The invention relates to a method for the manufacture of packaged components. The invention is based here on the problem of facilitating the application of covers with lateral dimensions that are smaller than the lateral dimensions of the functional substrate. For this purpose, a plate-like cover substrate is mounted on a carrier substrate. Then, on the uncovered side of the plate-like cover substrate, trenches are inserted, so that a composite part is obtained with the carrier substrate and individual covering parts that are separated from each other by the trenches, but interconnected by the carrier substrate. The covering parts of the composite part are connected with a functional substrate with a plurality of components. Then, the connection of the covering parts is dissolved with the carrier substrate, and the carrier substrate is removed, so that a composite is obtained with the functional substrate and a plurality of covering parts that cover functional areas.

The present invention relates to the use of lead-free and phosphate-containing glasses, preferably colored and filter glasses which absorb light in the infrared region (IR-region), in a precision molding process. Preferably, the content of fluorine in the glass is low. Advantageously, so optical constituents can be produced without finishing, such as for example lenses for digital cameras. By the use according to the present invention, also other optical constituents can be produced which can be directly used for a corresponding technical purpose. For an advantageous use, the optical constituents produced by precision molding can be used in the fields imaging, projection, telecommunications, optical communications engineering and laser technology.

The glass container stores and preserves pharmaceutical or diagnostic solutions for medicinal purposes. So that the container is free of silicones and other residues, it is provided with an amorphous, transparent anti-adherent coating ( ) over its entire interior surface from its bottom over the wall ( ) to the closure device ( ). This anti-adherent coating ( ) is free of heavy metals, free of silicones, is stable after autoclaving at about 120&deg; C. for about 20 min or hot air sterilization for 30 min at 300&deg; C., has a contact angle for wetting with water of &gE;80&deg;, contains silicon, oxygen, carbon, fluorine and hydrogen and is deposited by a PECVD method, especially a PICVD method. If the coating contains less than 0.1% by weight fluorine, then it contains greater than or equal to 10% by weight carbon, but if it contains greater than or equal to 0.1% fluorine then it contains greater than or equal to 5% by weight carbon.

The invention is directed to a method for producing low sintering fine-particle multicomponent glass powder having a particle size of the primary particle in the nanometer range. The method utilizes microemulsion techniques with subsequent separation of the particles out of the emulsion and calcination for utilization as glass flow having a sintering temperature &lt;900.degree. C. or in a glass flow, for generating thin transparent layers or for generating color decorations on glass, glass ceramic or ceramic substrates after adding a coloring pigment to the glass flow. The microemulsion for producing the nanoscale glass powder particles is generated from a nonionic ambiphilic emulsifier with a component of 10 to 15 percent by weight on the emulsion, from an oil phase having a portion of 50 to 70 percent by weight and a glass precursor-containing aqueous salt solution having a portion of up to 31.3 percent by weight with salt contents of up to 45 percent by weight.
