    摘要: A polysilicon structure and method of forming the polysilicon structure are disclosed, where the method includes a two-step deposition and planarization process. The disclosed process reduces the likelihood of defects such as voids, particularly where polysilicon is deposited in a trench having a high aspect ratio. A first polysilicon structure is deposited that includes a trench liner portion and a first upper portion. The trench liner portion only partially fills the trench, while the first upper portion extends over the adjacent field isolation structures. Next, at least a portion of the first upper portion of the first polysilicon structure is removed. A second polysilicon structure is then deposited that includes a trench plug portion and a second upper portion. The trench is filled by the plug portion, while the second upper portion extends over the adjacent field isolation structures. The second upper portion is then removed.

    摘要: A method for depositing a barrier layer onto a substrate is disclosed. A layer of titanium (Ti) is deposited onto the substrate using an ionized metal plasma (IMP) physical vapor deposition process. The IMP process includes: generating gaseous ions, accelerating the gaseous ions towards a titanium target, sputtering the titanium atoms from the titanium target with the gaseous ions, ionizing the titanium atoms using a plasma, and depositing the ionized titanium atoms onto the substrate to form the layer of Ti. A first layer of titanium nitride (TiN) is deposited onto the layer of Ti using a metal organic chemical vapor deposition (MOCVD) process. A second layer of TiN is deposited onto the first layer of TiN using a thermal chemical vapor deposition process. The newly completed barrier layer is annealed in the presence of nitrogen at a temperature of between about 500° C. to about 750° C.
