Patent number: 6114227Abstract: This invention relates to the design of apparatus for processing electronic devices, including equipment for chemical vapor deposition or transport polymerization. The new designs of gas separator plates, their configuration, and the regulation of gas flows through the system provides control over the pattern of precursor gas flow away from the separation plates, thereby decreasing the amount of byproducts that are deposited on the plates and throughout the reactor. New designs for shaping other surfaces of the dispersion head reduces contamination of those elements, and new designs for chamber panels decrease the deposition of byproducts on those surfaces, as well as other elements of the reactor. Decreasing deposition of byproducts increases the amount and the quality of the film that can be deposited without requiring the system to be shut down for cleaning.Type: GrantFiled: March 29, 1999Date of Patent: September 5, 2000Assignee: Quester Technology, Inc.Inventors: David Leksell, Ming Xi Chan, Joseph P.

Patent number: 6086679Abstract: The described deposition systems are designed to accommodate new precursors and chemical processes used for transport polymerization and chemical vapor deposition. The systems consist primarily of a reactor, a liquid injector or gas mass flow controller, a cracker and a deposition chamber under sub-atmospheres pressure. The cracker utilizes one or more types of energy, including heat, photons, and plasmas. This invention is especially useful for preparing F-PPX (fluorinated poly(para-xylylenes) and other fluorinated polymer thin films for intermetal dielectric (IMD) and interlevel dielectric (ILD) applications in the manufacture of integrated circuits with features <0.25 .mu.m in size.Type: GrantFiled: October 24, 1997Date of Patent: July 11, 2000Assignee: Quester Technology, Inc.Inventors: Chung J.

Decreasing deposition of byproducts increases the amount of thin film, and the quality of the film which can be deposited without requiring the system to be shut down. This increases the throughput of products in the deposition process, thereby increasing the efficiency of electronic device manufacture and lowering the cost.Type: GrantFiled: March 28, 1998Date of Patent: June 27, 2000Assignee: Quester Technology, Inc.Inventors: David Leksell, Ming Xi Chan, Joseph P.

Patent number: 6051321Abstract: Intermetal dielectric (IMD) and interlevel dielectric (ILD) that have dielectric constants (K) ranging from 2.0 to 2.6 are prepared from plasma or photon assisted CVD (PACVD) or transport polymerization (TP). The low K dielectric (LKD) materials are prepared from PACVD or TP of some selected siloxanes and F-containing aromatic compounds. The thin films combine barrier and adhesion layer functions with low dielectric constant functions, thus eliminating the necessity for separate adhesion and barrier layers, and layers of low dielectric constant. The LKD materials disclosed in this invention are particularly useful for <0.18 .mu.m ICs, or when copper is used as conductor in future ICs.Type: GrantFiled: October 24, 1997Date of Patent: April 18, 2000Assignee: Quester Technology, Inc.Inventors: Chung J.

Patent number: 6015759Abstract: Deposition rates of undoped silicate glass dielectric layers on thermal oxide are increased by pre-treating the thermal oxide layer with electromagnetic radiation in the ultraviolet (UV) and/or vacuum ultraviolet (VUV) wavelengths. The surface smoothness of the resulting films are also increased by pre-treating films with UV and/or VUV radiation. Furthermore, the gap filling abilities of the undoped silicate glass films are increased by pre-treating the thermal oxide with UV and/or VUV radiation. New equipment and methods are presented for exposing semiconductor devices to UV and/or VUV radiation, and for enhancing the deposition rates and film quality for semiconductor manufacture. Semiconductor devices incorporating the new methods are also described.Type: GrantFiled: December 8, 1997Date of Patent: January 18, 2000Assignee: Quester Technology, Inc.Inventors: Ashraf R.
