Wafer-level optics
Encyclopedia
Wafer-level optics enables the design and manufacture of miniaturized optics at the wafer level using advanced semiconductor
-like techniques. The end product is cost effective, miniaturized optics that enable the reduced form factor of camera modules for mobile devices..
The technology is scalable from a single-element CIF/VGA lens to a multi-element mega pixel lens structure, where the lens wafers are precision aligned, bonded together and diced to form multi-element lens stacks. As of 2009 the technology was used in about 10 percent of the mobile phone camera lens market.
Semiconductor
A semiconductor is a material with electrical conductivity due to electron flow intermediate in magnitude between that of a conductor and an insulator. This means a conductivity roughly in the range of 103 to 10−8 siemens per centimeter...
