Interconnect structures possessing an organosilicate glass interlayer dielectric material with minimal stoichiometeric modification and optionally an intact organic adhesion promoter for use in semiconductor devices are provided herein. The interconnect structure is capable of delivering improved device performance, functionality and reliability owing to the reduced effective dielectric constant of the stack compared with that of those conventionally employed because of the use of a sacrificial polymeric material deposited onto the dielectric and optional organic adhesion promoter during the barrier open step done prior to ashing the patterning material. This sacrificial film protects the dielectric and optional organic adhesion promoter from modification / consumption during the subsequent ashing step during which the polymeric film is removed.

A composite membrane is provided having a first layer and a second layer, the first layer comprising an alginic acid or a salt of alginic acid, or a salt of a derivative of an alginic acid, and the second layer comprising a non-porous polymer with at least one hydrophilic functional group and adapted to provide mechanical support and reinforcement of the first layer. The second layer is selectively water permeable and can comprise water insoluble polymers such as chitosan, chitosan derivatives and cellulose derivatives. The second layer can also comprise water soluble polymers so long as such polymers are adequately crosslinked. Where the second layer comprises chitosan, each of the alginic acid or the salt of an alginic acid or the salt of a derivative of an alginic acid of the first layer and the chitosan of the second layer can be crosslinked separately by immersing in a formaldehyde solution.

The ratio of the thickness of the first layer to the second layer is from about 1:1 to 1:5.

A monopole acoustic transmitter for logging-while-drilling comprising as a ring that comprises one or more piezoelectric arc segments. The ring is oriented in a plane whose normal is essentially coincident with the major axis of a logging tool in which it is disposed.

The ring can comprise a continuous ring of piezoelectric material, or alternately arc segments or active ring segments of piezoelectric ceramic bonded to segments of other materials such as alumina to increase the frequency or heavy metals such as tungsten to reduce the frequency. The material and dimensions of the material used in-between the piezoelectric segments is chosen to alter the frequency of the ring.

Embodiments of the present invention are directed to a process for forming small diameter vias at low temperatures. In preferred embodiments, through-substrate vias are fabricated by forming a through-substrate via; and depositing conductive material into the via by means of a flowing solution plating technique, wherein the conductive material releases a gas that pushes the conductive material through the via to facilitate plating the via with the conductive material. In preferred embodiments, the fabrication of the substrate is conducted at low temperatures.
