摘要:
A method for forming a resist pattern comprises the steps of coating a resist on a substrate (12), baking the resist, selectively radiating electromagnetic waves or particle rays onto a surface of the resist, and developing the resist. The method further comprises, after the baking step and before the developing step, the step of cooling the resist in such a manner that a temperature control plate (8) is disposed parallel to and adjacent to the substrate (12).

In accordance with the present invention, a method is provided for converting a layer of polymeric material which lacks permeability to a more permeable form. The method can also be used to create or enhance patterned differential permeability within a given polymeric film or layer. It has been discovered that compounds/materials can be added to the polymeric material formulation and subsequently be leached from a film or layer cast from the formulation, to provide increased permeability of the layer as a whole, or to create or enhance permeability differentials within the polymeric layer. The additive used to alter permeability can be a photoactive compound or sensitizer such as the type of materials typically used in photoresists (for example, aryl azides, diazoquinones, and diazo homotetraminic acids), or can be a non-photosensitive or a nonphotoactive material. A photoactive material being a material which undergoes chemical change upon exposure to photons, electrons or ions. The additive used to alter permeability can be a compound/material which is leachable from the film in the same form in which it is added to the formulation, or it may be a compound/material which becomes leachable after treatment of the film with heat or radiation. The method of creating enhanced differential permeability in a resist film comprises: a) adding a compound/material to the polymeric resist formulation, wherein said compound/material or an altered derivative thereof can be subsequently leached from a film prepared using the polymeric resist formulation; b) applying the resist formulation to a substrate to provide a resist film; c) patternwise irradiating the resist film to create a latent image within the resist film, whereby the ability of the leachable material to be leached from the resist film is altered in the patternwise irradiated areas. This method of increasing permeability within a polymeric layer or enhancing the differential in permeability within a latent pattern in a polymeric layer is particularly useful in photolithographic processes used in the fabrication of electronic devices.

The patterned image includes on a substrate, a patterned image of a first resist material and patterned image of a second and different resist material on said first resist material. Said first material contains reactive hydrogen functional groups. The surface layer of the delineated and uncovered first resist material is reacted with a multifunctional organometallic material containing functional groups that are reactive with the functional groups of said first material. The method comprises: providing a first resist material on a substrate wherein said first material contains reactive hydrogen functional groups; providing a second and different resist material on top of said first resist material; selectively exposing said second resist material and developing said second and different resist material to form a resist mask; exposing said first resist material through the said resist mask and developing said first resist material; and reacting the surface layer of the exposed and uncovered first resist material with said organometallic material.

A process for the development of photoresist which uses no wet developing step is disclosed. An exposed photoresist layer is initially treated with an organosilicon compound such that silicon atoms bound to the exposed photoresist resulting in different etch resistance in the exposed and unexposed areas. Following such treatment, the photoresist layer is selectively etched to define a mask image in the photoresist layer. Conventional processing steps can be used in conjunction with this novel process to fabricate metallic conductor structures using additive or subtractive processes.

Ultraviolet radiation process applies to manufacture semiconductor devices in order to enhance the thermal stability of the photoresist film of semiconductors wafers. A method, in ultraviolet radiation process, enabling effective treatment of the photoresist employing ultraviolet irradiation by preventing the deformation of the photoresist which is caused by exposing it to high ultraviolet radiation at the beginning of exposure. This method employs ultraviolet irradiation, in which the photoresist is exposed to ultraviolet radiation of low intensity at the beginning of exposure, and then exposed to ultraviolet radiation,the intensity of which increases little by little or in steps.

Die Erfindung betrifft eine Transport- und Abquetsch einrichtung (1) für Druckmaterialien, wie Druckplatten, licht empfindlich beschichtete Papiere. Folien od.dgl. in einem Verarbeitungsgerät. Die Einrichtung umfaßt eine Andruck walze (20) und eine angetriebene Transportwalze (21), an welche die Andruckwalze (20) mit Hilfe von Andruckeinrich tungen (22, 22′) beigestellt wird, um einen sicheren Trans port einer Druckplatte und das Abquetschen von Entwickler flüssigkeit od.dgl. Chemikalien von der Druckplattenober fläche in dem Verarbeitungsgerät zu gewährleisten. Sowohl die Andruck- als auch die Transportwalze ist jeweils von einer Steckachse durchsetzt, die aus einem Innenrohr und in dieses beiderseits eingesetzten Lagerzapfen besteht. Die Steckachsen sind derart gelagert, daß ihre Durchbiegung bei Belastung ohne Einfluß auf die Durchbiegung der Walz rohre der Walzen (20, 21) bleibt, wodurch die Gesamtdurch biegung des Walzenrohrs (5) gering ist. Die Transportwalze (21) durchsetzt Seitenschilde (24, 24′) mit ihren Lagerzap fen, die in innerhalb von Lagerschalen (26, 26′) angeord neten Lagern gelagert sind. Von den Lagerzapfen der An druckwalze (20) abgesetzte Zapfenenden (27, 27′) sind in Führungsleisten (25, 25′) gelagert, die auf der Innenseite von Seitenschilden von Befestigungsschrauben (30, 30′) durchsetzt sind.
