sidewalls of the gate spacer, while not contacting inner sidewalls, or only a small area of the inner sidewalls of the gate spacer, therefore applying substantially the same level of stress to the channel of the MOSFET as conventional MOSFETs. The volume surrounded by the gate spacer and located above the gate electrode is either filled with a low-k dielectric material or occupied by a cavity having a dielectric constant of substantially 1.0. The reduced height of the gate electrode and the low-k dielectric gate filler or the cavity reduces the parasitic capacitance.

A plate-fin heat exchanger having a plurality of layers for indirectly exchanging heat between two or more fluids. The heat exchanger is provided with two sections and inlets and outlets to the sections to cause streams of the fluids to flow within the two sections parallel to the length of the heat exchanger between central locations and the ends of the heat exchanger. In such manner, the cross-sectional flow area of such a heat exchanger is greater than the heat exchanger in which the flow is from one end to the other end of the heat exchanger. This increase in cross-sectional flow area reduces the pressure drop within the heat exchanger.
