The invention relates to a layered structure comprising The invention further relates to the use of a substrate coated with such a layered structure for high shear and/or high impact applications and to a method to cover a substrate with such a layered structure.

Layered structure

An intravascular stent () has a surface coated with a biocompatible layer. The layer contains a diamond like nanocomposite material. This nanocomposite material comprises carbon, hydrogen, silicon and oxygen as constituent elements. The layer has a stress which is less than 150 MPa in order to ensure a high degree of flexibility and a complete expandability. This lower stress is obtained by the inclusion of relatively large amounts of Si:O bonds. In a preferable embodiment the layer with diamond like nanocomposite material covers the stent () for 100%. This is obtained by allowing the stent to move freely along a wire during CAVD deposition.

The invention relatse to a copper diffusion barrier which includes a diamond-like material includes carbon, hydrogen, silicon, oxygen and a metal and is a copper diffusion barrier. Another aspect of the invention relates to an integrated circuit which includes a copper interconnect, a dielectric material and the copper diffusion barrier.

The invention relates to a material including carbon, oxygen, silicon and hydrogen and having a dielectric constant of from about 2.1 to about 3.0 where an FTIR scan of the material includes at least two major peaks signifying Si&#x2014;CHbonding. The invention further relates to a material which has a variable dielectric constant through the thickness of the material. Another aspect of the invention is the method of making the material.

Materials having low dielectric constants and method of making

A diamond-like carbon-containing material useful as a coating for electronic devices including field emission devices and color television tubes, the coatings having both low secondary electron emission coefficients of less than unity and electrical resistivity tunable over a range of from about 10e to about 10e .

Electrically tunable low secondary electron emission diamond-like coatings and process for depositing coatings

The invention relates to fluorine-doped coatings which include a diamond-like composition containing carbon, silicon, oxygen, hydrogen, and fluorine on various substrates. Preferred substrates include flexible substrates, precision-edged substrates, and electrosurgical instruments. The present invention also relates to a method of making a substrate coated with a fluorine-doped diamond-like coating which includes positioning the substrate in a vacuum coating chamber and depositing a diamond-like composition containing carbon, silicon, oxygen, hydrogen, and fluorine onto the substrate by co-deposition of clusterless particle beams comprised of ions, atoms, or radicals of the carbon, silicon, oxygen, hydrogen, and fluorine, the mean free path of each particle species being in excess of the distance between its source and the growing particle coating surface of the substrate.

Fluorine-doped diamond-like coatings

The present invention relates to a unique hard coating that provides the necessary characteristics for flat panel display plastic substrates because the coating is amorphous and is comprised of C, H, Si and O. The coating of the present invention is hard, optically transparent, scratch and abrasion resistant and hydrophobic. It is deposited by a low density, low temperature plasma enhanced chemical vapor deposition (PECVD) process and exhibits excellent barrier protection and reduced permeability to moisture, oxygen, helium and other vapors.
