Abstract:
The invention relates to a field effect transistor assembly and an integrated circuit array. The field effect transistor assembly contains a substrate, a first wiring plane with a first source/drain region on the substrate and a second wiring plane with a second source/drain region above the first wiring plane. The field effect transistor assembly also comprises at least one vertical nanoelement as a channel region, which is situated between and coupled to both wiring planes. The nanoelement is at least partially surrounded by electrically conductive material, forming a gate region, whereby electrically insulating material is provided between the nanoelement and the electrically conductive material to act as a gate insulating layer.

The invention relates to a nanotube array, comprising a substrate, a catalyst layer having one or more partial areas on the surface of the substrate and at least one nanotube parallel to the surface of the substrate on the surface of the catalyst layer. The nanotube array also has an electrically insulating layer between the substrate and the nanotubes and a topography such that the end segments of the at least one nanotube rest on the electrically insulating layer while its central segment rests freely. The invention also relates to a method for the production of said nanotube array.
Abstract:
A biosensor has a substrate with a surface incorporating one or more electrodes under a carbon cover incorporating a trap module. The sensor forms part of a diagnostic electronic circuit determining the electrode capacity. The carbon layer is primarily diamond that insulates and renders the electrode passive. The carbon layer structure forms no electrical link between the electrodes. The electrodes are fabricated of electrically-conducting carbon. Also claimed is a manufacturing process for the sensor in a hydrogen atmosphere pressurised to between 1 and 4 hectopascals and at a temperature of between 600 and 1000[deg]C, and in the presence of a hydrocarbon gas, oxygen plasma and/or acid.

Nanotube array comprises a substrate; a catalyst layer having partial regions on the surface of the substrate; nanotubes (205) arranged on the surface of the catalyst layer parallel to the surface of the substrate; and pores arranged parallel to the surface of the substrate. An Independent claim is also included for a process for the production of the nanotube array. Preferred Features: The array has an electrically insulating layer (202) between the substrate and the catalyst layer. The partial regions of the catalyst layer are decoupled from each other. The array also has a switching circuit arrangement by which the nanotubes can be controlled and/or read.
Abstract:
Process for growing nanotubes comprises contacting a substrate (100) having a region (107) covered with a photolacquer (101) and a free region (106) with a compound of a catalytically active metal to form a layer on the substrate; contacting the treated substrate with a basic solution so that the catalytically active metal compound is converted into the corresponding hydroxide of the metal; removing the photolacquer so that the hydroxide remains on the free region of the substrate; reducing the hydroxide to the corresponding metal; and growing nanotubes on the metal. Preferred Features: Iron is used as the catalytically active metal. The catalytically active metal compound is FeCl3 or a solution iron salt. The basic solution is a solution of NH3 having a concentration of 5%. The photolacquer is removed with acetone under the action of ultrasound and rinsing with isopropanol.
