摘要： An oxide etching recipe including a heavy hydrogen-free fluorocarbon having F/C ratios less than 2, preferably C4F6, an oxygen-containing gas such as O2 or CO, a lighter fluorocarbon or hydrofluorocarbon, and a noble diluent gas such as Ar or Xe. The amounts of the first three gases are chosen such that the ratio (F—H)/(C—O) is at least 1.5 and no more than 2. Alternatively, the gas mixture may include the heavy fluorocarbon, carbon tetrafluoride, and the diluent with the ratio of the first two chosen such the ratio F/C is between 1.5 and 2.

摘要： A method of etching silicon oxide with high selectivity to a photoresist mask and to a silicon-containing substrate comprising exposing the silicon oxide to a plasma of a precursor etch gas of a fluorocarbon and an organic silane containing at least one organic group. When at least about 10% by weight of the silane is present in the etch gas, the selectivity between the silicon oxide and the photoresist mask layer, and between the silicon oxide and the silicon-containing substrate, increases markedly. High aspect ratio, submicron size openings can be etched.

摘要： A magnetron plasma etching apparatus comprises a chamber and a mount for supporting a substrate. A high-potential electrode connected to an RF power source is connected to the mount, and a low-potential electrode which is grounded is connected to the chamber. A rotary magnet is provided above the chamber, thereby generating a rotary magnetic field intersecting at right angles an electric field generated by both electrodes. An end-point detecting member for detecting an end-point of etching of the substrate is provided at the side of the chamber. The end-point detecting member collects mainly the light at a region near the rotation center of the magnetic field. That light component of a spectrum, which varies greatly with the progress of the etching, is extracted from the collected light, and the intensity of the light of this spectrum is converted to a first electric signal. The intensity of the collected light is converted to a second electric signal. The end-point detecting means calculates a ratio of the first and second electric signals, and the end-point of the etching is detected on the basis of the ratio.

摘要： A method for fabricating a semiconductor mask is described. A semiconductor stack having a sacrificial mask comprised of a series of lines is first provided. A spacer mask having spacer lines adjacent to the sidewalls of the series of lines of the sacrificial mask is then formed. The spacer mask also has interposed lines between the spacer lines. Finally, the sacrificial mask is removed to provide only the spacer mask. The spacer mask having interposed lines triples the frequency of the series of lines of the sacrificial mask.
