In this study, the Taguchi method was used to optimize the effect of HALO structure or halo implant variations on threshold voltage (VTH) and leakage current (ILeak) in 45nm p-type Metal Oxide Semiconductor Field Effect Transistors (MOSFETs) device. Besides halo implant dose, the other process parameters which used were Source/Drain (S/D) implant dose, oxide growth temperature and silicide anne...

The simulation experiment is performed to characterize the impact of process level fluctuations on the circuit performance variation for the 0.1µm CMOS technology. The 0.1µm NMOS and PMOS transistors are optimized using four different ion implantation steps namely super steep retrograde channel (SSRC) implant, deep s/d implant, shallow s/d extension implant and halo implant. We demonstrate that...

Ultra-Shallow Junction formation is one of the most challenging areas of semiconductor processing to monitor. Most of the dopant characterization techniques, both electrical and optical, are primarily designed to monitor only one step of doping process: they can be used either to monitor implant induced defect density or to measure activated doping. The presented Surface Photo-Voltage (SPV) bas...

METHOD: Halo radius was measured using a vision monitor (MonCv3) with low-luminance optotypes in 39 eyes that had cataract surgery and the bilateral implant of an Acrysof Restor SN6AD1 multifocal IOL or Acrysof IQ monofocal IOL 6 to 9 months previously. The visual angle subtended by the disk halo radius was calculated in minutes of arc (arcmin). Patient complaints of halo disturbances were reco...

Process, device, and mixed-mode (device/circuit) simulation-based approach is presented for 0.1m gate length CMOS technology optimization and sensitivity analysis. The disposable spacer-based 0.1m NMOS and PMOS transistors with excellent short channel characteristics are designed using process and device simulations. The implant-dose sensitivity of the device parameters around the nominal value...

PURPOSE To compare, as a function of pupil size, the through-focus performance and halo features of four diffractive intraocular lenses (IOLs). METHODS Three diffractive bifocal IOLs (ReSTOR +2.5 D SV25T0, Tecnis +2.75 D ZKB00, and AT LISA +3.75 D 809M) and a diffractive trifocal IOL (AT LISA tri +3.33 D, +1.66 D 839MP) were tested in vitro in a modified International Organization for Standar...

BACKGROUND Negative news media reports regarding potential health hazards of implanted medical devices and pharmaceuticals can lead to a 'negative halo effect,' a phenomenon whereby judgments about a product or product type can be unconsciously altered even though the scientific support is tenuous. To determine how a 'negative halo effect' may impact the rates of use and/or explantation of medi...

Introduction The goal of posterior spinal fusion in neuromuscular scoliosis is to obtain a balanced trunk as well as accommodative, pressurefree seating on a level pelvis. Development of pelvic obliquity or involvement of the pelvis in the scoliotic curve can cause difficulties with seating, costopelvic impingement, and worsening pulmonary function, ultimately leading to difficulty with caregiv...

introduction: the objective of this study was to evaluate the relationship between spermiogenic defects such as protamine deficiency, and acrosomal integrity with fertilization and pregnancy rate in ivf patients. material and methods: density, motility and morpology of semen samples from 70 infertile couples undergoing ivf at isfahan fertility and infertility center were analyzed according to w...
