Abstract: A chip-on-wafer-on-substrate (CoWoS) semiconductor assembly is formed which includes a chip-on-wafer (CoW) sub-assembly of integrated circuit (IC) dies mounted on an interposer, which is in turn mounted on a package substrate with a top metallization stack and a bottom metallization stack using bonding bumps connecting the backside of the interposer and the front side of the package substrate. The bonding bumps provide electrical connections between the ends of through-vias exposed at the backside of the interposer and the top metallization stack of the package substrate. The likelihood of certain failure mechanisms that can adversely affect CoWoS yield are reduced or eliminated by ensuring a total metal thickness of the top metallization stack is greater than a total metal thickness of the bottom metallization stack, but not so much greater as to induce cracking of the underfill material during curing thereof.

Abstract: A heat dissipation device includes a vapor chamber for contacting a heat source; at least one heat pipe having a first end and a second end connected to the vapor chamber; at least one partition disposed inside the heat pipe to partition the inside of the heat pipe into a first channel and a second channel isolated from each other; and a heat dissipation fin set disposed on the vapor chamber and partially covers the heat pipe. The vapor chamber is filled with a liquid working medium that absorbs the heat of the heat source and then gasifies into a gaseous working medium. The gaseous working medium moves into the first channel and the second channel to be condensed by the heat dissipation fin set, so the gaseous working medium is liquefied into the liquid working medium, and then the liquid working medium flows back into the vapor chamber.

Abstract: A method of designing a device includes identifying a pin to be inserted into a first layer of the device, wherein the first layer has a plurality of first routing tracks, and each of the plurality of first routing tracks extend in a first direction. The method further includes identifying a blocking shape on a second layer different from the first layer, wherein the second layer has a plurality of second routing tracks, and each of the plurality of second routing tracks extends in a second direction different from the first direction. The method further includes determining at least one candidate location for the pin in the first layer based on the plurality of first routing tracks of the first layer. The method further includes setting a location for the pin in the first layer based on the determined at least one candidate location.

Abstract: An electrocardiogram (ECG) detection module with longer service life includes an ECG detection device, the ECG detection device includes a conductive adhesive film, and a support member. Bioelectric signals of both hands of a driver/user are obtained by the conductive adhesive film arranged on a surface of the steering wheel. The support member is elastic and arranged between the steering wheel and the conductive adhesive film. The support member causes the conductive adhesive film to adhere to the contours of the steering wheel, and the support member further increases and enlarges area of contact between the conductive adhesive film and the hand of the user. The present disclosure also provides a steering wheel incorporating the detection module.

Abstract: A dehydrogenation method for hydrogen storage materials, which is executed by a fuel cell system. The fuel cell system includes a hydrogen storage material tank, a heating unit, a fuel cell, a pump, a water thermal management unit and a heat recovery unit. The described dehydrogenation method utilizes the heating unit and the heat recovery unit to provide thermal energy to the hydrogen storage material tank, so that hydrogen storage material is heated to the dehydrogenation temperature. The pump extracts hydrogen from the hydrogen storage material tank, so that the hydrogen storage material is under negative pressure (i.e. H2 absolute pressure below 1 atm), according to which the hydrogen storage material is dehydrogenated, and the dehydrogenation efficiency and the amount of hydrogen release are improved. The method n can reduce the dehydrogenation temperature of the hydrogen storage material, and reduce the thermal energy consumption for heating the hydrogen storage material.
