We simulate sodium chloride currents through the gramicidin A channel using the spectral element method to solve the three-dimensional Poisson–Nernst–Planck (PNP) equations. Using the spectral element method, we are able to simulate the entire ch

We predict the sodium current through an ion channel of known structuregramicidin A (gA)using an electrostatic model of the ion channel and an electrodiffusion model of ion movement. We use three-dimensional (3D) spectral elements to represent the ch

Recent advances in computational microelectronics have made it possible to compute the images of very large masks. Images of entire masks require many gigabytes of storage. It is therefore desirable to make storage requirements as small as possible.

Photolithography for the formerly "non-critical" implant blocking layers is becoming more challenging as edge placement control budgets for junction definition shrink with each node. In addition to the traditional proximity effects associated with th

Critical aspect ratio induced pattern collapse has been a concern for lithography process engineers since before the 180 nm node. This has driven a steady reduction in photoresist thickness, as well as accelerated the introduction of hard mask materi

A complete numerical simulation package for submicron photolithography is described in depth. Four of the computational steps are analyzed: aerial image generation, exposure, postexposure bake, and dissolution. An application to bar printing over a M

For advance semiconductor manufacturing, patterning contact and via mask layers continue to be major challenge. As a result, RET's beyond the current standard 6% attPSM technology are being pursued with a goal of reducing the k 1 for hole patterning

With immersion and hyper numerical aperture (NA>1) optics apply to the ITRS 2003/4 roadmap scenario (Figure 1); it is very clear that the IC manufacturing has already stepped into the final frontier of optical lithography. Today’s advanced lithogra

Scattering Bars (SB) OPC, together with optimized illumination, is no doubt one of the critical enablers for low k 1 lithography manufacturing. The manufacturing implementation of SB so far has been mainly based on rule-based approach. While this has
