摘要： A modified TDEAT (tetrakisdiethylamino titanium) based MOCVD precursor for deposition of thin amorphous TiN:Si diffusion barrier layers. The TDEAT is doped with 10 at % Si using TDMAS (trisdimethlyaminosilane); the two liquids are found to form a stable solution when mixed together. Deposition occurs via pyrolysis of the vaporised precursor and NH3 on a heated substrate surface. Experimental results show that we have modified the precursor in such a way to reduce gas phase component of the deposition when compared to the unmodified TDEAT-NH3 reaction. Deposition temperatures were the range of 250-450° C. and under a range of process conditions the modified precursor shows improvements in coating conformality, a reduction in resistivity and an amorphous structure, as shown by TEM and XRD analysis. SIMS and scanning AES have shown that the film is essentially stoichiometric in Ti:N ratio and contains low levels of C (˜0.4 at %) and trace levels of incorporated Si (0.01

摘要： This invention relates to a method of manufacturing a semiconductor device. In this method, a semiconductor device is provided comprising a substrate (10), the substrate (10) being covered with a low-k precursor layer (20) having a surface (25). After this step, a partial curing step is performed in which a dense layer (30) is formed at or near the surface (25) of a low-k precursor layer (20). This dense layer (30) can act as a protective layer (30). The low-k precursor material (20) is chosen from a group of materials having the property that they are applicable in a non-cured or partially cured state. The main advantage of this method is that no separate protective layer (30) needs to be provided to the low-k precursor layer (20), because the dense layer (30) is formed out of the low-k precursor layer (20) itself. The dense layer (30) therefore has a good adhesion to the low-k precursor layer (20).

摘要： A substrate processing system as illustrated at (1). A substrate (2) lies upon a piston (3) shown in both the loading position (3a) and in a processing position (3b). The substrate is loaded via a port (4) through a door (5). The loading area (7a), and/or the hole chamber (7) may be pumped out via a vacuum exhaust pipe (6) connected to a pump (not shown). A linear drive mechanism shown diagrammatically at (8) lifts the piston and the substrate in the chamber such that a process volume (7b) of the chamber is defined with poor gas conduction between the piston and the walls of the chamber.

摘要： To form a substantially closed void between two structures on a substrate, a flowable liquid dielectric material is deposited to fill partially the space between the structures, and a surface is placed to bridge and substantially close the space between the structures. The substrate is then inverted whilst maintaining the bridge and the deposited material is allowed to flow down to be substantially supported by the surface. The material is set in its substantially supported position, and the surface is removed.
