摘要： A process chamber used in the manufacture of a semiconductor device for etching a material layer on a semiconductor wafer includes an electrostatic chuck for holding the semiconductor wafer, and an annular edge ring which surrounds the side of the semiconductor wafer on the electrostatic chuck to prevent the semiconductor wafer from departing from its original position. The annular edge ring has a first side which faces the side of the semiconductor wafer and contacts firmly with the side of the semiconductor wafer.

摘要： A dielectric window of a dry etching apparatus for manufacturing semiconductor devices is shaped so that areas of high density plasma in the etching apparatus correspond to portions of the dielectric window further away from the wafer and areas of lower density plasma correspond to portions of the dielectric window closer to the wafer. For example, the dielectric window may be curve inwards at its center in a concave-shape.

摘要： A conditioning disk and a conditioner for a chemical mechanical polishing (CMP) pad, and a method of fabricating, reworking, and cleaning the conditioning disk, are utilized to improve conditioning efficiency, and to reduce production expenses. The conditioning disk for a CMP pad is divided into regions defined by a size difference of abrasive grains formed on the body surface in each region of the conditioning disk. The method of fabricating the conditioning disk is performed by forming adhesive films for attaching the abrasive grains onto the body surface multiple times. In addition, a used conditioning disk may be reworked by detaching the abrasive grains from the body, and attaching new abrasive grains. A used conditioning disk can also be cleaned of by-products of the conditioning process by a cleaning method using a HF solution or BOE (buffered oxide etch) solution.

摘要： There are provided an apparatus and method for testing semiconductor memory devices, in which the frequencies of test pattern signals can be selectively changed. The test apparatus includes a main tester, an input frequency converter, and an output frequency converter. The main tester generates first input test signals with a first frequency, a first program control signal, and a second program control signal, receives first output test pattern signals with the first frequency, and determines an operating performance of a semiconductor memory device. The input frequency converter converts the first input test pattern signals into second input test pattern signals with a second frequency in response to the first program control signal, and applies the second input test pattern signals to the semiconductor memory device. The output frequency converter converts the second output test pattern signals with the second frequency received from the semiconductor memory device into the first output test pattern signals in response to the second program control signal and outputs the first output test pattern signals. The test apparatus and method can test semiconductor memory devices with a high operating frequency by selectively changing the frequencies of test pattern signals.

摘要： A plasma process apparatus having a plasma chamber with in situ monitoring, a monitoring method, and a method for in situ cleaning a plasma chamber. The apparatus includes a sampling manifold which induces flow of a sample gas from a plasma chamber through the manifold. A gas analyzer analyzes the sample gas flowing through the sampling manifold. The in situ monitoring method monitors an initial gas to establish background levels, and bakes the apparatus to reduce contaminants, if necessary. The monitoring method then monitors a process reaction and, after unloading a wafer and discharging a waste gas, monitors an in situ cleaning reaction. Monitoring involves inducing flow of a gas from the plasma chamber through the sampling manifold, and then analyzing the gas in the manifold with a gas analyzer. The cleaning method includes using a mixture of sulfur hexafluoride and chlorine to clean the plasma chamber after etching a polysilicon layer.
