Electron beam proximity correction method for hierarchical design data

A method for formulating an exposure dose for an electron beam on a resist film for a pattern of geometric shapes which compensates for electron scattering effects utilizing hierarchial design data which is preserved to as great as an extent as possible in the computation of the exposure dose. The exposure dose is corrected for both the forward scatter and backscatter effects of the electron beam in which the design data is modified for interactions of shapes which are affected only over the forward scatter range. In another version of the method, a multiple Gaussian approximation is used where the short term Gaussian terms are treated as the forward scatter terms and the long term Gaussian terms are treated as the back scatter terms.

Efficient high-ampacity bowl-shaped tubular conductors

A high ampacity busbar includes a pair of oppositely facing bowl-shaped conductors, each of whose cross sections resembles half of a hexagon or an open isosceles trapezoid, separated by an air gap in both horizontal and vertical configurations. The air gap increases cooling efficiency by natural convection by exposing more surface area of the conductors directly to the air flow within the electrical distribution equipment cabinet. As a result, the overall temperature of the bus system is reduced. The shaped conductors have smoother transitions presented to the electrical current between the bends of the conductors. These smooth transitions improve current distribution throughout the conductor, reducing skin effects. As a result of improved thermal dissipation and reduced skin effects, the amount of copper needed to maintain the same ampacity is significantly reduced. Magnetic shields can be placed between adjacent busbars, reducing proximity effects.

Method utilizing compensation features in semiconductor processing

A photolithography and etch process sequence includes a photomask having a pattern with compensation features that alleviate patterning variations due to the proximity effect and depth of focus concerns during photolithography. The compensation features may be disposed near isolated or outermost lines of a device pattern. A photoresist pattern is formed to include the compensation features and the pattern etched to form a corresponding etched pattern including the compensation features. After etching, a protection material is formed over the layer and a trim mask is used to form a further photoresist pattern over the protection material. A subsequent etching pattern etches the protection material and removes the compensation features and results in the device lines being formed unaffected by proximity effects. Flare dummies may additionally be added to the mask pattern to increase pattern density and assist in endpoint detection. Flare dummies, like the compensation features, are subsequently removed by a photolithography and etching process sequence.

A method for forming a patterned target layer from a blanket target layer while employing a blanket photoresist layer in conjunction with an exposure method which is susceptible to a proximity effect employs when exposing the blanket photoresist layer to form an exposed blanket photoresist layer a main latent pattern and a second latent pattern adjacent the main latent pattern. Each patterned photoresist layer formed upon developing the main latent pattern is formed of a first linewidth such that not all of a first portion of the blanket target layer formed therebeneath is etched within an isotropic etchant which is employed for etching the blanket target layer to form the patterned target layer. In contrast, each patterned photoresist layer formed upon developing the second latent pattern is formed of a second linewidth such that all of a second portion of the blanket target layer formed therebeneath is etched within the isotropic etchant which is employed for etching the blanket target layer to form the patterned target layer. The method is particularly useful for efficiently forming a photomask while attenuating a proximity effect.

Reduction of Proximity Effects in Field-Effect Transistors with Embedded Silicon-Germanium Source and Drain Regions

An integrated circuit and method of fabricating the same utilizing embedded silicon-germanium (SiGe) source / drain regions, and in which the proximity effect of nearby shallow trench isolation structures is reduced. Embedded SiGe source / drain structures are formed by selective epitaxy into recesses etched into the semiconductor surface, on either side of each gate electrode. The SiGe structures overfill the recesses by at least about 30% of the depth of the recesses, as measured from the interface between the channel region and the overlying gate dielectric at the edge of the gate electrode. This overfill has been observed to reduce proximity effects of nearby shallow trench isolation structures on nearby transistors. Additional reduction in the proximity effect can be obtained by ensuring sufficient spacing between the edge of the gate electrode and a parallel edge of the nearest shallow trench isolation structure.
