Patent number: 7537997Abstract: Mechanisms for ensuring the migratability of circuits into future technologies while minimizing fabrication costs and maintaining or improving power efficiency are provided. A mask layer is introduced to portions of the integrated circuit prior to a stress inducing layer being applied to the integrated circuit. In an exemplary embodiment, a tensile or compressive film is applied to the devices on the integrated circuit chip but is removed from those devices whose operation is to be modified. Thereafter, a tensile or compressive strain layer is applied to the devices whose film was removed. An additional mask layer may then be used to effect a halo or well implant to relax the strain on the devices not being protected by the mask layer. In this way, the current of the non-protected devices is reduced back to its original target design point.Type: GrantFiled: May 5, 2008Date of Patent: May 26, 2009Assignee: International Business Machines CorporationInventors: Stephen L.

Patent number: 7538040Abstract: A method for patterning CNTs on a wafer wherein a CNT layer is provided on a substrate, a hard mask film is deposited on the CNT layer, a BARC layer (optional) is coated on the hard mask film, and a resist is patterned on the BARC layer (or directly on the hard mask film if the BARC layer is not included).
