A photomask cleaning apparatus includes a photomask receiving stage and a laser supply unit. The photomask receiving stage is configured to receive and retain a photomask in a desired orientation. The photomask has a front face having a pellicle adhesive residue region thereon. The desired orientation is with the front face positioned to allow gravity to move particles on the front face away from the front face without interference from the front face of the photomask. The laser supply unit is configured to generate a laser beam that irradiates a target region on the front face of the photomask to remove a pellicle adhesive residue from the target region. The photomask cleaning apparatus is configured to move the target region on the front face of the photomask to irradiate the entire pellicle adhesive residue region. Methods of using the photomask cleaning apparatus are also provided.

For fabricating an image sensor, an isolation structure is formed to define a first active region of a semiconductor substrate. A first transistor and a second transistor of a unit pixel are formed in the first active region. In addition, a threshold voltage lowering region is formed in a portion of the semiconductor substrate near a portion of the isolation structure abutting the second transistor in the first active region. The threshold voltage lowering region causes the second transistor to have a respective threshold voltage magnitude that is lower than for the first transistor. The threshold voltage lowering region is formed simultaneously with a passivation region in a second active region having a photodiode formed therein.

The present invention provides an LOC package wherein the lead frame is in direct contact with the semiconductor device. The lead frame, which includes openings, is positioned directly on the semiconductor device. An adhesive material is applied in the opening in the lead frame. This adhesive material contacts both the lead frame and the semiconductor device. The lead frame is therefore securely held to the semiconductor device. Wires can then be bonded to contact pads on the semiconductor device and to the lead frame.
