Current top-down methods of chip production use electron beam lithography, an expensive process that involves etching silicon into smaller and smaller pieces. Such methods will eventually hit a limit at which further miniaturization would entail extreme expense...
...Case in point: at the Hilton Hawaiian Village, a nine-hectare mega-resort at the western end of Waikiki Beach, a 25-story tower opening in May will house a 3,900-sq-m spa and "wellness center." One of its main attractions: a state-of-the-art Electron Beam Tomography scanner, the first of its kind to be installed in a resort setting. This $2 million machine works with high-resolution ultrasound and other space-age diagnostic tools to detect early signs of heart disease and cancer. For around $8,000 per person, anyone whose stock portfolio hasn...
FULL-BODY SCAN This is the Cadillac of high-tech testing. Using a technology known as electron-beam computed tomography, radiologists take detailed internal pictures from the shoulders to the pelvis. The whole thing takes 10 minutes and provides such information as how much unwanted calcium has collected in your coronary arteries, whether there is an abnormal growth in your liver or colon or whether your bones are showing early signs of osteoporosis. Cost: $500 to $725, little of which your insurer is likely to reimburse...
...whizziest new device, an ultrafast form of computer scanning called electron-beam computer tomography (EBCT), picks up the presence of tiny deposits of calcium in the heart. One study based on the scan showed that patients who build up 20% or more calcium each year have an 18-fold greater chance of suffering a heart attack than those with less calcium in their hearts...
...MOLECULAR AND DOT COMPUTERS Other exotic designs include the molecular computer and the quantum dot computer (which replace the silicon transistor with a single molecule and a single electron, respectively). But these approaches face formidable technical problems, such as mass-producing atomic wires and insulators. No viable prototypes yet exist...
