    摘要: A ramp activated low temperature quality epitaxial growth process. A substrate is pre-conditioned and a passivation layer overlying the substrate surface is formed. The substrate is introduced into a process chamber having a controlled temperature. A process chamber purge technique is used to remove oxygen and contaminants from the process chamber before epitaxial growth begins. A process gas, which has an epitaxial growth species, a process chamber purging species and other possible species, is introduced into the process chamber at a low temperature. The process gas and the passivation layer keep the process chamber environment and the substrate surface free from contamination and free from native oxide growth before and, in some cases, during epitaxial growth. The process chamber temperature is gradually elevated to initiate a quality epitaxial growth by starting growth relative to decomposition of the passivation layer.

    摘要: A method for forming an improved copper inlaid interconnect (FIG. 11) begins by performing an RF preclean operation (408) on the inlaid structure in a chamber (10). The RF preclean rounds corners (210a and 206a) of the structure to reduce voiding and improve step coverage while not significantly removing copper atoms from the underlying exposed copper interconnects surfaces (202a). A tantalum barrier (220) is then deposited where one portion of the tantalum barrier is more tensile than another portion of the tantalum barrier. After formation of the barrier layer (220), a copper seed layer (222) is formed over a top of the barrier layer. The copper layer is formed while clamping the wafer with an improved clamp (85) which reduces copper peeling and contamination at wafer edges. Copper electroplating and chemical mechanical polishing (CMP) processes are then used to complete the copper interconnect structure.

    摘要: A method for forming an improved copper barrier layer begins by providing a silicon-containing layer (10). A physical vapor deposition process is then used to form a thin tantalum nitride amorphous layer (12). A thin amorphous titanium nitride layer (14) is then deposited over the amorphous tantalum nitride layer. A collective thickness of the tantalum nitride and titanium nitride layers 12 and 14 is roughly 400 angstroms or less. A copper material 16 is then deposited on top of the amorphous titanium nitride wherein the composite tantalum nitride layer 12 and titanium nitride layer 14 effectively prevents copper from diffusion from the layer 16 to the layer 10.

In accordance with one embodiment, a substrate (901) is placed into a chamber (30) that includes a coil (16) and a shield (14) wherein the coil and the shield are electrically isolated by an isolation/support member (32) having a first surface (321) that is substantially contiguous with a surface of the coil and having a second surface (322) that is substantially contiguous with a surface of the shield. A layer (1002, 1102) is then deposited onto the substrate (901).
