    摘要: Method embodiments herein determine a connection order in which connections will be made to connect active devices to antennas within a given circuit design. The method also evaluates the possibilities that these connections to the antennas will cause charging damage in the devices that are connected to the antennas. Such possibilities are based on the connection order, the size of the antennas, and the likelihood that charges will flow from the antennas through insulators of the devices. If a significant possibility for damage exists, the method can reduce the size of the antenna.

    摘要: Methods of etching a semiconductor structure using ion milling with a variable-position endpoint detector to unlayer multiple interconnect layers, including low-k dielectric films. The ion milling process is controlled for each material type to maintain a planar surface with minimal damage to the exposed materials. In so doing, an ion beam mills a first layer and detects an endpoint thereof using an optical detector positioned within the ion beam adjacent the first layer to expose a second layer of low-k dielectric film. Once the low-k dielectric film is exposed, a portion of the low-k dielectric film may be removed to provide spaces therein, which are backfilled with a material and polished to remove the backfill material and a layer of the multiple interconnect metal layers. Still further, the exposed low-k dielectric film may then be removed, and the exposed metal vias polished.

    摘要: A method for forming a TiN layer on top of a metal silicide layer in a semiconductor structure without the formation of a thick amorphous layer containing Ti, Co and Si and the structure formed are provided. In the method, after a Ti layer is deposited on top of a metal silidide layer, a dual-step annealing process is conducted in which a low temperature annealing in a forming gas (or ammonia) at a temperature not higher than 500° C. is first conducted for less than 2 hours followed by a high temperature annealing in a nitrogen-containing gas (or ammonia) at a second temperature not lower than 500° for less than 2 hours to form the TiN layer. The present invention method prevents the problem usually caused by a thick amorphous material layer of Ti—Si—Co which produces weakly bonded Ti which reacts with fluorine atoms from WF6 during a subsequent CVD W deposition process and causes liner failure due to a volume expansion of the amorphous material. The maximum thickness of the amorphous material layer formed by the present invention method is less than 5 nm which minimizes the line failure problem.
