Abstract
Systems and methods are disclosed for fabricating a device by forming a photosensitive area on a wafer; forming a control circuit adjacent the photosensitive area; and coating the photosensitive area with one or more film layers to form an optical filter. The filter provides a reduced leakage of an undesired wavelength onto the photosensitive area.
Claims20
A method for fabricating a device, comprising:
- forming a photosensitive area on a wafer;
- forming a control circuit adjacent the photosensitive area;
- and
- coating the photosensitive area with one or more film layers to form an optical filter said filter providing a reduced leakage of an undesired wavelength onto the photosensitive area.
1 more element
An integrated circuit (IC) device, comprising:
- a control circuit formed on a wafer;
- a photosensitive area formed adjacent the control circuit;
- and
- a coating deposited above the photosensitive area having one or more film layers forming an optical filter, said filter providing a reduced leakage of an undesired wavelength onto the photosensitive area.
