标 题 :Near-room temperature CVD synthesis of organic polymer/oxide dielectric nanocomposites

摘要:Nanocomposite thin films with low dielectric constants are made by the simultaneous deposition of an oxide dielectric and an organic polymer at near room temperatures. Suitable oxides include SiO 2 , and suitable organic polymers include poly(chloro-para-xylylene). The two dielectric materials, when deposited, form nanocomposites characterized by nanometer-sized domains of dielectric material. The nanocomposite thin films of this invention are useful as dielectric layers for interlevel dielectric (ILD) and intermetal dielectric (IMD) dielectrics in the manufacture of semiconductor devices as well as for thin films for flat panel displays, food wraps, hybrid ceramics, glass, hard disk drives, and optical disk drives. Additionally, the invention comprises semiconductor devices and semiconductor chips made incorporating nanocomposites deposited by chemical vapor deposition.

摘要:The present application discloses a method of forming an inorganic macroporous material. In some embodiments, the method includes: providing a sample of organic polymer particles having a particle size distribution of no greater than about 10%; forming a colloidal crystal template of the sample of organic polymer particles, the colloidal crystal template including a plurality of organic polymer particles and interstitial spaces therebetween; adding an inorganic precursor composition including a noncolloidal inorganic precursor to the colloidal crystal template such that the precursor composition permeates the interstitial spaces between the organic polymer particles; converting the noncolloidal inorganic precursor to a hardened inorganic framework; and removing the colloidal crystal template from the hardened inorganic framework to form a macroporous material. Inorganic macroporous materials are also disclosed.

标 题 :Method for producing elastomeric copolyesters

摘要:A process for continuous or discontinuous synthesis of elastomeric copolyesters from polybutylene terephthalate (PBT) and polyoxytetramethylene glycol is described in which the tetrahydrofuran (THF) obtained as a byproduct in synthesis of polybutylene terephthalate from 1,4-butanediol is rectified and then reacted by ring-opening polymerization to form polyoxytetramethylene glycol which condenses with the free or esterified carboxyl groups of PBT to form the copolyester, whereby chain termination and catalyst deactivation are accomplished by adding 1,4-butanediol without separating the catalyst.

摘要:A solvothermal process for making inorganic nanoparticles is described. Inorganic nanoparticles can be produced by forming a suspension or solution comprising at least one group II-IV and lanthanide metal inorganic salt in a first medium, disposing the suspension or solution in a sealed chamber having an interior pressure, elevating the interior pressure of the sealed chamber to an initial interior pressure prior to the heating, heating the suspension or solution to a peak temperature higher than the normal boiling point of the first medium, optionally adding a second medium to the suspension or solution after the heating.

摘要:The present invention relates to molecular sieve compositions and a process to synthesize such compositions. More particularly, this invention relates to a catalyst composition with metal oxide deposited on the exterior surface of the molecular sieve particles. The metal oxide can be deposited by contacting the molecular sieve particles with a solution of a metal-containing salt and a solvent, the metal-containing salt solution having an anion size larger than the pore size of the molecular sieve particles. The molecular sieve particles can then be dried and then treated under conditions sufficient to form a metal oxide, whereby at least a portion of the metal-containing salt can be converted to metal oxide.

摘要:A system, apparatus and method are provided for processing articles. The system includes subsystems for synthesizing, pre-treating, conducting a vapor phase coating process and post-treating articles in the form of powders and solid or porous workpieces. The apparatus permits vapor phase synthesis, treatment and deposition processes to be performed with high efficiency and at high overall throughput. The methods include converting solids, liquids or gases into gaseous and solid streams that can be separated or exchanged with or without treatment and/or coating steps, and produce optimized composite articles for specific applications.
