Abstract: A microelectronic assembly includes a substrate and a first microelectronic component mounted on the substrate. The first microelectronic component includes a digital/analog IP block and a RF IP block. A shielding case is mounted on the substrate. The shielding case includes a plurality of sidewalls, one intermediate wall, and a lid. A thermal interface material (TIM) layer is situated between the lid and the first microelectronic component. A noise suppressing structure is interposed between the TIM layer and the first microelectronic component.

Abstract: The invention provides a semiconductor package assembly. The semiconductor package assembly includes a substrate, a semiconductor die, a base and a first inductor structure. The substrate has a die-attach surface and a solder-ball-attach surface opposite to the die-attach surface. The semiconductor die is mounted on the die-attach surface of the substrate. The semiconductor die includes a radio-frequency (RF) circuit and a first RF die pad electrically connected to the RF circuit. The base is mounted on the solder-ball-attach surface of the substrate. The first inductor structure is positioned on the substrate, the semiconductor die or the base. The first inductor structure includes a first terminal electrically connected to the first die pad and a second terminal electrically connected to a ground terminal.

Abstract: A Radio Frequency (RF) device may include a plurality of antennas and one or more conductive traces configured to trap a portion of energy transmitted from at least one of the plurality of antennas. The one or more conductive traces are sized and positioned such that undesired coupling between the plurality of antennas may be suppressed while maintaining performance parameters of at least one of the plurality of antennas. The plurality of antennas and the one or more conductive traces may be formed using a redistribution layer coupled to a chip embedded in a molding layer.

Abstract: A semiconductor package structure is provided. The semiconductor package structure includes a package substrate. An integrated circuit (IC) die having a radio frequency (RF) circuit and a memory die are stacked over the package substrate. The memory die entirely covers a first surface portion of the package substrate to define a second surface portion of the package substrate exposed from the memory die, and the IC die partially covers the first surface portion and the second surface portion of the package substrate. The RF circuit includes a first sensitive device region corresponding to the second surface portion of the package substrate and a second sensitive device region corresponding to the first surface portion of the package substrate and offsetting a memory input/output (I/O) electrical path of the memory die, as viewed from a top-view perspective.

Abstract: A waterproof paint formula and a pen device for using the same. The concentration of the formula may be adjusted by changing the weight percentage of the aqueous solution and cooperate with different outlet diameter of the nibs to make the waterproof paint smoothly flow out for painting on the writings. Simultaneously, the weight percentage of Ethyl Alcohol may be adjusted to control the air-dried speed of the waterproof paint to achieve the effects of waterproof and preventing the inks or colors from diffusion.
