Image sensing device having protection pattern on the microlens, camera module, and method of forming the same |
摘要 |
An image sensing device having a protection pattern formed on microlenses is provided. The device includes a plurality of photodiodes provided in a semiconductor substrate. An insulating layer having a substantially flat top surface is disposed on the photodiodes. A plurality of microlenses are provided on the insulating layer and disposed over the photodiodes. The microlenses are covered with a protection pattern. The protection pattern can be formed of an oxide-based photosensitive polymer layer or a nitride-based photosensitive polymer layer, as examples. The protection pattern can have a substantially flat top surface. |
