摘要:
An electrical interconnect device attaches electrical devices with a cantilever spring with out the use of solder or adhesive. The cantilever spring latches to a contact structure such that there are a plurality of contact points between the spring and the contact structure. The cantilever spring has two tines at a tip end that define an opening in the spring. The contact structure is received by the opening between the two tines so that the spring and the contact structure mate. The spring may engage the contact structure by latching to the contact structure or by a post that urges the tip end of the spring against the contact structure.

A print structure includes a pattern layer that selectively actuates one or more of a plurality of actuators to selectively form one or more wells in a print surface to create a defined pattern on the print surface. A material is applied to the one or more wells and subsequently transferred to another surface in order to transfer the pattern.

A socket for solderless connection between a stud-bumped IC chip and a host PCB. The socket includes a three-dimensional (e.g., cylindrical or cubical) hollow metal frame that is either free-standing or supported by an underlying patterned template structure. The metal frame includes side walls that extend away from the host PCB, and a contact structure located at the upper (i.e., free) end of the side walls. The contact structure defines an opening through which a stud bump can be inserted into a central chamber of the metal frame. The side walls and/or the contact structure are formed such that when the tip end of the stud bump is inserted into the central chamber, at least one of the base structure and the sidewall of the stud bump abuts the contact structure at two or more contact points.

Various structures, such as microstructures and wall-like structures, can include parts or surfaces that are oblique. In some implementations, a cantilevered element includes a spring-like portion with a uniformly oblique surface or with another artifact of an oblique radiation technique. In some implementations, when a deflecting force is applied, a spring-like portion can provide deflection and spring force within required ranges. Various oblique radiation techniques can be used, such as radiation of a layer through a prism, and structures having spring-like portions with oblique radiation artifacts can be used in various applications, such as with downward or upward deflecting forces.

A spring contact has a post-release outer upper surface in compression and a post-release outer lower surface in compression. A compressive lower layer of spring material may be formed at a thickness that is three-eighths or less of a tensile upper layer of spring material. A low modulus of elasticity cladding material may also be applied to the outer surface of the spring contact with a lower surface of the cladding material being formed with a compressive stress.

Photovoltaic devices (i.e., solar cells) are formed using non-contact patterning apparatus (e.g., a laser-based patterning systems) to define contact openings through a passivation layer, and direct-write metallization apparatus (e.g., an inkjet-type printing or extrusion-type deposition apparatus) to deposit metallization into the contact openings and over the passivation surface. The metallization includes two portions: a contact (e.g., silicide-producing) material is deposited into the contact openings, then a highly conductive metal is deposited on the contact material and between the contact holes. The device wafers are transported between the patterning and metallization apparatus in hard tooled registration using a conveyor mechanism. Optional sensors are utilized to align the patterning and metallization apparatus to the contact openings. An extrusion-type apparatus is used to form grid lines having a high aspect central metal line that is supported on each side by a transparent material.
摘要:
A method of forming a self-assembled interconnect structure is described. In the method, a contact pad surface and particles in a solution are brought together. The particles are selected such that they the particles adhere to the contact pad surface. Formation of a contact is completed by pressing an opposite contact into the particles such that an electrical connection is formed via the particles between the opposite contact pad and the substrate surface contact pad. The described self-assembled interconnect structure is particularly useful in display device fabrication.

摘要:
A data transmission interconnect assembly capable of transmission speeds in excess of 40 Gbps in which, for example, a line-card is detachably coupled to a backplane using flexible flat cables that are bent to provide a continuous, smooth curve between the connected boards, and connected by a connection apparatus that employs cable-to-cable interface members that are transparent to the transmitted signal waves. Microspring interface members are formed on the contact structure pressed against the cables to provide interface arrangements that are smaller than a wavelength of the transmitted signal. A connector apparatus uses a cam mechanism to align the cables, and then to press the contact structure, having the microspring interface members formed thereon, against the cables. An alterative contact structure uses anisotropic conductive film.
摘要:
A structure has at least one structure component formed of a first material residing on a substrate, such that the structure is out of a plane of the substrate. A first coating of a second material then coats the structure. A second coating of a non-oxidizing material coats the structure at a thickness less than a thickness of the second material.
