IPC: H01L21/311
Filed: 1997-12-22
Abstract: A method for allowing the removal of a TEOS etch mask
layer utilizing an anisotropic technique such as reactive
ion etching. The use of the anisotropic technique results
in substantially less undercutting of the pad oxide layer
than wet chemical etching techniques. One embodiment of
the invention involves forming a polysilicon etch stop
layer under the pad TEOS layer.

Abstract: L'invention vise à perfectionner des mécanismes d'entraînement par inertie servant à des opérations de déplacement et de positionnement avec des actionneurs piézo-électriques ou électrostrictifs à extension linéaire, de manière que des objets lourds, serrés sans jeu avec un frottement par adhérence important atteignant approximativement la force de blocage des actionneurs, puissent être déplacés de manière très constante et sans hystérèse sur des longueurs de l'ordre du cm, à une vitesse de déplacement relativement élevée, et être positionnés sur des longueurs de l'ordre du nm. A cet effet, l'objet est solidarisé avec l'actionneur dans le sens d'extension ou de contraction dudit actionneur ou dans le dispositif de serrage où est monté un élément de transmission de force sous forme d'aiguille, fixé sur l'actionneur. L'inertie de la matière constituant l'objet n'agit pas à l'encontre du déplacement lorsque la longueur de l'actionneur varie par saccades sous l'effet d'une excitation électrique appropriée, de qui permet d'atteindre les avantages précités. La possibilité de déplacer des objets sur des longueurs de l'ordre du cm avec une grande précision de positionnement ouvre de nouvelles perspectives d'application pour les dispositifs de déplacement piézo-électriques ou électrostrictifs.

Abstract: A small amplitude signal output circuit comprises an output
section (11) for receiving a logic signal (IN1) to output a small
amplitude signal (OUT1) having a first and second transistors (M11,
M12) connected in series between a first source line (VDD) and a
second source line (VSS), and voltage control sections (13, 14)
connected between each of source lines (VDD, VSS) and the output
section (11) for reducing the output voltage supplied from the output
node, thereby allowing ON-resistance of the transistors (M11, M12)
of the output section (11) to be smaller. The small ON-resistance of
the transistors in turn allows variations in the output voltage of the
output circuit caused by variations in the fabrication process to be
smaller. The voltage control section (13) may have a function for
reducing variations in the output circuit due to temperature variation.

Abstract: A pulsed optical signal (13) of a network (23) is
monitored to obtain eye measurement data as a means of
obtaining an indication of signal degradation. Optical
sampling of the optical signal is effected by means of
an interferometer (2) in which sampling optical pulses
(8) are propagated equally through arms (3) and (4) of
the interferometer which include semiconducter optical
amplifiers (5,6). The optical signal to be monitored is
counter propagated through one arm of the interferometer,
thereby setting an interference condition of the
interferometer by cross modulation in one of the
semiconductor optical amplifiers. The output is detected
and converted to electrical signals which are processed
to obtain the eye measurement data. Parameters defining
the quality of the eye are extracted and processed to
locate defects occurring within a network by deploying
eye monitors (20,21,22) at a number of locations (A,B,C).
Elements (A,B,C) of the network may be controlled using
the output parameters.

Abstract: A method of cutting a decorative pattern in a barge board 1, or
alternatively a fascia board or a finial board, made from co-extruded
plastics material and having a front face 2, a rear face 3 and a cellular
core 4. The cellular core 4 can become stained when exposed by cutting
and the present method removes the stained cut edge from the line of sight
of the observer. The pattern is cut in the barge board 1 at an acute angle
of 45°-60° to the front face 2 and accordingly the portion of the cellular
core 4 exposed by cutting the pattern in the barge board 1 is not directly
visible from the ground. A small cut 5 is made at right angles to the front
face 2 before the angled cut is made to prevent damage to the cut edge
from handling. Also provided is a decorative barge board or fascia board

Abstract: The position of a boring head (16) during boring operation in the vicinity of
an existing utility conveyance (22) that radiates a locating signal can be determined
by establishing the ratio of the strength of the locating signal of the cable induced in
the boring head to the strength of the locating signal on the conveyance. Should the
ratio exceed a prescribed value, indicating that the boring head is too close to the
existing conveyance, then an alert is generated. Advantageously, the position of the
boring head during a boring operation may be controlled in feed-back loop fashion
in accordance with the ratio to maintain the boring head substantially parallel to the
existing conveyance.
