摘要:
Especially in order to carry out the so-called enzyme-coupled DNA hybridisation test in a closed cartridge including a microfluid system, using stored dry reagents, the reagents must be dissolved in the microfluid system and transported into the measuring chamber directly before the measurement. During the dissolution of the reagents in water, air cushions that cannot reach the measuring chamber must absolutely be prevented from forming upstream of the reagent liquid. According to an embodiment of the invention, the liquid measuring sample and the liquid reagents are transported in such a way that the air cushion is directed into the waste line and the measuring sample and the reagents are then introduced into the measuring chamber without any air bubbles. In this way, measuring errors can be avoided.

A simple method for diminishing the trench width in a photoresist structure to below the resolution limit is provided. A photoresist structure is produced and treated with an agent then contains a bulging constituent that reacts with functional groups of the photoresist structure. The bulging constituent causes a volume increase of the photoresist structure. The extent of the volume increase of the photoresist structures is controllable by varying various parameters.

The conveying trough of the vibrator conveyor is disposed spirally around a central pipe and is surrounded by a gasproof vessel. This vessel contains a treatment medium, preferably an electrolyte free of oxygen and water, into which the vibrator conveyor with thee central pipe dips partially. According to the invention, a gas cushion (10) is provided between the bottom (3) or the cover (4) of the central pipe (2) and the bottom (8) of the vessel (6). In this form of realization bulk material can be transported over great differences in height.

An apparatus is provided for surface treating agitable material that includes a conveyor trough for transporting the agitatable material. The trough is at least partially submerged in a treatment bath and it includes at least a first and second shaking chute each having a length along which the material is conveyed. The first and second chutes are disposed at angles from the horizontal such that the conveying direction of the first chute is substantially opposite to the conveying direction of the second chute.

摘要:
The invention relates to a method for the manufacture of positive resist structures by means of short-wave UV rays and has the objective to develop such a method in a manner such that increased sensitivity and resolution as well as high thermal stability and, in addition, transparency in the wave-length range above 260 nm can be achieved. According to the invention, it is provided for this purpose to use as the resist material copolymers of 1 to 70 mol % alkylmethacrylate with an alkyl radical having 1 to 4 C atoms, and 99 to 30 mol % of an ethylenically unsaturated monomer with chlorine and/or cyan substituents. The method according to the invention is particularly well suited for producing resist structures about 0.5 to 2 .mu.m thick by means of UV rays in the wave-length range between about 180 to 260 nm.
