摘要:
The techniques and technologies described herein relate to the automatic creation of photoresist masks for stress liners used with semiconductor based transistor devices. The stress liner masks are generated with automated design tools that leverage layout data corresponding to features, devices, and structures on the wafer. A resulting stress liner mask (and wafers fabricated using the stress liner mask) defines a stress liner coverage area that extends beyond the boundary of the transistor area and into a stress insensitive area of the wafer. The extended stress liner further enhances performance of the respective transistor by providing additional compressive/tensile stress.

A first bias charge is provided to first bias region at a first level of an electronic device, the first bias region directly underlying a first transistor having a channel region at a second level that is electrically isolated from the first bias region. A voltage threshold of the first transistor is based upon the first bias charge. A second bias charge is provided to second bias region at the first level of an electronic device, the second bias region directly underlying a second transistor having a channel region at a second level that is electrically isolated from the first bias region. A voltage threshold of the second transistor is based upon the second bias charge.

The halo implant technique described herein employs a halo implant mask that creates a halo implant shadowing effect during halo dopant bombardment. A first transistor device structure and a second transistor device structure are formed on a wafer such that they are orthogonally oriented to each other. A common halo implant mask is created with features that prevent halo implantation of the diffusion region of the second transistor device structure during halo implantation of the diffusion region of the first transistor device structure, and with features that prevent halo implantation of the diffusion region of the first transistor device structure during halo implantation of the diffusion region of the second transistor device structure. The orthogonal orientation of the transistor device structures and the pattern of the halo implant mask obviates the need to create multiple implant masks to achieve different threshold voltages for the transistor device structures.

A stress-enhanced semiconductor device is provided which includes a substrate having an inactive region and an active region, a first-type stress layer overlying at least a portion of the active region, and a second-type stress layer. The active region includes a first lateral edge which defines a first width of the active region, and a second lateral edge which defines a second width of the active region. The second-type stress layer is disposed adjacent the second lateral edge of the active region.

The present invention generates model scenarios of semiconductor chip design and uses interpolation and Monte Carlo, with random number generation inputs, techniques to iteratively assess the models for a more comprehensive and accurate assessment of design space, and evaluation under projected manufacturing conditions. This evaluation information is then incorporated into design rules in order to improve yield.
