A method of generating an IC layout diagram includes receiving an IC layout diagram including a gate region and a gate via, the gate via being positioned at a location within an active region and along a width of the gate region extending across the active region, receiving a first gate resistance value of the gate region, retrieving a second gate resistance value from a resistance value reference based on the location and the width, using the first and second resistance values to determine that the IC layout diagram does not comply with a design specification, and based on the non-compliance with the design specification, modifying the IC layout diagram.

Integrated circuit layout generation method

A method of generating an IC layout diagram includes receiving a first gate resistance value of a gate region in an IC layout diagram, the first gate resistance value corresponding to a location of a gate via positioned within an active region and along a width of the gate region extending across the active region, determining a second gate resistance value based on the location and the width, using the first and second resistance values to determine that the IC layout diagram does not comply with a design specification, and based on the non-compliance with the design specification, modifying the IC layout diagram.

A method of generating a netlist of an IC device includes receiving gate region information of the IC device. The gate region information includes a width of the gate region, the width extending at least from a first edge of an active region to a second edge of the active region, a location of a gate via positioned within the active region and along the width, and a first gate resistance value corresponding to the gate region. The method includes determining a second gate resistance value based on the location and the width, and modifying the netlist based on the second gate resistance value.

Integrated circuit layout generation method and system

A method of generating a netlist of an IC device includes extracting dimensions of a gate region of the IC device, the dimensions including a width of the gate region, the width extending at least from a first edge of an active region to a second edge of the active region, and a distance from a first end of the width to a gate via positioned along the width. A first gate resistance value corresponding to the gate region is received, a second gate resistance value is determined based on the distance and the width, and the netlist is updated based on the first and second gate resistance values.

This application relates to a process to suppress the impurity diffusion through gate oxide on silicided amorphous-Si gate structures that utilize the silicide layers as the implantation barrier to minimize the impurity diffusion by reducing the projectile range and implant-induced defects, resulting in smaller flat-band voltage(V,) shift and better characteristics of the breakdown field(E,) and charge to breakdown(Q,). In addition, the amorphous-Si underlying layer is simultaneously kept during the formation of a low-temperature self-aligned silicide (SAD) process to further retard the impurity diffusion. Hence, the usage of such bilayered silicide/amorphous-Si films could effectively retard the impurity diffusion, by combining both effects of the amorphous-Si layer and the silicide process or inducing other undesirable effects such as the increase of gate sheet resistance.
