  • Patent number: 11201096
    Abstract: A die-wrapped packaged device includes at least one flexible substrate having a top side and a bottom side that has lead terminals, where the top side has outer positioned die bonding features coupled by traces to through-vias that couple through a thickness of the flexible substrate to the lead terminals. At least one die includes a substrate having a back side and a topside semiconductor surface including circuitry thereon having nodes coupled to bond pads. One of the sides of the die is mounted on the top side of the flexible circuit, and the flexible substrate has a sufficient length relative to the die so that the flexible substrate wraps to extend over at least two sidewalls of the die onto the top side of the flexible substrate so that the die bonding features contact the bond pads.

  • Publication number: 20210375731
    Abstract: A microelectronic device has a die with a first electrically conductive pillar, and a second electrically conductive pillar, mechanically coupled to the die. The microelectronic device includes a first electrically conductive extended head electrically coupled to the first pillar, and a second electrically conductive extended head electrically coupled to the second pillar. The first pillar and the second pillar have equal compositions of electrically conductive material, as a result of being formed concurrently. Similarly, the first extended head and the second extended head have equal compositions of electrically conductive material, as a result of being formed concurrently. The first extended head provides a bump pad, and the second extended head provides at least a portion of a first plate of an integrated capacitor. A second plate may be located in the die, between the first plate and the die, or on an opposite of the first plate from the die.

  • Publication number: 20210345495
    Abstract: A microelectronic device includes a die less than 300 microns thick, and an interface tile. Die attach leads on the interface tile are electrically coupled to die terminals on the die through interface bonds. The microelectronic device includes an interposer between the die and the interface tile. Lateral perimeters of the die, the interposer, and the interface tile are aligned with each other. The microelectronic device may be formed by forming the interface bonds and an interposer layer, while the die is part of a wafer and the interface tile is part of an interface lamina. Kerfs are formed through the interface lamina, through the interposer, and partway through the wafer, around a lateral perimeter of the die. Material is subsequently removed at a back surface of the die to the kerfs, so that a thickness of the die is less than 300 microns.

  • Patent number: 11152322
    Abstract: In one instance, a method of forming a semiconductor package with a leadframe includes cutting, such as with a laser, a first side of a metal strip to a depth D1 according to a cutting pattern to form a first plurality of openings, which may be curvilinear. The method further includes etching the second side of the metal strip to a depth D2 according to a photoresist pattern to form a second plurality of openings. At least some of the first plurality of openings are in fluid communication with at least some of the second plurality of openings to form a plurality of leadframe leads. The depth D1 is shallower than a height H of the metal strip, and the depth D2 is also shallower than the height H. Other embodiments are presented.
