PURPOSE: An image sensor, a manufacturing method thereof, and a device including the same are provided to improve reliability by preventing the deterioration of a saturation level of a sensor array due to moisture absorption. CONSTITUTION: A photoelectric conversion device(120) is formed on a substrate(110). A wiring structure(140) is formed on the substrate and includes an inter metal dielectric(130) and multilayered metal wirings. A cavity(150) passes through the wiring structure by corresponding to the photoelectric conversion device. An anti moisture absorption layer(160) is conformally formed on a cavity of the wiring structure and the upper side of the wiring structure. A light guide unit is formed on the anit moisture absorption layer and includes light transmission materials for filling the cavity. The anti moisture preventing layer are formed on both sidewalls and bottom of the cavity and the upper side of the inter metal dielectric.

A method for manufacturing a semiconductor device is provided to reduce a hardness degree of a photoresist pattern by using the photoresist pattern including a calixarene derivative as an ion implantation mask. An isolation layer(102) is formed on a semiconductor substrate in order to define an active region and a field region. A gate oxide layer is formed on the active region. A conductive layer is formed on the substrate. A silicon nitride layer is formed on the conductive layer. A photoresist layer including a calixarene derivative is formed on the silicon nitride layer.

Abstract:
A method for forming fine patterns of a semiconductor device is provided to store energy in a photoresist layer even if smaller energy is projected than threshold energy, thereby obtaining the desired fine patterns. A method for forming fine patterns of a semiconductor device comprises the steps of: forming a photoresist layer having threshold energy on a semiconductor substrate(101), the threshold energy corresponding to minimum exposure energy to react to the photoresist layer chemically; projecting a first light having a first energy which is lower than the threshold energy to a first region of the photoresist layer to form a preliminary exposure region maintaining the first energy, the preliminary exposure region limiting a non-exposure region; projecting a second light having a second energy which is lower than the threshold energy to a second region in the preliminary exposure region and to the non-exposure region to convert the second region into an exposure region, the sum of the first and second energies the same and higher as/than the threshold energy; and removing the exposure region selectively to form photoresist patterns(110).
