Abstract: An amplifier for improving an electrostatic discharge (ESD) characteristic includes an operational amplifier, a first resistor circuit, a first fuse box, a second resistor circuit, and a second fuse box. The operational amplifier includes a first input terminal receiving a first input signal, a second input terminal receiving a second input signal, and an output terminal outputting an output signal. The first resistor circuit is connected between the second input terminal and a first node to prevent ESD from being input to the second input terminal. The first fuse box is connected between the first node and the output terminal of the operational amplifier. The second resistor circuit is connected between the second input terminal and a second node to prevent ESD from being input to the second input terminal. The second fuse box is connected between the second node and a terminal for receiving a ground voltage.

Abstract: An alignment mark on a substrate includes a first pattern and a second pattern. The first pattern has a substantially planar upper surface by which parallel light is specularly reflected. The second pattern forms an interface with the first pattern and has a plurality of fine patterns. Parallel light is irregularly reflected by the second pattern.

Abstract: The image senor includes a plurality of row lines and a plurality of column lines crossing the plurality of row lines. A pixel is formed at respective crossings of the row and column lines. Each pixel generates a charge based on light incident thereon and selectively transfers the charge to an associated column line based on a signal received from an associated row line. Each column line has a column driver circuit associated therewith. The column driver circuit is configured to generate an output voltage based on the charge on the associated column line.
