    Abstract: The invention is a developer system for developing a PMMA photoresist having exposed patterns comprising features having both very small sizes, and very high aspect ratios. The developer system of the present invention comprises a developer tank, an intermediate rinse tank and a final rinse tank, each tank having a source of high frequency sonic agitation, temperature control, and continuous filtration. It has been found that by moving a patterned wafer, through a specific sequence of developer/rinse solutions, where an intermediate rinse solution completes development of those portions of the exposed resist left undeveloped after the development solution, by agitating the solutions with a source of high frequency sonic vibration, and by adjusting and closely controlling the temperatures and continuously filtering and recirculating these solutions, it is possible to maintain the kinetic dissolution of the exposed PMMA polymer as the rate limiting step.

  • Patent number: 6092937
    Abstract: The inventive dispenser mechanism uniformly develops a photosensitive layer on a substrate. The mechanism uses a developer head that moves in a substantially linear relative motion with respect to the substrate and dispenses a developer at a controlled rate. Contact of the developer material with the photosensitive layer commences a chemical reaction of developing. The mechanism also uses a rinse head that has the same motion as the developer head and travels at the same velocity. The rinse head dispenses a rinse material at a controlled rate. Contact of the rinse material with the developer material on the photosensitive layer retards the chemical reaction of developing. The rinse head waits for a predetermined dwell period after the developer head has dispensed the developer material before dispensing the rinse material. The mechanism may also use a suction head that has the same motion and velocity and removes loose material on a surface of the substrate.

    Abstract: A single resist layer lift-off process for forming patterned layers on a substrate, wherein a post-soak bake is used to control the extent to which chlorobenzene penetrates the resist layer. A post-metallization bake can also be employed to improve lift-off of the resist layer. The process of the present invention provides the resist profile with increased overhang length and the sidewalls of the resist profile with a negative slope. Such increased overhang length and negative slope prevent metallization of the sidewalls of the resist, and thus facilitate more rapid removal of the resist during lift-off.

  • Patent number: 4652106
    Abstract: When developing a coating such as for instance a light-sensitive exposed layer on a length or plate of material through ultrasonic agitation, the material is carried at a short distance or closely past a bar or a pipe extending substantially perpendicular to the advancing direction of the material and in the entire width of the coating. The bar or the pipe is caused to vibrate by a plurality of ultrasonic transducers while a developer is applied onto the coating adjacent the bar or the pipe in such a manner that the vibrations are transferred from the vibrating bar or pipe to the developer and to a stripe-shaped transverse area of the plate/the length including the coating. In this manner only the part of the developer having touched the ultrasonically agitated pipe or bar or already having hit the stripe of material currently developed is caused to vibrate by the ultrasonic transducers.

  • Patent number: 4612267
    Abstract: A process for the production of structures by the polymerization, or fragmentation of resist layers comprising the steps of effecting an incomplete exposure of the resist layer corresponding to the pattern of the structures, and of fully developing the structure in the resist layer by ultrasonic irradiation.An acoustic microscope is preferably used for the ultrasonic irradiation, whereby the formation of the structure in the resist layer may also be observed.

  • Patent number: 4447510
    Abstract: A process for producing relief copies wherein the light-hardenable layer of a light-hardenable copying material, which contains a photopolymerizable mixture, a photodimerizable polymeric compound or a diazonium salt polycondensation product, is exposed to a light image, the exposed layer is subjected to a brief ultrasonic treatment, and the unexposed areas of the layer are thereafter washed away by means of a developer. As a result of the ultrasonic treatment, shorter exposure times may be used and better in-depth hardening of the layer may be achieved.

  • Patent number: 4324849
    Abstract: A process is disclosed for recording an ultrasonic exposure pattern employing an ultrasonographic element containing a support and a recording layer unit. The recording layer unit is placed into contact with a transport liquid and imagewise ultrasonically exposed to accelerate imagewise diffusion from the recording layer unit to the transport liquid, thereby producing in the recording layer unit an ultrasonographic record. Diffusion is further accelerated imagewise by establishing a temperature differential within the transport liquid adjacent the recording layer unit.

  • Patent number: 4269914
    Abstract: An ultrasonographic element is disclosed comprised of first and second layers coated on a support, at least one of the layers being a silver halide emulsion layer. One of the layers contains a diffusible ion capable of altering the sensitivity of a silver halide emulsion while the other layer is capable of immobilizing the diffusible ion. Interposed between the layers is a barrier for impeding diffusion of the sensitivity altering ion in the absence of ultrasound. An ultrasonographic image is formed by contacting the element with a transport liquid, ultrasonically exposing the element imagewise to accelerate diffusion of the sensitivity altering ion between the layers, exposing the element to electromagnetic radiation and photographically processing the element to produce an image corresponding to the image pattern of ultrasonic exposure.

  • Patent number: 4257269
    Abstract: A method for producing a visible image of an object is disclosed in which a fermental plate is illuminated with ultrasonic waves and a latent image of the object is therefore produced therein which is developed using a solution of chromogenic substrates, comprising, for example, hydrogen peroxide and a water-soluble aromatic amine. An apparatus to practice the disclosed method comprises an ultrasonic generator to generate ultrasonic waves illuminating the object, a fermental plate to receive and convert the ultrasonic waves passed through the object to a visible image, and a tray filled with a developer to develop the latent image of the object in the fermental plate.

  • Patent number: 4232555
    Abstract: An ultrasonographic exposure apparatus is disclosed. An ultrasound transducer is positioned in a reservoir so that it is immersed in a transport liquid within the reservoir. An ultrasonographic element is positioned in contact with the transport liquid, and a damper is located to form an interface with the transport liquid adjacent the ultrasonographic element remote from the ultrasound transducer.

  • Patent number: 4228230
    Abstract: A process is disclosed of forming in a silver halide photographic element a visible image corresponding to a pattern of ultrasonic exposure. This process is characterized by providing in the photographic element internally fogged silver halide grains and contacting the element with a transport liquid in the presence of a solute capable of rendering the internally fogged silver halide grains developable in a surface developer. The element is then imagewise ultrasonically exposed and developed with a surface developer to produce a visible image defined by the pattern of ultrasonic exposure.
