Abstract
A camera module for mobile device is reduced in size and production cost. CCDs, which are photoelectronic transducers, are formed in a surface of a semiconductor chip composing an image sensor, and an IR filter is bonded with an adhesive to cover the surface of the semiconductor chip. The IR filter has a filtering function in addition to a function to support the semiconductor chip. The IR filter is obtained by vacuum deposition of metal on a glass material or incorporating copper particles into a glass material, and implements both filtering function and chip-supporting function.
Claims7
A camera module comprising:
- an image sensor chip comprising a semiconductor chip having a photoelectronic transducer formed on a surface of the semiconductor chip and a filter portion disposed on the photoelectronic transducer so as to block light incident on the filter portion at a predetermined range of wavelength;
- and
- a lens disposed above the image sensor chip.
