Title          
FASTCAM SA1 : DigInfo 
   
 
Abstract    
DigInfo - http://movie.diginfo.tv Photron, who produces high-speed video camera solutions, has just released its FASTCAM SA1. This high-speed camera can film 1,024x1,024 full-frame pixels at 5,400 frame/s. Segmented frame is available as well: 1,024x512 pixels at 10,000 frame/s; 128x128 pixels at 90,000 frame/s; and 128x32 pixels at the maximum speed of 150,000 frame/s. The camera comes with a 2-microsecond electronic shutter, an embedded CMOS sensor for color and monochrome shoots, and a collection of presets so as to not to initially overwhelm the user. It comes with 8GB of memory (easily expandable to 16GB) which can be subdivided into folders so you can organize your photos more effectively.

Title          
Photolithography 
   
 
Abstract    
A video explaining photolithography. It is part of the Nanoscale exhibition. Filmed at the Cornell Nanoscale Facility. Produced by Brant Penman. Photolithography (or "optical lithography") is a process used in microfabrication to selectively remove parts of a thin film or the bulk of a substrate. It uses light to transfer a geometric pattern from a photo mask to a light-sensitive chemical photo resist, or simply "resist," on the substrate. A series of chemical treatments then engraves the exposure pattern into the material underneath the photo resist. In complex integrated circuits, for example a modern CMOS, a wafer will go through the photolithographic cycle up to 50 times. Photolithography shares some fundamental principles with photography in that, the pattern in the etching resist is created by exposing it to light, either using a projected image or an optical mask. This procedure is comparable to a high precision version of the method used to make printed circuit boards. Subsequent stages in the process have more in common with etching than to lithographic printing. It is used because it affords exact control over the shape and size of the objects it creates, and because it can create patterns over an entire surface si...
