Abstract: METHODS FOR FORMING THICK SELF-SUPPORTING MASKS A method of constructing a relatively thick, self-supporting mask suitable for electron beam projection processes.  Thickness is achieved by multiple steps of coating with resist, exposure and development.  Either positive or negative resist may be used for second and subsequent coatings.  Second and subsequent exposures are directed through the first relatively thin mask formed and through the substrate to eliminate critical alignment of subsequent masks.  When desired thickness is achieved an even thicker frame may be fabricated for support purposes and the mask may then be lifted off the substrate on which it had rested during the fabrication steps. When positive resist is employed, the resist remaining after development is baked on to give added structural strength to the mask.  This baked resist can be coated with an additional layer of metal by evaporation or sputtering to give greater mechanical strength.  When negative resist is employed, the portions of the resist protected by the relatively thin previously formed mask are removed and additional material is plated to increase the thickness and strength of the mask.  The unprotected resist material is then also removed.  The completed mask can be further strengthened by evaporating or sputtering an additional layer of metal or oxide.

Abstract: Abstract Of The Disclosure An optical fiber tap for tapping optical energy from an optical fiber includes an optical waveguide positioned adjacent to the fiber for collecting light signals therefrom.          The optical waveguide preferably has an index of refraction greater than the index of refraction of the fiber.  A coupling material interconnects the fiber and the optical waveguide for conducting light from the fiber into the waveguide, the coupling material preferably having an index of refraction between the indexes of the waveguide and the fiber.  A photo-detector is coupled to one end of the waveguide for receiving light signals therefrom and converting the light signals to corresponding electrical signals.  When the tap is used to remove light from the cladding of an optical fiber, pressure is applied to preselected points on the fiber upstream of the tap to couple optical signals from the fiber core into the fiber cladding.  When the tap is used to remove light from the core of an optical fiber from which the cladding has been removed, optical signals are collected directly from the fiber core and no pressure assembly is required.
