The boot having skin-exfoliating means therein is a normal boot that when worn targets different regions of a foot and exfoliates dead skin from said regions of the foot, but in different exfoliating manners. The exfoliating means are designed to massage and exfoliate dead skin from the foot of an end user. The exfoliating means comprise massaging nodes aligned along a front, interior of the boot, which target skin between toes. Another exfoliating means is included along a middle region of the sole and includes an array of nodes that exfoliate skin along a bottom surface of the foot. Exfoliating ridges are located on two regions of the sole and are adapted to exfoliate skin at the rear of the foot and between the array of nodes and massaging nodes. Edge ridges adorn a periphery of the sole and provide additional exfoliating means.

A conductive structure configured to connect a contact pad of a semiconductor device with a corresponding contact pad of a substrate. The conductive structure includes two interconnectable members, one securable to each of the corresponding contact pads. Each member includes a dielectric jacket having an aperture that laterally confines conductive material of a conductive center thereof over the contact pad to which the member is secured. The conductive center of a female member of the conductive structure only partially fills the aperture of the jacket thereof so as to form a receptacle for an end of the male member of the conductive structure. One or both of the male and female members may also be configured to limit the insertion of the male member into the receptacle of the female member. The members of the conductive structure may be preformed structures which are attached to a surface of a semiconductor device or other substrate. Alternatively, the members can be fabricated on the surface of the semiconductor device or other substrate. A stereolithographic method of fabricating at least the jackets of the members is disclosed. The stereolithographic method may include use of a machine vision system including at least one camera operably associated with a computer controlling a stereolithographic application of material so that the system may recognize the position and orientation of a semiconductor device or other substrate on which a member of the conductive structure is to be fabricated. Methods of connecting a semiconductor device with another substrate are also disclosed, as are assemblies including the conductive structures.

Reinforced, self-aligning conductive structures for semiconductor device components and methods for fabricating same

A semiconductor device, semiconductor die package, mold tooling, and methods of fabricating the device and packages are provided. In one embodiment, the semiconductor device comprises a pair of semiconductor dies mounted on opposing sides of a flexible tape substrate, the outer surfaces of the dies having one or more standoffs disposed thereon. The standoffs can be brought into contact with an inner surface of the mold plates of a mold tooling when the device is positioned between the mold plates to maintain the flexible tape substrate in a centralized position within a mold chamber and inhibit the tape from bending as a molding compound flows into the chamber during encapsulation.

Methods for fabricating conductive structures on contact pads of semiconductor device components or other electronic components and for securing conductive structures to contact pads include directing consolidating energy toward unconsolidated conductive material. Alternatively, an unconsolidated material that will consolidate without additional consolidating energy may be used to form such conductive structures, in which case layers of the unconsolidated material are merely defined. Consolidating energy may be directed or layers of unconsolidated conductive material defined by recognizing the locations or orientations of one or more features, such as a contact, of the semiconductor device component or other electronic component. The conductive elements may include, but are not limited to, discrete conductive structures that protrude from the contacts, conductive traces that extend laterally from the contacts, or vias of circuit boards, interposers, or semiconductor devices.

An integrated circuit leadframe has a pair of leadframe rails that are specially treated to adhere to injection mold compounds to a lesser or greater degree than portions of the leadframe rails outside of the treated areas. By adhering to mold compounds to a greater degree, mold compound not removed during a deflashing procedure does not flake off to form mold compound debris during a trimming and forming procedure. By adhering to mold compounds to a lesser degree, substantially all of the mold compound is removed during the deflashing procedure so there is no mold compound to flake off to form mold compound debris during the trimming and forming procedure. The leadframe rails may be treated by forming apertures in the rails, by increasing or decreasing the roughness of the leadframe rails, or by coating the leadframe rails with an adhesion promoting or reducing material.

A stereolithographically fabricated heat sink may include non-linear, or convoluted passageways therethrough, through which air can flow. The heat sink may also include a heat dissipation element that is configured to release heat as air flows past a surface thereof. As at least a portion of the heat sink is stereolithographically fabricated, that portion can have a series of superimposed, contiguous, mutually adhered layers of thermally conductive material.

Heat sinks including nonlinear passageways

Programmed material consolidation processes for fabricating heat sinks include the selective consolidation of previously unconsolidated material. The heat dissipation element of the heat sink that has been fabricated by such processes can have non-linear or convoluted passageways therethrough to enhance air flow. An optical recognition system may be used in conjunction with programmed material consolidation processes to ensure that a heat sink is fabricated or positioned on the appropriate location of an electronic component, such as a semiconductor device.

Programmed material consolidation methods for fabricating heat sinks

Methods for fabricating semiconductor device components include use of programmed material consolidation processes to form the substrates or conductive elements thereof. The features that are formed by such processes may include multiple adjacent, mutually adhered regions. A machine vision system may be used so that the programmed material consolidation system may recognize the position, orientation, and features of a semiconductor device assembly, semiconductor die, or other substrate on which an element is to be fabricated.

An integrated circuit leadframe is specially adapted to adhere to injection mold cleaning compounds in the area of vents for an injection mold. An area of a leadframe rail that is normally positioned adjacent a mold vent is provided with apertures, surface roughness or a surface coating to cause the cleaning compound to more tightly adhere to the leadframe rail. As a result, cleaning compound flash is removed from the vents when the leadframe is removed from the mold.

A stereolithographically fabricated heat sink includes a heat transfer element cofigured to be disposed proximate a semiconductor device so as to absorb heat from the semiconductor device during use thereof. The heat sink also has a heat dissipation element that is configured to release heat as air flows past a surface thereof. When stereolithographic processes are used to fabricate the heat dissipation element of the heat sink, the heat dissipation element can have non-linear, or convoluted passageways formed therethrough, through which air can flow. As at least a portion of the heat sink is stereolithographically fabricated, that portion can have a series of superimposed, contiguous, mutually adhered layers of thermally conductive material. The layers can be fabricated by consolidated selected regions of a layer of unconsolidated particulate or powdered material, or by defining an object layer from a sheet of material. The stereolithographic method may include use of a machine vision system including at least one camera operably associated with a computer controlling a stereolithographic application of material so that the system may recognize the position and orientation of a semiconductor device or other substrate on which the heat sink is to be fabricated.

Selectively consolidated conductive elements. The conductive elements may include multiple, mutually adhered regions that comprise conductive material, such as a thermoplastic conductive elastomer or a metal. In semiconductor device assemblies, the conductive elements may electrically connect contacts of semiconductor device components to one another. The conductive elements may alternatively comprise conductive traces or vias of circuit boards or interposers. Selective consolidation processes may be employed to fabricate the conductive elements. Such processes may include use of a machine vision system with at least one camera operably associated with a computer controlling consolidation or application of material so that the system may recognize the position, orientation, and features of a semiconductor device assembly, semiconductor die, or other substrate on which the conductive element is to be fabricated.

A method and apparatus for reducing or eliminating the formation of air pockets or voids in a flowable material provided in contact with at least one substrate. The flowable material is provided in a non-horizontal direction and flows from a lower portion to an upper portion. As a result, the flowable material is provided uniformly with a single, uniform flow front due to gravity acting thereon and gravity thereby substantially preventing voids and air pockets from forming in the flowable material. In one embodiment, the at least one substrate is provided in the cavity of a transfer mold in which the cavity is filled from a gate at a lower portion of the cavity to a vent at an upper portion of the cavity. In another embodiment, a bumped semiconductor device is attached to a substrate having a gap therebetween, in which the gap is oriented longitudinally perpendicular to a horizontal plane so that the flowable material may fill the gap in a vertical direction.
