A package stack may include a first package and a second package. The first package may have an IC chip with an active surface and a back surface. The active surface may be connected to a first major surface of a first circuit substrate. The second package may include a second IC chip with an active surface and a back surface. The back surface of the second IC chip may be attached to a first major surface of a second circuit substrate and the active surface of the second IC chip may be electrically connected to the first major surface of the second circuit substrate. The first package may be stacked on the second package so that the active surface of the second package may be electrically connected to a second major surface of the first circuit substrate of the first package. A method may involve providing a first package having a first IC chip and a first circuit substrate and providing a second package having a second IC chip and a second circuit substrate. The first and the second packages may be stacked so that the active surface of the second IC may face and be electrically connected to a major surface of the first circuit substrate.

A lead frame unit, a semiconductor package having a lead frame unit, a stacked semiconductor package having a semiconductor package, and methods of manufacturing the same are provided. The lead frame unit in a stacked semiconductor package may include a die pad supporting a semiconductor chip, an inner lead electrically connected to the semiconductor chip, an outer lead extending from the inner lead, and a heat-resistant insulation member surrounding the connection portion. The outer lead may include a connection portion connected to the inner lead and a junction portion connected to the connection portion and a circuit board. An external signal may be applied to the junction portion. If the lead frame unit is used in the stacked semiconductor package, the outer lead and a dummy outer lead in the stacked semiconductor package may have substantially the same shape.

A method of processing a semiconductor wafer that has a first surface and a second surface opposite to the first surface. The method includes forming grooves of a predetermined depth on the second surface on which circuit patterns are formed, attaching a first surface of a protective tape to the second surface on which the grooves are formed, attaching a carrier tape to a second surface of the protective tape opposite to the first surface of the protective tape so that the first surface of the semiconductor wafer can be oriented upward, removing the first surface of the semiconductor wafer by a predetermined thickness and dividing the semiconductor wafer into chips by the grooves, and supplying each chip to a die bonder in the state where the first surface of the of the chip is oriented upward. Only one kind of die bonder is needed. A UV-type tape is not required.

A semiconductor device includes a semiconductor package, a circuit board and an interval maintaining member. The semiconductor package has a body and a lead protruded from the body. The circuit board has a first land electrically connected to the lead. The interval maintaining member is interposed between the circuit board and the body. The interval maintaining member maintains an interval between the lead and the first land. Thus, an interval between the lead and the land is uniformly maintained, so that a thermal and/or mechanical reliability of the semiconductor device is improved.

The present invention relates to an insert block for testing semiconductor devices. The insert block comprises one or more pushers, installed in a block body having a loading space to accommodate a semiconductor device under test, including a first push rod to apply force to one of adjacent sides of the semiconductor device under test and a second push rod to apply force to the other thereof.Accordingly, firm centering of semiconductor devices under test relative to the contact pins of the test socket along the two perpendicular axes (for instance, x and y axes) on the top or bottom surface of the semiconductor device is achieved and leads to the proper interfaces between the external terminals of the semiconductor device under test and the contact pins of the test socket, and thereby improves the quality of connection therebetween.
