The tools easily transition between open and closed modes on demand. According to one general strategy, environmentally controlled pathway(s) couple the ambient to one or more process chambers. Air amplification capabilities upstream from the process chamber(s) allow substantial flows of air to be introduced into the process chamber(s) on demand. Alternatively, the fluid pathways are easily closed, such as by simple valve actuation, to block egress to the ambient through these pathways. Alternative flows of nonambient fluids can then be introduced into the process chamber(s) via pathways that are at least partially in common with the pathways used for ambient air introduction. In other strategies, gap(s) between moveable components are sealed at least with flowing gas curtains rather than by relying only upon direct physical contact for sealing. Full Article

pie PIEZOELECTRIC DEVICE AND METHOD FOR MANUFACTURING PIEZOELECTRIC DEVICE By www.freepatentsonline.com Published On :: Thu, 22 Jun 2017 08:00:00 EDT In a method of manufacturing a piezoelectric device in which a piezoelectric thin film on which functional conductors are formed is fixed to a support substrate by a fixing layer, an alignment mark is formed on one main surface of a light-transmitting piezoelectric substrate. A sacrificial layer is formed on a main surface of the piezoelectric substrate with reference to the alignment mark and the fixing layer is formed so as to cover the sacrificial layer and is bonded to the support substrate. The piezoelectric thin film is formed by being separated from the piezoelectric substrate and the functional conductors are formed on the surface of the piezoelectric thin film with reference to the alignment mark. The piezoelectric device is able to be manufactured while positions of formation regions of conductors are adjusted efficiently. Full Article
pie SYSTEM AND FABRICATION METHOD OF PIEZOELECTRIC STACK THAT REDUCES DRIVING VOLTAGE AND CLAMPING EFFECT By www.freepatentsonline.com Published On :: Thu, 29 Jun 2017 08:00:00 EDT A system and method provides a piezoelectric stack arrangement for reduced driving voltage while maintaining a driving level for active piezoelectric materials. A stack arrangement of d36 shear mode single crystals of both air X-cut and Y-cut ±1:45° (±20°) arrangement are bonded with discrete conductive pillars to form a shear crystal stack. The bonding area between the neighboring crystal parts is minimized. The bonding pillars are positioned at less than a total surface are of the single crystal forming the stack. The stack fabrication is facilitated with a precision assembly system, where crystal parts are placed to desired locations on an assembly fixture for alignment following the preset operation steps. With the reduced clamping effect from bonding due to lower surface coverage of the discrete conductive pillars, such a piezoelectric d36 shear crystal stack exhibits a reduced driving voltage while maintaining a driving level and substantial and surprisingly improved performance.

pie MEMS PIEZOELECTRIC DEVICE AND CORRESPONDING MANUFACTURING PROCESS By www.freepatentsonline.com Published On :: Thu, 29 Jun 2017 08:00:00 EDT A MEMS piezoelectric device includes a monolithic semiconductor body having first and second main surfaces extending parallel to a horizontal plane formed by first and second horizontal axes. A housing cavity is arranged within the monolithic semiconductor body. A membrane is suspended above the housing cavity at the first main surface. A piezoelectric material layer is arranged above a first surface of the membrane with a proof mass coupled to a second surface, opposite to the first surface, along the vertical axis. An electrode arrangement is provided in contact with the piezoelectric material layer. The proof mass causes deformation of the piezoelectric material layer in response to environmental mechanical vibrations. The proof mass is coupled to the membrane by a connection element arranged, in a central position, between the membrane and the proof mass in the direction of the vertical axis. Full Article
