| 20120089953 | MASK LAYOUT FORMATION - A method for mask layout formation including forming a plurality of phase shapes on either side of a critical feature of a design layout of an integrated circuit chip having a plurality of critical features, wherein each phase shape has an edge; identifying a plurality of transition edges from the edges, wherein each transition edge is parallel to a critical feature; identifying a transition space defined by one of a group including two transition edges, wherein the space is external to all phase shapes, and one transition edge, wherein the space is external to all phase shapes; forming a transition polygon by closing each transition space with at least one closing edge, wherein each closing edge is perpendicular to the plurality of transition edges; transforming each transition polygon into a printing assist feature; and forming a first mask layout or a second mask layout from the printing assist features and the critical features. | 04-12-2012 |
| 20100042967 | MEEF REDUCTION BY ELONGATION OF SQUARE SHAPES - A method that purposely relaxes OPC algorithm constraints to allow post OPC mask shapes to elongate along one direction (particularly lowering the 1-dimensional MEEF in this direction with the result of an effectively overall lowered MEEF) to produce a pattern on wafer that is circular to within an acceptable tolerance. | 02-18-2010 |
| 20090191468 | Contact Level Mask Layouts By Introducing Anisotropic Sub-Resolution Assist Features - This disclosure includes a SRAF layout that minimizes the number of SRAFs required to reliably print contact shapes. A method is provided that reduces the number of necessary SRAF features on a mask, placing at least two elongated SRAF shapes on the mask such that the elongated SRAF shapes extend past at least one edge of a mask shape in at least one direction. | 07-30-2009 |
| 20090146242 | METAL ION TRANSISTOR AND RELATED METHODS - A metal ion transistor and related methods are disclosed. In one embodiment, the metal ion transistor includes a cell positioned in at least one isolation layer, the cell including a metal ion doped low dielectric constant (low-k) dielectric material sealed from each adjacent isolation layer; a first electrode contacting the cell on a first side; a second electrode contacting the cell on a second side; and a third electrode contacting the cell on a third side, wherein each electrode is isolated from each other electrode. | 06-11-2009 |
| 20090146181 | INTEGRATED CIRCUIT SYSTEM EMPLOYING DIFFUSED SOURCE/DRAIN EXTENSIONS - An integrated circuit system that includes: providing a PFET device including a doped epitaxial layer; and forming a source/drain extension by employing an energy source to diffuse a dopant from the doped epitaxial layer. | 06-11-2009 |
| 20090101979 | Methods of Forming Field Effect Transistors Having Stress-Inducing Sidewall Insulating Spacers Thereon and Devices Formed Thereby - Methods of forming integrated circuit devices include forming a field effect transistor having a gate electrode, a sacrificial spacer on a sidewall of the gate electrode and silicided source/drain regions. The sacrificial spacer is used as an implantation mask when forming highly doped portions of the source/drain regions. The sacrificial spacer is then removed from the sidewall of the gate electrode. A stress-inducing electrically insulating layer, which is configured to induce a net tensile stress (for NMOS transistors) or compressive stress (for PMOS transistors) in a channel region of the field effect transistor, is then formed on the sidewall of the gate electrode. | 04-23-2009 |
