Assignee:

Applied Materials, Inc. - Santa Clara CA

International Classification:

C23C 1600

US Classification:

118696, 118728, 118500

Abstract:

A method for aligning a wafer on a support member within a vacuum chamber includes increasing the pressure within the vacuum chamber to at least about 1 Torr before aligning the wafer. The wafer is introduced into the vacuum chamber on the support member, the pressure is increased to at least about one Torr, and the support member is lifted into a shadow ring that has a frustoconical inner cavity constructed to funnel the wafer to a centered, aligned position.

Abstract:

A method and apparatus for directing a process gas through a processing apparatus, such as a vapor deposition chamber. The apparatus comprises a pumping plate for a processing chamber having an annular body member wherein said body member has a first portion and a second defining a circumferential edge and a central opening. The first portion comprises a sidewall of the circumferential edge having a plurality of circumferentially spaced through holes and the second portion has comprises a lateral portion that protrudes from the circumferential edge, such that, in a processing chamber, the first portion defines a first gas flow region comprising the central opening and a second gas flow region comprising the lateral portion of the second portion.

Abstract:

A method of depositing a low dielectric constant film on a substrate. In one embodiment, the method includes the steps of positioning the substrate in a deposition chamber, providing a gas mixture to the deposition chamber, in which the gas mixture is comprised of one or more cyclic organosilicon compounds, one or more aliphatic compounds and one or more oxidizing gases. The method further includes reacting the gas mixture in the presence of an electric field to form the low dielectric constant film on the semiconductor substrate. The electric field is generated using a very high frequency power having a frequency in a range of about 20 MHz to about 100 MHz.

Abstract:

A brush mounting system for a wafer scrubbing device includes a brush mandrel and a mounting assembly on which the brush mandrel is mounted. The mounting assembly includes a mounting member adapted to be mounted to a wall of the wafer scrubbing device, and a bearing secured to the mounting member. A brush support is rotatably mounted on the bearing and has an outer end that includes a contact surface adapted to contact the brush mandrel. The contact surface has a spherical profile. The brush mandrel includes a corresponding contact surface having a spherical profile, so that the brush mandrel and the mounting assembly form a spherical joint at the point of contact.
