Abstract:
An apparatus for processing the surface of a wafer having a copper pattern using plasma is provided to reduce impurity particles and damage to a chamber and shorten an interval of process time by reducing thermal budget to a wafer and by performing a series of processes for forming a capping layer for protecting a copper pattern and cleaning a process chamber. A wafer(W) is processed in a process chamber(210). Gas is injected to the process chamber by a gas guide pipe(220). The gas introduced from the gas guide pipe is uniformly sprayed to the inside of the process chamber by a shower head(230). A heating block(240) on which a wafer is to be placed is installed in the process chamber. A plasma generating module(270) generates NH3 plasma outside the process chamber. The NH3 plasma generated from the plasma generating module is injected into the process chamber by a plasma guide pipe. The gas in the process chamber is exhausted to the outside by an exhaust pipe(250). The exhaust pipe is opened/shut by a valve(260). The plasma generating module can generate NF3 plasma additionally.

An imaging device and its manufacturing method are provided to improve optical sensitivity by using a light opening unit pattern for collecting a light before being incident into a photo diode. Semiconductor devices including an optical device is formed on a substrate(100). A lower dielectric(130) is formed on the substrate and has an optical path groove(255) on an upper portion of the optical device. The optical path groove has a lower surface whose shape is convex upwardly to increase optical sensitivity of the optical device. An interlayer dielectric structure is formed on the lower dielectric to be extended to the lower optical path groove. A light opening unit(254) is formed on the interlayer dielectric structure. A light opening unit pattern(256) is formed to gap-fill the optical path groove and the light opening unit. A micro lens(310) is located on an upper portion of the light opening unit on the interlayer dielectric structure.

Methods of manufacturing a semiconductor device are provided to improve the step coverage of a seed layer by forming a slant portion made of residues of an etch stop layer in a bottom of a connection hole. An etch stop layer(140) and an interlayer dielectric(150) are sequentially formed on a semiconductor substrate(100) with a lower conductive layer. A via hole(155c) for exposing partially the etch stop layer to the outside is formed in the interlayer dielectric. A portion with slant(s) is formed at lower sidewalls of the connection hole by etching selectively the exposed etch stop layer.

PURPOSE: A method for forming a metal pattern of a semiconductor device is provided to be capable of stably forming an upper pattern on a lower via part. CONSTITUTION: The first insulating layer(120) is formed at the upper portion of a semiconductor substrate(100). The first via holes are formed by carrying out a photo etching process at the first insulating layer using the first photo mask. The first via parts(130a,130b) are formed by filling the first metal at the first via holes. An etch stop layer(140) and the second insulating layer(150) are sequentially formed at the upper portion of the resultant structure. The second via holes are then formed for exposing the upper surfaces of the first via parts. A metal layer is formed at the upper portion of the resultant structure for filling the second via holes. A metal pattern is then formed by selectively patterning the metal layer.

CONSTITUTION: The first metal line(110a) and the second metal line(110b) are formed on a substrate(100). A diffusion barrier pattern for exposing the first metal line is formed on the substrate in order to prevent the damage of the second metal line. A dielectric layer is formed on the diffusion barrier pattern and the second metal line. A top electrode layer is formed on the dielectric layer. The first photoresist pattern is formed on the top electrode layer in order to define a capacitor region. A top electrode(140a) of a capacitor is formed by over-etching the exposed top electrode layer.
