Abstract: The present invention relates to a thermostatted pilot, with piezoelectric resonator (11), which is insensitive to climatic variations. The piezoelectric resonator is inserted into a thermostatted enclosure (6) comprising a body (10) and a cover (9). To improve the frequency stability of the pilot, when the temperature, pressure and level of humidity vary, the thermostatted enclosure (6) is made leaktight. The cover (9) and the body (10) of the enclosure are sufficiently rigid so as not to deform under the action of pressure variations outside the enclosure (6). Sealing compound, an adhesive or brazed seal ensure the leaktightness between the cover (9) and the body (10) of the thermostatted enclosure. Applications to quartz pilots which are stable in frequency over a wide temperature range. <IMAGE>

Abstract: With a single wafer dry etching equipment, the trench formation process in a silicon wafer is usually monitored by time-based ellipsometry techniques and destructive SEM cross-section analysis to ex-situ determine trench profile and depth. In particular, the thickness of the SiO₂ layer which is redeposited during the trench formation is monitored by ellipsometry. On the contrary, the apparatus (20) of the present invention allows full in-situ and on-line monitoring of the trench formation process. It is essential that the chamber (22) of the etching equipment be provided with side and top quartz windows. Two spectrometers (30A, 30B) are connected to their respective windows (26A, 26B) by two optical fibers (29A, 29B), so that the optic fibers look at the wafer through the plasma (27) at zero and normal angle of incidence with respect to the wafer plane, respectively. Both spectrometers are tuned to look at the same species radiation, e.g. one SiBr band. Signals outputted by the spectrometers viewing the side and top windows are different:
     side signal Il as a function of time t is representative the band intensity variation during the trench etching;   top signal It as a function of time t is representative of both the band intensity variation and the wafer surface reflectivity. Thus, signal It is a mixed signal with band intensity and interferometric components.   
     According to the monitoring method of the present invention the interferometric component signal Ii is extracted by subtracting the side from the top signal. The interferometric signal Ii is of the quasi-periodic damped sine-shaped type. Then, envelope signals Ja and Jb of said interferometric signal Ii, and finally the amplitude variation signal I of the said envelope signals are generated. 
     The trench depth D is determined in real time by equation: 
 
D = k√           I(t=0)     ¯                       -     ¯                       I     ¯             
 
wherein k is a coefficient depending on the etching system that is used and is determined by a preliminary calibration step. 
     The thickness of the redeposited SiO₂ layer is computed in real time by the equation:       
 wherein λ is the wavelength of the selected species (e.g. SiBr), n is the refractive index of the redeposited SiO₂ layer, and tu is the half-period of the interferometric signal Ii. 
     D and Th are continuously monitored until the desired final parameters Df and Thf are obtained. 
     The above method has important applications in the fabrication of deep trenches for DRAM storage capacitors.

Abstract: The invention concerns a vehicle-parking system (1) with a number of vehicle pallets (4) which can be displaced on a planar network of tracks running at right angles to each other. Each pallet has its own drive unit which drives rollers which move the pallet (4). In order to enable the direction of travel of the pallet to be selected exclusively by means of fixed control means, the invention proposes that the drive unit simultaneously drives the rollers for both the mutually perpendicular directions of travel (6, 7). Located along the tracks are fixed rails (8, 9) which can be selectively brought into contact with the rollers for either one or the other of the two mutually perpendicular directions of travel (6, 7).

Abstract: Dans cette invention, un réseau neuronal à apprentissage en direct pour un procédé et un système de commande de processus apprend en retrouvant des ensembles d'apprentissage provenant du train de données de traitement. Le réseau neuronal détecte la disponibilité de nouvelles données d'apprentissage et construit un ensemble d'apprentissage en retrouvant les données d'entrée correspondantes. Le réseau neuronal configuré en utilisant l'ensemble d'apprentissage. Après un certain temps, plusieurs ensembles d'apprentissage sont présentés au réseau neuronal. Lorsque plusieurs présentations sont nécessaires pour configurer efficacement le réseau neuronal, une mémoire intermédiaire d'ensembles d'apprentissage se remplit et est mise à jour au fur et à mesure que de nouvelles données d'apprentissage se trouvent disponibles. La taille de la mémoire intermédiaire est choisie en fonction des besoins d'apprentissage du réseau neuronal. Lorsque la mémoire intermédiaire est pleine, un nouvel ensemble d'apprentissage supprime l'ensemble d'apprentissage le plus ancien se trouvant en haut de la pile de la mémoire intermédiaire. Les ensembles d'apprentissage situés dans la pile de la mémoire intermédiaire peuvent être présentés une ou plusieurs fois à chaque fois qu'un nouvel ensemble d'apprentissage est construit. Une base de données historique de données horodatées peut être utilisée pour construire des ensembles d'apprentissage lorsque des donées d'entrée d'apprentissage ont un délai d'attente entre le temps d'essai et la disponibilité pour le réseau neuronal. Les horodateurs pour les donnés d'entrée d'apprentissage sont utilisés pour sélectionner l'horodateur approprié au niveau duquel les donnés d'entrées sont récupérées pour être utilisées dans l'ensemble d'apprentissage. En utilisant la base de donnés historique, le réseau neuronal peut être configuré rétrospectivement en recherchant la base de données historique et en construisant des ensembles d'apprentissage basés sur des données anciennes.
