Abstract: A method of repairing a light-emitting device capable of performing high quality image display even if pinholes are formed when forming an organic compound layer is provided. Device contamination can be prevented during repair. By applying a reverse bias voltage to an organic light emitting element during fixed periods of time, the electric current flowing in the EL element during application of the reverse bias voltage is reduced. Further, by forming a cathode so as to contain as little as possible of the high mobility ions Li and Na, contamination of the device when the reverse bias is applied can be prevented. It is preferable to use AlMg and MgAg for this type of cathode.

Abstract: A rapid thermal process (RTP) provides steps wherein silicon wafers that are pre-coated with barrier metal films by either in-situ or ex-situ CVD or physical vapor deposition (PVD) are pre-treated, prior to deposition of a Cu film thereon, in a temperature range of between 250 and 550 degrees Celsius in a non-reactive gas such as hydrogen gas (H2), argon (Ar), or helium (He), or in an ambient vacuum. The chamber pressure typically is between 0.1 mTorr and 20 Torr, and the RTP time typically is between 30 to 100 seconds. Performing this rapid thermal process before deposition of the Cu film results in a thin, shiny, densely nucleated, and adhesive Cu film deposited on a variety of barrier metal surfaces. The pre-treatment process eliminates variations in the deposited Cu film caused by Cu precursors and is insensitive to variation in precursor composition, volatility, and other precursor variables.

Abstract: To reduce the edge roll off in a semiconductor wafering process, the wafer (110) is subject to a plasma etch with an edge underetch. The edge underetch is achieved by means of a wafer holder (410) that emits gas towards the wafer (e.g. a gas vortex) to draw the wafer towards the holder's body (460). The plasma impinges on the wafer surface (110.1) opposite to the body. Some of the gas emitted by the holder wraps around the wafer edge and dilutes the etchant near the wafer edge. Consequently, the etch proceeds slower near the edge (the edge is underetched). In some embodiments, the wafer is rotated around an axis (440) passing through the wafer to increase the underetch.
