摘要:
A wafer handling system with apparatus for transporting wafers between semiconductor fabrication tools. In one embodiment, the apparatus is a loadport bridge mechanism including an enclosure having first and second mounting ends, a docking port at each end configured and dimensioned to interface with a loadport of a semiconductor tool, and at least one wafer transport robot operable to transport a wafer between the docking ports. The wafer transport robot hands off or receives a wafer to/from a tool robot at the loadports of a first and second tool. The bridge mechanism allows one or more wafers to be transferred between loadports of different tools on an individual basis without reliance on the FAB's automated material handling system (AMHS) for bulk wafer transport inside a wafer carrier such as a FOUP or others.

A system and method of controlling a semiconductor wafer fabrication process. The method includes positioning a semiconductor wafer on a wafer support assembly in a wafer processing module. A signal is transmitted from a signal emitter positioned at a predetermined transmission angle relative to an axis normal to the wafer support assembly to check leveling of the wafer in the module, so that the signal is reflected from the wafer. The embodiment includes monitoring for the reflected signal at a predetermined reflectance angle relative to the axis normal to the wafer support assembly at a signal receiver. A warning indication is generated if the reflected signal is not received at the signal receiver.

An etching method comprises etching an oxide layer with a first dc bias of a plasma chamber, removing a photoresist layer with a second dc bias of the plasma chamber and etching through a liner film with a third dc bias of the plasma chamber. In order to reduce the copper deposition on the wall of the plasma chamber, the third dc bias is set to be less than the first and second dc bias.

The technology relates to a damascene word line for a three dimensional array of nonvolatile memory cells. Conductive lines such as silicon are formed over stacked nonvolatile memory structures. Word line trenches separate neighboring ones of the silicon lines. The silicon lines separated by the word line trenches are oxidized, making insulating surfaces in the word line trenches. Word lines are made in the word line trenches.
