Abstract: A post dry etching process for restoring wafers damaged by dry etching such as RIE, comprising the steps of removing any dry etch residue layer from the etched portions of the wafer and forming an oxide on those etched portions; rapid thermal annealing the wafer to drive the oxygen from the oxide layer down into the wafer by a small amount, to getter impurities to this oxide layer, and to restore crystallinity below the oxide layer; and removing the oxide layer via an HF bath or a low powder dry etch process.

Abstract: A recirculating high velocity hot air sterilization device includes a housing having a chamber therein. A corrugated, perforated jet curtain plate is disposed within the chamber and partially defines an air supply plenum positioned outwardly of the chamber, the plenum having an electric heating element operatively positioned therein. Spaced apart from the jet curtain plate within the chamber is a nonperforated deflector plate which extends parallel to the jet curtain plate and may be of a flat or corrugated configuration. A blower is connected to the housing and creates therein a recirculating flow of heated air which sequentially flows into the air supply plenum across the heating element, outwardly in a forward direction through the perforations in the jet curtain plate and into the housing chamber, back into the blower, and then into the air supply plenum.

Abstract: An etching method for etching a masked silicon substrate in a vessel by introducing into the vessel an etching gas containing a gaseous chloride of silicon and a nitrogen-containing gas and converting the etching gas introduced in the vessel into a plasma. Ions and radicals are formed from the etching gas under plasma conditions, the ions impinging against the substrate in a sputtering action, and the radicals acting on the substrate to produce a volatile substance. The sputtering action and the volatile substances produce even etched surfaces without surface defects and simultaneously prevent the formation of a white powder, thus avoiding unetched or insufficiently etched portions and portions appearing to be black. In addition, this method makes it possible to realize superior anisotropism in the etching, while increasing the speed and selectivity of etching.

Abstract: A method for determining the extent of polymerization of a polymer system consisting of adding a fluorescent label, the label having a reactivity similar to the reactivity of the curing agent, to the polymer system and measuring the fluorescence intensity proportional to cure species concentration during polymerization. The fluorescence intensity of the label exhibits sensitive changes throughout the polymerization process, allowing one to follow cure reactions in a quantitive way by measuring fluorescence, especially in the latter stages of cure. The cure species composition, reactivity ratio, activation energy and weight-average molecular weight can also be determined by adding a label and measuring the UV-VIS spectra in addition to the fluorescence intensity.

Abstract: A method for forming articles which include silica-containing glass bodies, as well as the resulting articles, are disclosed. In accordance with the method, silica-containing gel particles are fused to form a glass body. In contrast to previous such methods, these particles are formed by mechanically, substantially uniformly subdividing either a substantially cohesive gel body, or an ungelled or partially gelled sol capable of yielding a substantially cohesive gel body, to form substantially uniformly sized, wet gel particles. Significantly, only substantially cohesive gel bodies which are also substantially elastic are useful in the invention, i.e., mechanical subdivision of non-elastic gel bodies results in these bodies undergoing plastic flow to yield non-particulate, pasty masses.

Abstract: A process for manufacturing a pressure transducer of a pressure sensor is disclosed. Initially, a capacitive pressure transducer is formed by bonding a silicon diaphragm to a glass base such that the transducer produces different capacitances in response to different diaphragm deflections provided in response to sensed pressures. The sensitivity of the capacitive pressure transducer is adjusted by etching the silicon diaphragm while it is bonded to the base substrate in accordance with capacitance values of the transducer which were previously obtained at various predetermined pressures. In this manner, the thickness of the silicon diaphragm is selectively reduced to obtain an accurate desired sensitivity for the transducer and handling of very thin silicon diaphragms prior to their assembly to associated transducer bases is eliminated.

Abstract: A first metal film is formed on the major surface of a semiconductor substrate and a thin film which is at least equal in thickness to a second metal film is formed on the first metal film. These films are patterned to provide a two-layer film pattern of a prescribed configuration, and a resist film is coated on the major surface of the semiconductor substrate including the two-layer film pattern. The surface of the resist film is partially removed to expose a thin film pattern serving as an upper layer of the two-layer film pattern, and only the thin film pattern is removed. A second metal film is evaporated over the entire surface of the resist film including the first metal film pattern exposed in the preceding step and thereafter the resist film is removed with the second metal film formed on the same, to form the two-layer metal film pattern by the first metal film pattern and the second metal film pattern.
