20100300207 | PRESSURE SENSOR FOR HARSH MEDIA SENSING AND FLEXIBLE PACKAGING - MEMS pressure sensing elements, the fabrication methods of the sensing elements, and the packaging methods using the new sensing elements are introduced to provide a way for a harsh media absolute pressure sensing and eliminating the negative effects caused by the gel used in the prior art. The invention uses vertical conductive vias to electrically connect the enclosed circuit to the outside, and uses a fusion bond method to attach a cap with the embedded conductive vias over a device die having a circuit for example a piezoresistive Wheatstone bridge to sense pressure. New packaging methods comprise a) a two-pocket housing structure and using a surface mounting method to attach a new sensing element into one pocket by a ball grid array (BGA), and b) a single pocket structure and using conventional die attach and wire bonding. Both methods can be used for harsh media pressure sensing but without the negative effects caused by the gel in prior art. | 12-02-2010 |
20110023618 | LOW PRESSURE SENSOR DEVICE WITH HIGH ACCURACY AND HIGH SENSITIVITY - Pressure non-linearity in a low pressure sensor device formed from a silicon diaphragm with an embedded piezoresistive transducer is reduced by using a shallow boss or thin stiffener on an ultra-thin diaphragm while the pressure sensitivity of the device is increased with corner trenches. | 02-03-2011 |
20110132085 | Pressure Sensor Device with Breakwater to Reduce Protective Gel Vibration - A piezoresistive pressure sensor that uses a protective gel to protect the piezoresistive device is susceptible to lead wire failure by vibration-induced waves in the protective gel. Such waves can be reduced and the device made more robust by the use of three-dimensional structures in the gel, which are configured to reduce and/or re-direct vibration-induced pressure waves in the gel. The structures are referred to as “breakwaters” in that they protect lead wires and lead wire connections from wave fronts and the damage that wave-induced pressure on the lead wires causes. | 06-09-2011 |
20110232389 | Grooved Structure For Die-Mount And Media Sealing - Dual piezoresistive transducers formed into a single silicon die, are anodically bonded to a pedestal. Two separate pressure ports extend through a plastic housing. The port openings inside the housing are surrounded by a groove having a shape and size that accepts the pedestal. A thin, liquid adhesive is deposited into the groove and allowed to level out. The pedestal is placed into the adhesive and embeds itself therein. Adhesive overflow into the ports is avoided by dimensioning the groove and depositing an amount of adhesive that will fill the groove but not overflow when the pedestal is placed therein. Once the adhesive cures, the adhesive bond strength is greater due to the adhesive being in shear relative to the groove side walls and pedestal sidewalls. The grooved structure provides an apparatus and methodology for precise die mounting and media sealing. | 09-29-2011 |
20110278682 | Optimized Bonding Wire - Any two segments of a wire bonded on two bond pads at different elevations can be distinguished by a stationary node (or zero-displacement) during its second-mode vibration. In order to boost the natural frequency of such a bond wire to avoid a second-mode resonance occurring at the lowest frequency in the in-plane vibration, a wire can be optimized by connecting two equalized (shortest possible) wire segments to replace a wire consisting of a larger segment and a shorter segment. The purpose is to re-distribute a larger vibration movement in the longer segment with a lower stiffness of an arbitrary bond wire to two smaller equalized segments of an optimized wire to reduce an in-plane vibration to significantly improve the wire natural frequency and reliability in a harsh vibration environment such as over 30 kHz. | 11-17-2011 |
20120216622 | ROBUST DESIGN OF HIGH PRESSURE SENSOR DEVICE - In a pressure sensing element made of piezoresistors formed into a silicon substrate, thermally-induced stresses on the piezoresistors and thermally-induced voltage offsets can be reduced by thinning the substrate prior to forming the resistors and then forming the resistors into the thinned-out recess. Forming a circular or disk-shaped recess in the substrate and then forming the resistors therein is believed to cause thermally-induced stresses to be evenly distributed and/or cancelled out on all four piezoresistors of a Wheatstone bridge circuit. | 08-30-2012 |
20130087863 | DIFFERENTIAL PRESSURE SENSOR DEVICE - A MEMS differential pressure sensing element is provided by two separate silicon dies attached to opposite sides of a silicon or glass spacer. The spacer is hollow. If the spacer is silicon, the dies are preferably attached to the hollow spacer using silicon-to-silicon bonding provided in part by silicon oxide layers.

