Abstract:
The invention relates to a method for making microchannels on a substrate, and to a substrate including such microchannels, which can particularly be used in the production of microstructured substrates for microelectronic, microfluidic and/or micromechanical systems. The method includes a step of (a) making at least one or at least two patterns (2) on the surface of a lower layer (1), and a step (b) of depositing, onto the lower layer and the pattern(s), a layer (3) of a polymer material produced by polymerisation in an optionally remote plasma-enhanced chemical vapour deposition reactor (PECVD, optionally RPECVD) of an organic or organometallic monomer with siloxane functions, e.g. tetramethyldisiloxane. The layer of polymer material is deposited so as to create, in the place of the pattern and after the decomposition of said pattern, or between two patterns without development-decomposition, a channel (4a, 4b, 4c, 4d), which is closed on at least a portion of the length thereof.
Abstract:
Des sites de polymère sont formés sur un support (2). Ces sites sont soumis à un plasma de dépôt de matériau diélectrique (3) et réagissent préférentiellement avec ce plasma de manière à former des ouvertures (6) au niveau desdits sites. Un réseau de motifs est alors formé dans le matériau diélectrique (3) et/ou dans le polymère (4).
Abstract:
A novel porous film is disclosed comprising a network of silicon columns in a continuous void which may be fabricated using high density plasma deposition at low temperatures, i.e., less than about 250 ° C. This silicon film is a two-dimensional nano-sized array of rodlike columns. This void-column morphology can be controlled with deposition conditions and the porosity can be varied up to 90%. The simultaneous use of low temperature deposition and etching in the plasma approach utilized, allows for the unique opportunity of obtaining columnar structure, a continuous void, and polycrystalline column composition at the same time. Unique devices may be fabricated using this porous continuous film by plasma deposition of this film on a glass, metal foil, insulator or plastic substrates.
Abstract:
PURPOSE: A protein chip substrate and a method for fabricating the same by using plasma are provided to effectively fix protein on a substrate by depositing activating radical on a protein chip substrate using plasma. CONSTITUTION: A substrate(3) is placed on an inner electrode(4) accommodated in a plasma processing chamber(1). In this state, internal pressure of the plasma processing chamber(1) is lowered by using a vacuum device(7). Then, a precursor including activating radical is injected into the plasma processing chamber(1) together with carrier gas. Then, a temperature of the plasma processing chamber(1) is increased by using a heater(5) installed under the inner electrode(4). Voltage is applied to an external electrode(2) and the inner electrode(4) so that plasma is generated between the substrate(3) and the plasma processing chamber(1). A film including activating radical is uniformly deposited on the substrate(3) by plasma.
