    摘要: A method is described for forming gate structures with different metals on a single substrate. A thin semiconductor layer (26) is formed over gate dielectric (24) and patterned to be present in a first region (16) not a second region (18). Then, metal (30) is deposited and patterned to be present in the second region not the first. Then, a fully suicided gate process is carried out to result in a fully suicided gate structure in the first region and a gate structure in the second region including the fully suicided gate structure above the deposited metal (30).

    摘要: Method of manufacturing a semiconductor device comprising MOS transistors having gate electrodes (15, 16) formed in a number of metal layers (8, 9, 13; 8, 12, 13) deposited upon one another. In this method, active silicon regions (4, 5) provided with a layer of a gate dielectric (7) and field-isolation regions (6) insulating these regions with respect to each other are formed in a silicon body (1). Then, a layer off a first metal (8) is deposited in which locally, at the location of a part of the active regions (4), nitrogen is introduced. On the layer of the first metal, a layer of a second metal (13) is then deposited, after which the gate electrodes are etched in the metal layers. Before nitrogen is introduced into the first metal layer, an auxiliary layer of a third metal (9) which is permeable to nitrogen is deposited on the first metal layer. Thus, the first metal layer can be nitrided locally without the risk of damaging the underlying gate dielectric. Substantial changes of the metal work function are possible, and a semiconductor device comprising NMOS and PMOS can be realized.

    摘要: The invention relates to a method of manufacturing a semiconductor device (10) with a field effect transistor, in which method a semiconductor body (1) of a semiconductor material is provided, at a surface thereof, with a source region (2) and a drain region (3) and with a gate region (4) between the source region (2) and the drain region (3), which gate region comprises a semiconductor region (4A) of a further semiconductor material that is separated from the surface of the semiconductor body (1) by a gate dielectric (5), and with spacers (6) adjacent to the gate region (4), for forming the source and drain regions (2,3), in which method the source region (2) and the drain region (3) are provided with a metal layer (7) which is used to form a compound (8) of the metal and the semiconductor material, and the gate region (4) is provided with a metal layer (7) which is used to form a compound (8) of the metal and the further semiconductor material. The known method in which different metal layers are used to silicidate source and drain regions and gate regions (2,3,4) has several drawbacks. A method according to the invention is characterized in that before the spacers (6) are formed, a sacrificial region (4B) of a material that may be selectively etched with respect to the semiconductor region (4A) is deposited on top of the semiconductor region (4A), and after the spacers (6) have been formed, the sacrificial layer (4B) is removed by etching, and after removal of the sacrificial layer (4B), a single metal layer (7) is deposited contacting the source, drain and gate regions (2,3,4). This method is on the one hand very simple as it requires only a single metal layer and few, straight-forward steps and it is compatible with existing (silicon) technology, and on the other hand it results in a (MOS)FET which does not suffer from a depletion layer effect in the fully silicided gate (4).
