摘要:
A detached particle capture means by laser (4) allows them to be attracted and prevented from dropping back better than a traditional blow-off flushing means would. Various categories of attractive forces may be implemented. It will also be possible to use a particle destruction means, like a second high-power laser above the worked surface (3).

The invention concerns a process for forming an optical component comprising: a—formation of a multi-layer stack (32, 34) with an adjustment layer (30) made of a metal-semiconductor mix formed in or on the stack, b—etching a part of the multi-layer stack, including at least a part of the adjustment layer, c—an annealing step to contract the adjustment layer within less than 1 nm.
摘要:
An optical device reflecting a range of wavelengths comprised between 10 nm and 20 nm comprises alternate superposed first and second layers. The first layers are made of metal or metallic compound and the second layers are formed by an amorphous silicon compound chosen from a-Si—Hx, a-Si—CHx, a-Si—Cx, a-Si—OHx, a-Si—Fx, a-Si—FHx, a-Si—Nx, a-Si—NHx, x being comprised between 0.01 and 0.3. The use of second layers of amorphous silicon compound enables the mechanical stresses of the optical device to be stabilized up to at least 200° C. The optical device is preferably used as reflector for a lithography mask in the extreme ultraviolet (EUV).

The invention relates to a plasmon resonance optical detection device including a stack of layers comprising: a metal layer based on a noble metal that will generate said plasmon, a layer of dielectric material, at least one first semiconductor bond layer placed between said metal layer and said dielectric layer, said semiconductor layer covering a face of the metal layer.
摘要:
A process designed to prevent deposition of polarized contaminating particles on the surface of a micro-component consists, according to the invention, in sputtering a beam of particles between the contamination source and the micro-component. At least a part of the particles of the beam has an opposite polarity from that of the contaminating particles. The beam of particles is preferably a plasma and is designed to drag the contaminating particles away from the free surface of the micro-component to a collecting element. The invention also relates to a micro-component storage device and a thin layer deposition device respectively implementing such a process.
摘要:
The invention relates to a multilayer stack of fluoride materials usable in optics and its production process.This stack is constituted by alternating layers of a first, high index, fluoride material such as YF.sub.3 and a second, low index fluoride material such as LiF, able to form together a specific, stable compound such as YLiF.sub.4, so that the interface between two adjacent layers of the stack is at least partly formed from said compound.
摘要:
Material comprising a matrix made of semiconducting or insulating, transparent material in which core/shell type nanoparticles are dispersed, the core of which consists of a semiconductor and the shell of which is formed from a material chosen from the oxides TiO2 and/or CeO2. These nanocomposite materials may especially be used as optoelectronic absorbers.

摘要:
The nanoparticle production device includes a target provided with a nanoparticle source surface, and a magnetron generating a first magnetic field, the target being mounted on the magnetron and the first magnetic field forming field lines at the level of the nanoparticle source surface. The device further includes balancing means of the first magnetic field at the level of the target, arranged to close fleeing field lines of the first magnetic field and to keep said lines closed at the level of said nanoparticle source surface, said balancing means being distinct from the magnetron.
