Abstract: There is disclosed an attachment (12) suitable for attaching a first component of an article to a second component of the article. The attachment preferably includes a flange portion (20) extending from the first component and one, but preferably, a pair of flange members (22) extending from the second component. The flange portion (12) and the flange members (22) typically interferingly engage one another for attaching the first component to the second component. It has been found that the attachment provided in the present invention is particularly effective for attaching a heat exchanger (14) to another component such as a shroud or another heat exchanger (16) together for forming a heat exchanger assembly (10).

Abstract: A method of formation of a damascene FSG film with good adhesion to silicon nitride in an HDP-CVD system. Silane (SiH4), silicon tetrafluoride (SiF4), oxygen (O2) and argon (Ar) are used as the reactant gases. SiH4, SiF4, and O2 react to form the FSG. Ar is introduced to promote gas dissociation. All four gases are used for depositing most of the FSG film. SiH4 is not used during deposition of the interfacial part of the FSG film. The interfacial part of the FSG film refers either to the topmost portion, if silicon nitride is to be deposited on top of the FSG or the bottom portion if the FSG is to be deposited on top of silicon nitride. Using SiH4 with the SiF4 tends to mitigate the destructive effects of SiF4 throughout most of the deposition. By removing the SiH4 from the deposition of the interfacial part of the FSG film less hydrogen is incorporated into the film in the interfacial region and adhesion to overlying or underlying silicon nitride is improved.

Abstract: A method and apparatus for modifying the profile of narrow, high-aspect-ratio gaps on a semiconductor substrate are used to fill the gaps in a void-free manner. Differential heating characteristics of a substrate in a high-density plasma chemical vapor deposition (HDP-CVD) system helps to prevent the gaps from being pinched off before they are filled. The power distribution between coils forming the plasma varies the angular dependence of the sputter etch component of the plasma, and thus may be used to modify the gap profile, independently or in conjunction with differential heating. A heat source may be applied to the backside of a substrate during the concurrent deposition/etch process to further enhance the profile modification characteristics of differential heating.
