摘要:
An interposer, interposer package and device assembly employing the same are provided. The interposer has a substrate formed of a semiconductor material, with first input/output contacts disposed over a first main surface thereof and second input/output contacts disposed over a second main surface thereof. The second input/output contacts are electrically connected to the first input/output contacts. The first input/output contacts disposed over the first main surface of the interposer substrate are for attachment to input/output pads of a device to which the interposer is to be attached. The second input/output contacts disposed over the second main surface of the interposer substrate facilitate electrical coupling to a component to which the interposer is also to be attached.

A storage cell includes a first bit line, a storage circuit, and a pass transistor. The storage circuit has a first storage node for holding a logic state indicative of a logic value. The pass transistor is coupled to the first bit line and the first storage node for establishing a conduction path therebetween. The pass transistor receives a bias voltage to switch the pass transistor into a substantially nonconducting state when the storage cell is not being accessed. The reverse bias on the first transistor substantially reduces the leakage current through the pass transistor.

Chip adhesives with improved working time comprise a polyetherimide prepared from 2,2-bis[4-(3,4-dicarboxyphenoxy)phenyl]propane dianhydride and bis(4-aminophenyl) sulfone; at least one of silica and conductive metal particles, especially silver particles; and at least one substituted acetophenone as solvent. The preferred substituted acetophenone is 4-methylacetophenone.

The present invention is a software product that provides merchants that sell time-slot inventories tools to capitalize on the Internet revolution. The present invention enables the creation of web-sites for merchants with a built-in web-based reservation booking system. This offers customers the on-line benefits of access, selection and immediacy in making real-time reservation/appointments over the Internet. The software product also simplifies the merchant's booking process by providing a central web-based reservation/appointment management system that can be used for all bookings, regardless if made by telephone, by a walk-in customer, or by a customer via the Internet. The software product also provides the merchant with a powerful direct marketing tool. As a merchant uses the software product, user-customer profiles and demographics are captured in the database module, thus creating (in Web jargon) a “community” of customers specific to the merchant. The merchant is thus empowered, using the mail module, to directly communicate with its customer base, using customer profiles and demographics to create a highly targeted and effective marketing and promotional ad campaign. The software product also allows the merchant to auction off time-slot inventory over the Internet. Lastly, the software product enables the creation of Web “super-communities” consisting of the aggregate of all the individual merchant's customer-communities using the software product.

A method for the preparation a photo-mask used for photo-imaging selected areas on the surfaces of a three-dimensional printed circuit board substrate. The photo-mask comprises a membrane transparent and degradation resistant to UV light, having at least one side with a contoured shape conforming, and flexible enough to comply with surface irregularities on the surfaces of the three-dimensional substrate being photo-imaged. A pattern of tracks opaque to UV light is posiitoned along the contoured shape of the membrane. The pattern of tracks on the photo-mask is in accordance with a desired conductive metal trace pattern on the surfaces of the three-dimensional printed circuit board substrate. The photo-mask is prepared by photo-imaging and then depositing a track material on a film that conformed to the surfaces of the three-dimensional substrate. An adhesive layer applied over the film cements a membrane material poured upon the adhesive layer. Once the membrane material sets into the membrane it is sepaarated from the substrate to form the photo-mask of the present invention.
摘要:
Selective electrolytic deposition on either conductive or non-conductive bodies is provided by forming a layer of a metal which forms a plating-preventing compound on the surface of the body to be plated, and selectively interdiffusing a plating-enabling metal into the surface of that compound-forming metal in those locations where plating is desired and electroplating the body. The interdiffusion may be done before or after the plating-preventing compound has formed on the surface of the compound-forming layer. During the electroplating, the electroplating metal deposits only in those locations where the plating-enabling metal has interdiffused with the compound-forming metal. At the end of the process, the compound-forming metal may be removed in those locations where it is not covered by the electroplated metal to provide a plurality of separate plated conductors.

A disposable plastic bottle that includes a receptacle formed in a plastic casing having an outside surface and an inside surface that defines a volume for holding a beverage. The receptacle includes (a) an internal seal that protrudes inward from the inside surface of the plastic casing into the volume for holding the beverage and (b) an external surface that is substantially flush or protrudes slightly outward from the outside surface of the plastic casing and that is exposed through the plastic casing and configured to directly receive an external pressure.
摘要:
A high frequency electronic component which is interconnected with other components through a high density interconnect structure sees only an air dielectric constant in the high density interconnect structure because a spacer structure disposed on the electronic component spaces the dielectric of the high density interconnect structure from the surface of the electronic component by a sufficient distance that the higher dielectric constant of the polymer dielectric layers of the high density interconnect structure only minimally affects the operating characteristics of the electronic components.
摘要:
A high density interconnect structure incorporating a plurality of laminated dieletric layers is fabricated using thermoplastic adhesive layers of progressively lower glass transition temperature in order to maintain the stability of the already fabricated structure during the addition of the later laminations. This structure also facilitates the removal of only a portion of the high density interconnect structure where a fault in the system can be corrected in one of the upper layers of the high density interconnect structure.
