Patent number: 7405487Abstract: A method and apparatus for encapsulating microelectronic devices. In one embodiment, the method includes removing a portion of encapsulating material that at least partially surrounds a microelectronic substrate by directing a source of laser radiation toward the encapsulating material. The method can further include exposing a surface of the microelectronic substrate, for example, to enhance a rate at which heat is transferred away from the microelectronic substrate. Alternatively, the encapsulating material can be removed to form heat transfer structures, such as pins or ribs, also to enhance a rate at which heat is transferred away from the microelectronic substrate. In still another embodiment, a portion of the encapsulating material or a support member to which the substrate is attached can be removed to define interlocking features that allow one microelectronic substrate package to be stacked on another and to resist relative movement between the two packages.Type: GrantFiled: August 12, 2002Date of Patent: July 29, 2008Assignee: Micron Technology, Inc.Inventor: Joseph M.

Patent number: 7067905Abstract: The present invention is directed toward methods and apparatuses for encapsulating a microelectronic die or another type of microelectronic device. One aspect of the present invention is directed toward packaging a microelectronic die that is attached to either a first surface or a second surface of a substrate. The die can be encapsulated by positioning the die in a cavity of a substrate and sealing the substrate to the substrate. The method can further include injecting an encapsulation compound into the cavity at a first end of the substrate to move along the first surface of the substrate. This portion of the compound defines a first flow of compound along the first surface that moves in a first direction from a first end of the substrate toward a second end of the substrate.Type: GrantFiled: August 8, 2002Date of Patent: June 27, 2006Assignee: Micron Technology, Inc.Inventor: Joseph M.

Patent number: 6706560Abstract: Methods for applying a heat sink to a semiconductor chip. A heat sink frame is removably attached to one or more heat sinks and is used to align the heat sinks with corresponding semiconductor chips. The semiconductor chips are preferably positioned on a semiconductor chip frame.

The heat sink frame is detached from the heat sinks at a selected time after the heat sinks and the semiconductor chips have been aligned, whereby the heat sinks remain combined with the semiconductor chips. Detachment of the heat sink frame may be conducted before or, alternatively, after the semiconductor chips have been encapsulated. The methods of the invention facilitates the efficient and reliable application of heat sinks to semiconductor chips.Type: GrantFiled: March 8, 2002Date of Patent: March 16, 2004Assignee: Micron Technology, Inc.Inventor: Joseph M.
