Patent number: 6541400Abstract: An improved process for depositing a robust fluorosilicate glass film on a substrate in a chamber includes maintaining a total pressure in the chamber of less than about 1.7 torr, introducing vapor phase chemicals such as N2, SiF4, SiH4, and N2O into the chamber, and reacting the vapor-phase chemicals with sufficiently supplied energy to deposit a thin film layer of the fluorosilicate glass on the substrate. Advantageously, the deposited fluorosilicate glass films are chemically, mechanically, and thermally stable without additional processing. Also advantageously, the films are deposited uniformly at rates greater than about 5000 Angstroms per minute with dielectric constants of about 3.4 to about 3.9.Type: GrantFiled: February 9, 2000Date of Patent: April 1, 2003Assignee: Novellus Systems, Inc.Inventors: Jason L. Tian, Harald Te Nijenhuis

Patent number: 6537707Abstract: A method of fabricating a high energy radiation mask, such as a laser ablation mask for manufacturing inkjet printheads, includes a multi-stage evacuation process and/or a step of reducing the deposition rate of silicon dioxide during formation of a dielectric stack. When the multi-stage evacuation procedure is combined with the slower deposition rate of silicon dioxide, the resulting mask has a surprisingly low defect density. In the first embodiment, the evacuation procedure is initiated using a low-rate first evacuation connection. The relatively slow purging of a vacuum chamber in which the dielectric stack is subsequently formed controls turbulence and environmental changes that can generate contamination and water along the surface of the substrate on which the dielectric stack is formed. When a pressure setpoint is reached, a second roughing connection is activated to increase the speed of the procedure. The second connection has a higher maximum rate than the first connection.Type: GrantFiled: March 15, 2000Date of Patent: March 25, 2003Assignee: Agilent Technologies, Inc.Inventor: Lawrence Hakchu Lee

Patent number: 6537622Abstract: This method of prevention of particle pollution in a pre-clean chamber includes an oxygen gas supplying step for injecting oxygen gas into the pre-clean chamber; and a plasma generating step for ionizing the oxygen gas into plasma so as to interact with silicon-rich oxide to form a silicon oxide layer in the pre-clean chamber. The method according to the invention could prevent particle pollution due to peeling-off of silicon-rich oxide in a pre-clean chamber so as to prolong the life of a bell-jar therein.Type: GrantFiled: May 4, 2001Date of Patent: March 25, 2003Assignee: Silicon Integrated Systems Corp.Inventors: Chia-ming Kuo, Chao-yuan Huang

Patent number: 6531412Abstract: A method is described for forming a low-k dielectric film, in particular, a pre-metal dielectric (PMD) on a semiconductor wafer which has good gap-filling characteristics. The method uses a thermal sub-atmospheric CVD process that includes a carbon-containing organometallic precusor such as TMCTS or OMCTS, an ozone-containing gas, and a source of dopants for gettering alkali elements and for lowering the reflow temperature of the dielectric while attaining the desired low-k and gap-filling properties of the dielectric film. Phosphorous is a preferred dopant for gettering alkali elements such as sodium. Additional dopants for lowering the reflow temperature include, but are not limited to boron, germanium, arsenic, fluorine or combinations thereof.Type: GrantFiled: August 10, 2001Date of Patent: March 11, 2003Assignees: International Business Machines Corporation, Infineon Technologies AGInventors: Richard A.
