  • Patent number: 10734113
    Abstract: A computer aided medical method includes the following steps. An initial symptom of a patient and context information is collected through an interaction interface. Actions in a series are sequentially generated according to the candidate prediction models and the initial symptom. Each of the actions corresponds to one of the inquiry actions or one of the disease prediction actions. If the latest one of the sequential actions corresponds to one of the disease prediction actions, potential disease predictions are generated in a first ranking evaluated by the candidate prediction models. The first ranking is adjusted into a second ranking according to the context information. A result prediction corresponding to the potential disease predictions is generated in the second ranking.

  • Publication number: 20200212019
    Abstract: An electronic package is provided, including: a first substrate having a first insulating portion; a first electronic component disposed on the first substrate; a second substrate having a second insulating portion and stacked on the first substrate through a plurality of conductive elements; and a first encapsulant formed between the first substrate and the second substrate. The first insulating portion of the first substrate differs in rigidity from the second insulating portion of the second substrate. As such, during a high temperature process, one of the first substrate and the second substrate pulls at the other to bend toward the same direction, thereby reducing warpage deviation of the overall electronic package. The present invention further provides a method for fabricating the electronic package.

  • Publication number: 20200091059
    Abstract: Provided is a substrate structure including a substrate body, electrical contact pads and an insulating protection layer disposed on the substrate body, wherein the insulating protection layer has openings exposing the electrical contact pads, and at least one of the electrical contact pads has at least a concave portion filled with a filling material to prevent solder material from permeating along surfaces of the insulating protection layer and the electric contact pads, thereby eliminating the phenomenon of solder extrusion. Thus, bridging in the substrate structure can be eliminated even when the bump pitch between two adjacent electrical contact pads is small. As a result, short circuits can be prevented, and production yield can be increased.

  • Patent number: 10560012
    Abstract: A ZVS (zero voltage switching) control circuit for use in a flyback power converter includes a primary side controller and a secondary side controller. The primary side controller generates a switching signal to control a power transformer through a power transistor to generate an output voltage. The secondary side controller generates an SR (synchronous rectifier) signal to control an SR transistor at a secondary side of the power transformer. The SR signal includes an SR-control pulse and a ZVS pulse. The SR-control pulse controls the SR transistor according to a demagnetizing period of the power transformer. The ZVS pulse determines the starting timing of the switching signal to achieve zero voltage switching for the power transistor. The secondary side controller generates the ZVS pulse after a delay time from when the power transformer is demagnetized. The delay time is determined according to an output load of the output voltage.

  • Patent number: 10490475
    Abstract: In some embodiments, a semiconductor surface may be effectively passivated by nitridation, preferably using hydrazine, a hydrazine derivative, or a combination thereof. The surface may be the semiconductor surface of a transistor channel region. In some embodiments, native oxide is removed from the semiconductor surface and the surface is subsequently nitrided. In some other embodiments, a semiconductor surface oxide layer is formed at the semiconductor surface and the passivation is accomplished by forming a semiconductor oxynitride layer at the surface, with the nitridation contributing nitrogen to the surface oxide to form the oxynitride layer. The semiconductor oxide layer may be deposited by atomic layer deposition (ALD) and the nitridation may also be conducted as part of the ALD.
