| 20080245674 | SYSTEM AND METHOD FOR OBTAINING ANISOTROPIC ETCHING OF PATTERNED SUBSTRATES - Systems and methods for etching topographic features in non-crystalline or metallic substrates are provided. A protective material is placed and patterned on a surface of the substrate to define exposed and protected regions of the substrate for etching in a liquid etchant having etching rates that are thermally activated. A nonuniform temperature profile is imposed on the substrate so that the temperatures and hence the etching rates at surfaces in the exposed regions are higher than those in the protected regions. Arrangements for imposing the nonuniform temperature profile include heating designated portions of the substrate with light radiation. Alternatively, the non-uniform temperature profile is developed as etching progresses by passing current pulses through the substrate in a manner that causes geometrically non-uniform heating of the substrate. | 10-09-2008 |
| 20080264801 | Systems And Methods For Monitoring Plating And Etching Baths - Methods and systems for monitoring electrolyte bath fluids are provided. The electrolyte bath fluids can be electroplating, electroless plating or etching solutions.
