According to the invention, the surface of the amorphous silicon is enhanced with 10-15% hydrophobic element, however in other embodiments, this composition may be adjusted as needed. In any case, however, the invention herein includes maintaining an etch selectivity of the bulk amorphous silicon hardmask. |

Post growth heteroepitaxial layer separation for defect reduction in heteroepitaxial films
A method for reducing crystalline defects in a semiconductor structure is presented. The method includes epitaxially growing a first crystalline material over a crystalline substrate, epitaxially growing a second crystalline material over the first crystalline material, and patterning and removing portions of the second crystalline material to form openings. The method further includes converting the first crystalline material into a non-crystalline material, depositing a thermally stable material in the openings, depositing a capping layer over the second crystalline material and the thermally stable material to form a substantially enclosed semiconductor structure, and annealing the substantially enclosed semiconductor structure. |

Parallel mass analysis
A system and method of mass spectrometry is provided. Ions from an ion source are stored in a first ion storage device and in a second ion storage device. Ions are ejected from the first ion storage device to a first mass analysis device during a first ejection time period, for analysis during a first analysis time period. Ions are ejected from the second ion storage device to a second mass analysis device during a second ejection time period. The ion storage devices are connected in series such that an ion transport aperture of the first ion storage device is in communication with an ion transport aperture of the second ion storage device. The first analysis time period and the second ejection time period at least partly overlap. |

Method of producing a mass spectrum
A method of producing a mass spectrum from a time-varying transient signal detected in a mass spectrometer, the method comprising: performing a Fourier transform of the transient signal to produce a first set of complex amplitudes wherein each of the complex amplitudes corresponds to a respective frequency of a first set of frequencies; generating a second set of complex amplitudes, wherein each of the complex amplitudes corresponds to a respective frequency of a second set of frequencies with a minimum spacing less than the inverse of the duration of the transient signal; optimizing the second set of complex amplitudes to produce an improved second set; generating a mass spectrum from at least some of the improved second set of complex amplitudes; wherein optimizing the second set of complex amplitudes to produce an improved second set of complex amplitudes is based on an objective function subject to some phase constraints. |

Substrate treating apparatus
The inventive concepts provide a substrate treating apparatus. The apparatus includes a process chamber, a substrate support unit, a gas supply unit, a microwave applying unit, an antenna plate, a slow-wave plate, a dielectric plate, and an exhaust baffle, and a liner. The liner includes a body having a ring shape facing an inner sidewall of the process chamber, and a flange extending from the body into a wall portion of the process chamber. The flange prevents an electric field of a microwave and a process gas from being provided into a gap between the process chamber and the body. Thus, it is possible to inhibit particles from being generated by damage of the inner sidewall of the process chamber by plasma, and drift distances of the particles can be reduced to inhibit the particles from reaching a substrate. |
