Abstract: A method for fabricating a semiconductor device having a silicided gate that is directed to forming the silicided structures while maintaining gate-dielectric integrity. Initially, a gate structure has, preferably, a poly gate electrode separated from a substrate by a gate dielectric and a metal layer is then deposited over at least the poly gate electrode. The fabrication environment is placed at an elevated temperature. The gate structure may be one of two gate structures included in a dual gate device such as a CMOS device, in which case the respective gates may be formed at different heights (thicknesses) to insure that the silicide forms to the proper phase. The source and drain regions are preferably silicided as well, but in a separate process performed while the gate electrodes are protected by, for example a cap of photoresist or a hardmask structure.

Abstract: A process used to create a non-smooth, top surface topography, for a semiconductor substrate, needed to improve the adhesion between a protective molding compound, and the underlying top surface of the semiconductor substrate, has been developed. The process features the creation of the non-smooth, top surface topography, including either: recessed, or etched back, copper damascene structures, in an insulator layer; or copper damascene structures, in a recessed, or etched back, insulator layer. The recessing of the copper damascene structures, or of the insulator layer, is accomplished via selective, dry or wet etch procedures. After formation of a gold wire bond, on the top surface of a copper damascene structure, a protective molding compound is applied, to the underlying, non-smooth, top surface topography.

Abstract: A structure for forming an ohmic contact to the drain of a MOSFET in a stacked capacitor DRAM cell is described. The contact is formed by making an opening in the upper cell plate of the cells capacitor and contacting the storage plate through this opening with a conductive plug, preferably a tungsten plug. The plug is formed concurrent with the conventional contact and first metal wiring processing of the DRAM. The contact is used in DRAM test arrays for characterizing the quality of MOSFET gate insulator as well as the performance characteristics of the MOSFET itself. Connection to the conductive plug is made with first metal wiring. The test structures can be built at any position within the array and since they are located above the polysilicon bitline/wordline structure, the metal connection lines for the contacts do not interfere with the structure of the test array itself other than the sacrifice of the test cell from the array.
