| Summary: | Digital imaging systems, such as, for example, digital cameras, utilize integrated circuit devices or chips as image capturing devices. An imaging system, such as a camera, uses light to capture an image on a semiconductor-based chip. The chip replaces film in traditional film-based systems. In a digital camera, an image sensor is configured, in its simplest form, to capture a monochrome or color image by way of field effect transistors (FETs), such as complementary metal oxide semiconductor (CMOS) devices or charge coupled devices (CCDs).
A method of forming a microlens including, in one aspect, depositing a substantially non-photo-imageable microlens material over an area of a chip, a portion of which contains an array of photosensitive circuits, and patterning the microlens material over the array of photosensitive circuits to define a microlens over each photosensitive circuit. |
