Semiconductor package having wettable lead flank and method of making the same
A semiconductor package comprises a lead frame, a chip, and a molding encapsulation. The lead frame comprises one or more die paddles, a first plurality of leads, and a second plurality of leads. A respective end surface of each lead of the first plurality of leads and the second plurality of leads is plated with a metal. A first respective window on a first side of each lead of the first plurality of leads and the second plurality of leads is not plated with the metal. A second respective window on a second side of each lead of the first plurality of leads and the second plurality of leads is not plated with the metal. A method for fabricating a semiconductor package comprises the steps of providing a lead frame array, mounting a chip, forming a molding encapsulation, and applying a cutting process or a punching process.
SEMICONDUCTOR PACKAGE WITH RAISED DAM ON CLIP OR LEADFRAME
A semiconductor package includes a semiconductor die including circuitry electrically coupled to bond pads that is mounted onto a leadframe. The leadframe includes a plurality of leads and a dam bar having a transverse portion that extends between adjoining ones of the leads. The bond pads are electrically connected to the plurality of leads. A raised dam pattern is on the dam bar or on an edge of an exposed portion of a top side clip of the semiconductor package that is positioned above and connects to the semiconductor die. The raised dam pattern includes a first material that is different relative to the material of the dam bar or the clip. A mold material encapsulates the semiconductor die.
Plurality of leads between MOSFET chips
A semiconductor device includes: a first chip including first and second electrodes provided at a first surface, and a third electrode provided at a second surface positioned at a side opposite to the first surface; a second chip including fourth and fifth electrodes provided at a third surface, and a sixth electrode provided at a fourth surface positioned at a side opposite to the third surface, wherein the second chip is disposed to cause the third surface to face the first surface; a first connector disposed between the first electrode and the fourth electrode and connected to the first and fourth electrodes; and a second connector disposed between the second electrode and the fifth electrode and connected to the second and fifth electrodes.
SEMICONDUCTOR DEVICE
In a semiconductor device, a thinly-molded portion covering a whole of a heat dissipating surface portion of a lead frame and a die pad space filled portion are integrally molded from a second mold resin, because of which adhesion between the thinly-molded portion and lead frame improves owing to the die pad space filled portion adhering to a side surface of the lead frame. Also, as the thinly-molded portion is partially thicker owing to the die pad space filled portion, strength of the thinly-molded portion increases, and a deficiency or cracking is unlikely to occur.

Semiconductor device and method of forming micro interconnect structures
A semiconductor device has a first semiconductor die and second semiconductor die with a conductive layer formed over the first semiconductor die and second semiconductor die. The second semiconductor die is disposed adjacent to the first semiconductor die with a side surface and the conductive layer of the first semiconductor die contacting a side surface and the conductive layer of the second semiconductor die. An interconnect, such as a conductive material, is formed across a junction between the conductive layers of the first and second semiconductor die. The conductive layer may extend down the side surface of the first semiconductor die and further down the side surface of the second semiconductor die. An extension of the side surface of the first semiconductor die can interlock with a recess of the side surface of the second semiconductor die. The conductive layer extends over the extension and into the recess.
Semiconductor device and method for manufacturing semiconductor device
A semiconductor device A1 disclosed includes: a semiconductor element 10 having an element obverse face and element reverse face that face oppositely in a thickness direction z, with an obverse-face electrode 11 (first electrode 111) and a reverse-face electrode 12 respectively formed on the element obverse face and the element reverse face; a conductive member 22A opposing the element reverse face and conductively bonded to the reverse-face electrode 12; a conductive member 22B spaced apart from the conductive member 22A and electrically connected to the obverse-face electrode 11; and a lead member 51 having a lead obverse face 51a facing in the same direction as the element obverse face and connecting the obverse-face electrode 11 and the conductive member 22B. The lead member 51, bonded to the obverse-face electrode 11 via a lead bonding layer 321, includes a protrusion 521 protruding in the thickness direction z from the lead obverse face 51a. The protrusion 521 overlaps with the obverse-face electrode 11 as viewed in the thickness direction z. This configuration suppresses deformation of the connecting member to be pressed during sintering treatment.
