    摘要: There is described an apparatus for treating objects with a treatment fluid, more especially an etching or developing machine for the production of printed-circuit boards, wherein the nozzle stock comprising a plurality of nozzles is designed so as to be plate-like. The edges of the plate-like nozzle stock are tightly connected to the housing walls so that the treatment chamber, to which the treatment fluid is applied, is bounded by the nozzle stock in one direction. The nozzles can be fitted and possibly also rotated through the nozzle stock from the side that is directed away from the treatment chamber, so that an effortless exchanging or aligning of the nozzles is possible from outside the treatment chamber (FIG. 1).

    摘要: A method for preferentially etching a piezoelectric material is disclosed wherein a portion of the piezoelectric material is controllably subjected to a concentrated thermal energy source with a force sufficient to alter the crystalline orientation of the piezoelectric material. The piezoelectric material is then treated with a suitable echant for a controlled duration, wherein the portion of the piezoelectric material altered by the concentrated thermal energy source is etched at a different etching rate than the unaltered piezoelectric material, to preferentially etch a controlled anaglyphic planar configuration upon the piezoelectric material.

    摘要: An apparatus for the in-situ cleaning of Low Pressure Chemical Vapor Deposition tube chambers (32) or Reduced Pressure Epitaxy bell jar chambers (42) having a base member (22) to create a vacuum seal upon engagement with the loading end of the chamber, at least one powered electrode (62) which protrudes from the base member into the chamber, at least on grounded electrode (60) which also protrudes from the base member into the chamber, a means for introducing gas (92) into the chamber, and an electrical network (16) that creates a radio frequency electrical field between the powered electrode and the grounded electrode. A plasma is created in the chamber by the interaction of the gas and the RF field, and the plasma etches unwanted deposits from the inner wall of the chamber. Several different configurations of electrode structures are shown.

    摘要: Selective etching of microelectronic devices comprising crystal substratess achieved by electrically masking conductive areas thereon which are not to be etched by ionic bombardment. The electrical masking is accomplished by biasing the selected areas with a bias voltage which will repel the ions, which are attracted to all of the unbiased portions of the microelectronic device.

    摘要: A photolithographic process useful for VLSI fabrication is disclosed for achieving side-wall profile control of poly lines, metal lines, contact and via openings. Layers of a first and second photoresist materials are formed on the poly, metal or oxide-covered substrate. The top layer is patterned by conventional processes to define the final device geometry. The bottom layer is exposed and over-developed to form an overhang structure about the line pattern or the contact/via opening. During the subsequent anisotropic plasma-assisted etching step, some ions or particles are passed obliquely over the overhang and bombard the opening corner, the side-wall and the under-cut area. The plasma-assisted etching step not only forms the poly or metal lines, or the contact or via opening, but also results in an opening with rounded corners and a smoothly tapered side-wall profile. The subsequent metal film deposition step results in a uniform film thickness around the edges of the opening. The process thus alleviates the problem of high contact resistance previously encountered as a result of dry etching the contact or via openings.
