Abstract: An integrated circuit (IC) device includes a line structure including a conductive line formed on a substrate and an insulation capping pattern that covers the conductive line; an insulation spacer covering a sidewall of the line structure; a conductive plug spaced apart from the conductive line in a first horizontal direction with the insulation spacer between the conductive plug and the conductive line; a conductive landing pad arranged on the conductive plug to vertically overlap the conductive plug; and a capping layer including a first portion between the conductive landing pad and the insulation capping pattern, wherein the first portion of the capping layer has a shape in which a width in the first horizontal direction gradually increases as a distance from the substrate increases between the conductive landing pad and the insulation capping pattern.

Abstract: A projector includes a light source that emits a light beam, an illumination lens unit, a display device, a projection lens unit, a field lens, and a reflection member. The illumination lens unit shapes and focuses the light beam into an illumination light beam. The display device modulates the illumination light beam and forms an image. The projection lens unit projects the image on a screen. The field lens has a positive refractive power for focusing the illumination light beam on the display device, a first lens surface on which the illumination light beam is incident, and a second lens surface on which the image formed by the display device is incident. The reflection member changes an illumination light beam path into a direction of the field lens. The first lens surface reflects a portion of the illumination light beam into a path that avoids the projection lens unit.
