  • Patent number: 10753959
    Abstract: A probe card includes a conductive body, an insulation block, and a plurality of conductive microsprings. The insulation block covers at least one side of the body and at least partially encloses the microsprings. A first end of each microspring is connected to the conductive body and a second end is exposed from the insulation block. In operation, the probe card is moved onto one or more semiconductor devices to be tested. As the probe card is moved toward the semiconductor devices, the second ends of the conductive microsprings come into contact with contact pads on the semiconductor devices. The insulation block encloses the microsprings, which prevents the microsprings from buckling or making contact with each other. As a result, the probe card produces fewer false positives and false negatives during the testing process.

  • Patent number: 10490472
    Abstract: Conventional packages for 5G applications suffer from disadvantages including high mold stress on the die, reduced performance, and increased keep-out zone. To address these and other issues of the conventional packages, it is proposed to pre-apply a wafer-applied material, which remains in place, to form an air cavity between the die and the substrate. The air cavity can enhance the die's performance. Also, since the wafer-applied material can remain in place, the keep-out zone can be reduced. As a result, higher density modules can be fabricated.

  • Patent number: 10151656
    Abstract: A pressure sensor includes a pressure sensor element, a joint provided to a target member, and an attachment member that is fitted into the joint through the connection section and connected to the target member. Each of the pressure sensor element and the joint is formed of a material that is not embrittled upon being in contact with a fluid to be measured that embrittles a material, and more rigid than the attachment member. The connection section is subjected to a plastic deformation connection (metal flow). An expensive hydrogen embrittlement resistant material is used for the pressure sensor element and the joint that are brought into contact with the fluid to be measured, and an inexpensive material is used for the attachment member that is not brought into contact with the fluid to be measured, thereby reducing the production cost of the pressure sensor.

  • Patent number: 10153382
    Abstract: A mechanical memory transistor includes a substrate having formed thereon a source region and a drain region. An oxide is formed upon a portion of the source region and upon a portion of the drain region. A pull up electrode is positioned above the substrate such that a gap is formed between the pull up electrode and the substrate. A movable gate has a first position and a second position. The movable gate is located in the gap between the pull up electrode and the substrate. The movable gate is in contact with the pull up electrode when the movable gate is in a first position and is in contact with the oxide to form a gate region when the movable gate is in the second position. The movable gate, in conjunction with the source region and the drain region and when the movable gate is in the second position, form a transistor that can be utilized as a non-volatile memory element.

  • Patent number: 10131536
    Abstract: The present disclosure relates to a MEMs package having a heating element configured to adjust a pressure within a hermetically sealed chamber by inducing out-gassing of into the chamber, and an associated method. In some embodiments, the MEMs package has a CMOS substrate having one or more semiconductor devices arranged within a semiconductor body. A MEMs structure is connected to the CMOS substrate and has a micro-electromechanical (MEMs) device. The CMOS substrate and the MEMs structure form a hermetically sealed chamber abutting the MEMs device. A heating element is electrically coupled to the one or more semiconductor devices and is separated from the hermetically sealed chamber by an out-gassing layer arranged along an interior surface of the hermetically sealed chamber. By operating the heating element to cause the out-gassing layer to release a gas, the pressure of the hermetically sealed chamber can be adjusted after it is formed.

  • Patent number: 10071902
    Abstract: A sensor is achieved by applying a layer of a mixture that contains polymer and conductive particles over a substrate or first surface, when the mixture has a first viscosity that allows the conductive particles to rearrange within the material. An electric field is applied over the layer, so that a number of the conductive particles are assembled into one or more chain-like conductive pathways with the field and thereafter the viscosity of the layer is changed to a second, higher viscosity, in order to mechanically stabilize the material. The conductivity of the pathway is highly sensitive to the deformations and it can therefore act as deformation sensor. The pathways can be transparent and is thus suited for conductive and resistive touch screens. Other sensors such as strain gauge and vapor sensor can also be achieved.
