Wafer sawed into separate chips after fabrication. 0000000876 00000 n X-Ray Photolithography is a process which uses X-rays to transfer a geometric pattern from a mask to the resist on the substrate. An antireflective or anti-reflection (AR) coating is a type of optical coating applied to the surface of lenses and other optical elements to reduce reflection.In typical imaging systems, this improves the efficiency since less light is lost due to reflection.

Photolithography Photolithography uses light (UV, deep-UV, extreme-UV or X-ray) to expose a layer of radiation-sensitive polymer (photoresist) through a mask. In the photolithography process a light source is typically used to transfer an image from a patterned mask to a photosensitive layer (photoresist or resist) on a substrate or another thin film. • To create a device such as a transistor, layers of thin films have to be patterned, etched and coated. Photolithography • Photo-litho-graphy: latin: light-stone-writing • Photolithography is an optical means for transferring patterns onto a substrate. In your view, how should one define a strategy for a technology driven company?

Wafer sawed into separate chips after fabrication. 0000000876 00000 n X-Ray Photolithography is a process which uses X-rays to transfer a geometric pattern from a mask to the resist on the substrate. An antireflective or anti-reflection (AR) coating is a type of optical coating applied to the surface of lenses and other optical elements to reduce reflection.In typical imaging systems, this improves the efficiency since less light is lost due to reflection.
