Single package wireless communication device
View Patent ↗An integrated circuit package includes a substrate, first, second and third dies and an antenna. The substrate includes a first layer with electrical traces and a second layer substantially formed of a dielectric material. The first die includes a first integrated circuit. The second die includes a second integrated circuit electrically coupled through wire bonds to the integrated circuit on the substrate and mechanically coupled to the first die such that the first die is disposed between the substrate and the second die. The third die includes a third integrated circuit and is electrically coupled to the integrated circuit on the substrate. The antenna and the first, second and third integrated circuits substantially form a radio transceiver.
1. An integrated circuit package comprising:
a substrate including a first layer with electrical traces that partially form an integrated circuit on the substrate and a second layer substantially formed of dielectric material;
a first plurality of solder regions at a bottom of the second layer, each region having a cross-sectional area less than a first particular value;
a second plurality of solder regions at the bottom of the second layer to provide grounding for a radio transceiver, each region having a cross-sectional area of a value that is different than the first particular value;
a first die, including a first integrated circuit, with an array of solder bumps on a first side of the die wherein the solder bumps couple the first integrated circuit to the substrate;
a second die, including a second integrated circuit electrically coupled through wire bonds to the integrated circuit on the substrate, mechanically coupled to a second side of the first die that is substantially parallel to the first side of the first die, such that the first die is disposed between the substrate and the second die an antenna electrically coupled to the integrated circuit on the substrate;
a third die, including a third integrated circuit, electrically coupled to the second integrated circuit by means of an array of solder bumps, wherein the antenna and the first, the second and the third integrated circuits substantially form the radio transceiver; and
the value of each of the second plurality of solder regions after reflow exceeds the first particular value when the substrate is soldered on a printed circuit board.
2. The integrated circuit package of claim 1 wherein the second integrated circuit further comprises a base band communication processor.
3. The integrated circuit package of claim 1 further comprising
the third die, including the third integrated circuit forming a memory device, electrically coupled to the second integrated circuit through the respective solder bumps that connect an active side of the third die to an active side of the second die.
4. The integrated circuit package of claim 1 wherein the first integrated circuit further comprises a radio frequency integrated circuit and a mixed signal processor.
5. The integrated circuit package of claim 1 wherein the radio frequency transceiver is capable of communicating according to a wireless standard used substantially for a selected one of the group consisting of a personal area network, a local area network, a metropolitan area network, a wide area network, and a combination thereof.
6. The integrated circuit package of claim 1 , wherein the third die is formed substantially of a selected one chosen from the group consisting of gallium arsenide, silicon on sapphire, and silicon germanium.
