Photographic production of integrated circuits
Numéro d’image : 11894746
| Microchip manufacture. Technician in a clean room with photographic equipment used for manufacturing integrated circuits or microchips. Wafers (held by the technician) of a semiconductor,such as silicon,are coated with a special material called photoresist. The photoresist becomes insoluble after being exposed to light. The wafers are exposed to a light source which is covered by a pattern (mask) which blocks some of the light. Unexposed areas of photoresist are then washed off and the exposed areas are treated (etched) to give them certain electrical properties. The process may be repeated several times with different masks to produce the complete microchip design | |
