    摘要: A method for increasing an electrical resistance of a resistor that is within a semiconductor structure. A fraction of a surface layer of the resistor is oxidized with oxygen particles. In an embodiment, the fraction of the surface layer is heated by a beam of particles, such that the semiconductor structure is within a chamber that includes the oxygen particles as gaseous oxygen-comprising molecules. In an embodiment, the semiconductor structure is immersed in a chemical solution which includes the oxygen particles, wherein the oxygen particles includes oxygen-comprising liquid molecules, oxygen ions, or an oxygen-comprising gas dissolved in the chemical solution under pressurization. In an embodiment, the resistor is tested to determine whether the electrical resistance of the resistor after being oxidized with the oxygen particles is within a tolerance of a predetermined target resistance.

    摘要: An etch apparatus. The etch apparatus includes a tank coupled to a recirculating path that includes a dissolver. The dissolver includes a porous carbon matrix filter coated with silicon nitride. An etchant from the tank circulates through the recirculating path and performs a selective etching of a structure in the tank in contact with the etchant. The structure includes silicon nitride on a pad layer that includes silicon dioxide. The selective etching is characterized by the silicon nitride on the pad layer being selectively etched by the etchant relative to an etching by the etchant of the silicon dioxide. The etch apparatus further includes: means for dissolving the silicon nitride coated on the filter into the etchant at a controlled dissolution rate sufficient to cause the selective etching; and means for coating the silicon nitride onto the filter to facilitate the selective etching.
