摘要： A new method to form metal silicide gates in the fabrication of an integrated circuit device is achieved. The method comprises forming polysilicon lines overlying a substrate with a dielectric layer therebetween. A first isolation layer is formed overlying the substrate and the sidewalls of the polysilicon lines. The first isolation layer does not overlie the top surface of the polysilicon lines. The polysilicon lines are partially etched down such that the top surfaces of the polysilicon lines are below the top surface of the first isolation layer. A metal layer is deposited overlying the polysilicon lines. A thermal anneal is used to completely convert the polysilicon lines to metal silicide gates. The unreacted metal layer is removed to complete the device.

摘要： A method for forming a field effect transistor device employs a self-aligned etching of a semiconductor substrate to form a recessed channel region in conjunction with a pair of raised source/drain regions. The method also provides for forming and thermally annealing the pair of source/drain regions prior to forming a pair of lightly doped extension regions within the field effect transistor device. In accord with the foregoing features, the field effect transistor device is fabricated with enhanced performance.

摘要： A process for forming a composite insulator spacer on the sides of a MOSFET gate structure, has been developed. The process features formation of additional insulator spacer shapes on top portions of sides of a gate structure in which an initial insulator spacer had been removed during an over etch cycle used for definition of the initial insulator spacer. The re-establishment of insulator spacer shapes provides a composite insulator spacer offering reduced risk of gate to substrate leakage or shorts, that can occur during a subsequent salicide procedure from the presence of metal silicide stringers or ribbons formed on, and residing on the composite insulator spacer.

摘要： The present invention provides a method improving the adhesion between inter metal dielectric (IMD) layers by performing a HF dip etch to treat the surface of an oxide, silicon nitride or Silicon oxynitride insulating layer before an overlying low-K layer is formed. The present invention provides a method of fabricating a low-K IMD layer 20 over an oxide, Silicon oxynitride (SiON), or nitride IMD layer 14 with improved adhesion. First, a 1st inter metal dielectric (IMD) layer 14 is formed over a substrate. Next, the invention's novel HF dip etch is performed on the 1st IMD layer 14 to form a treated surface 16. Next, a 2nd BMD layer composed of a low-K material is formed over the rough surface 16 of the 1st IMD layer 14. The treated surface 16 improves the adhesion between a 1st IMD layer oxide (oxide, SiN or SiON) and a low k layer. Subsequent photoresist strip steps do not cause the 1st IMI layer 14 and the 2nd IMD layer 20 (low-K dielectric) to peel.

Over a semiconductor surface are successively deposited an etch stop layer, a layer of dielectric and a hard mask layer. An opening is etched in the hard mask layer, the main opening is etched through the layer of dielectric and the etch stop layer.

摘要： A process used to prevent attack of an aluminum based structure, exposed in a non-fully landed via hole, from solvents used during the wet stripping cycle, performed to remove the via hole defining photoresist shape, has been developed. The process features the formation of a protective aluminum oxide layer, on the exposed side of the aluminum based structure, via use of a plasma treatment, performed in an H.sub.2 O/N.sub.2 ambient. The H.sub.2 O/N.sub.2 plasma treatment procedure is performed after a dry plasma, photoresist stripping step, but prior to a final wet photoresist stripping step. The aluminum oxide layer offers protection of the exposed regions of the aluminum structure, located in the non-fully landed via hole, from reaction or corrosion, that can result from exposure of aluminum to the solvents used in the final wet photoresist stripping cycle.