The pressure sensing element also includes a plurality of piezoresistors, which are operable to generate a signal based on the amount of deflection in the diaphragm. At least one trench is integrally formed as part of the pressure sensing element, and an adhesive connects the pressure sensing element to the at least one substrate such that at least a portion of the adhesive is attached to the trench and redistributes thermally induced stresses on the pressure sensing element such that the thermally induced noise is substantially eliminated. | 08-01-2013 |
20140000376 | PRESSURE SENSING DEVICE WITH STEPPED CAVITY TO MINIMIZE THERMAL NOISE | 01-02-2014 |
20140137653 | PIEZORESISTIVE TRANSDUCER WITH LOW THERMAL NOISE - In a MEMS PRT having a diaphragm that is located offset from the center of the die, thermally-induced thermal noise in the output of a Wheatstone bridge circuit is reduced by locating the Wheatstone bridge circuit away from the largest area of the die and supporting pedestal. | 05-22-2014 |
20150330856 | PRESSURE SENSOR DEVICE WITH HIGH SENSITIVITY AND HIGH ACCURACY - The voltages output from a low-pressure MEMS sensor are increased by increasing the sensitivity of the sensor. Sensitivity is increased by thinning the diaphragm of the low pressure sensor device with corner trench. Nonlinearity increased by thinning the diaphragm is reduced by simultaneously creating a cross stiffener to the bottom side of the diaphragm. A rim, anchors, and a stiffener pad can also be added to further stiffen the thinner diaphragm and further reduce pressure nonlinearity. | 11-19-2015 |

20140256047 | DOSE AND LOCATION CONTROLLED DRUG/GENE/PARTICLE DELIVERY TO INDIVIDUAL CELLS BY NANOELECTROPORATION - A simple and low cost method of producing sealed arrays of laterally ordered nanochannels interconnected to microchannels of tunable size, over large surface areas, is disclosed. The method incorporates DNA combing and subsequent imprinting. Associated micro and macroscale inlets and outlets can be formed in the same process or manufactured later in low cost, non-cleanroom techniques. The techniques embrace two procedures, generating DNA nanostrands and translating these strands into nanoscale constructs via imprinting. Devices incorporating the novel arrays have a first microchannel, a second microchannel and a nanochannel that is substantially linear and which defines an axis. The nanochannel is connected at its open ends to the microchannels, which are aligned along the axis. Methods for precise dose delivery of agents into cells employing the devices in nanoelectroporation methods are also disclosed. | 09-11-2014 |
20150252149 | PREPARATION OF HIGH MOLECULAR WEIGHT, FUNCTIONALIZED POLY(METH) ACRYLAMIDE POLYMERS BY TRANSAMIDATION - The present invention provides processes for making higher molecular weight, functionalized poly(meth)acrylamide polymer products. As an overview, the processes use (trans)amidation techniques in the melt phase to react one or more high molecular weight amide functional polymers or copolymers with at least one co-reactive species comprising at least one labile amine moiety and at least one additional functionality other than amine functionality. In practical effect, the processes of the present invention thus incorporate one or more additional functionalities onto an already formed or partially formed polymer rather than trying to incorporate all functionality via copolymerization techniques as the polymer is formed from constituent monomers. The methods provide an easy way to provide functionalized, high molecular weight poly(meth)acrylamide polymer products. | 09-10-2015 |
