An image sensor includes a first chip including a pixel region, a pad region, and an optical black region interposed between the pixel region and the pad region, and a second chip being in contact with a first surface of the first chip and including circuits for driving the first chip. The first chip includes a first substrate, a device isolation portion disposed in the first substrate and defining unit pixels, an interlayer insulating layer interposed between the first substrate and the second chip, a connection wiring structure disposed in the interlayer insulating layer, and a connection contact plug disposed in the interlayer insulating layer and connecting the connection wiring structure to the device isolation portion in the optical black region. The image sensor further includes a conductive pad disposed in the first chip or the second chip.

Image sensor

An image sensor includes; a photoelectric conversion element disposed on a substrate, a fence structure disposed on the substrate and including a low refractive index layer stacked on a barrier layer, wherein the barrier layer includes at least one metal, and a color filter disposed inwardly lateral with respect to a sidewall of the fence structure, wherein the barrier layer includes an inward lateral protrusion.

Image sensor including fence structure disposed laterally of color filters

Provided is a method of manufacturing a transparent circuit substrate for a touch screen. The method may involve forming an electrode layer on a transparent substrate, stacking a light shielding layer on the transparent substrate such that the light shielding layer is located on an outside of the electrode layer, stacking a mask on the light shielding layer and the electrode layer, forming a conductive layer on the mask, forming connecting lines for connecting the electrode layer and connecting terminals by removing the mask and a portion of the conductive layer, and forming the connecting terminals on the light shielding layer such that the connecting terminals contact the connecting lines.

Method of manufacturing transparent circuit substrate for touch screen

An image sensor includes a photoelectric conversion element in a substrate, a first storage region spaced apart from the photoelectric conversion element in the substrate, a gate on the first storage region, a light shielding layer covering the gate, a dielectric layer disposed between the gate and the light shielding layer and extending onto a top surface of the substrate, an interlayer insulating structure covering the light shielding layer, and a micro-lens overlapping with the photoelectric conversion element on the interlayer insulating structure. The light shielding layer includes a first portion covering a sidewall of the gate, and a second portion on a top surface of the gate. The first portion has a first thickness corresponding to a vertical height from a bottom surface of the first portion to a top surface of the first portion, and the first thickness is greater than a second thickness of the second portion.

Image sensors and methods of fabricating the same

Provided herein is a capacitive-type touch panel. The capacitive-type touch panel may include a first transparent substrate, a first conductive layer positioned on the first transparent substrate, a sensor layer having a second conductive layer spaced from the first conductive layer by a spacer, and a second transparent substrate positioned on the sensor layer. The first conductive layer and the second conductive layer may be transparent.
