Multiple sclerosis (MS) is a demyelinating disease of the central nervous system and is the common cause of optic neuritis. Fingolimod, an immunosuppressive agent, is used in MS to prevent acute exacerbations. We report a case of relapsing–remitting MS treated with fingolimod. The patient presented with an acute decrease in vision in the left eye. Eye examination showed clinical macular edema (ME)...
The area of gate metrology in the semiconductor fabrication process is being challenged with stringent thickness and composition control requirements. Control of component thicknesses and compositions of nitrided gate oxides and complex Hi-K film stacks has become a critical requirement for process development and control. Implementation of lab based techniques like XPS, XRF, XRR, SIMS, EXES etc....
In this paper, we investigated a novel and unique, high throughput, inline XPS technique for thin film (<; 100 A) measurements, such as SiON and HfO2. Inline XPS measurement capability was evaluated using four separate techniques; offline SIMS, offline XPS, inline ellipsometry and inline micro X-ray fluorescence (XRF). A Nitrogen sensitivity test determined that the detection limit was on the order...
