Publication number: 20120219727Abstract: The formation of a barrier layer within individual channels or cavities of a microfluidic device is described. The barrier layer is effected through a gas phase deposition process, desirably implemented in a plasma environment using a gas plasma reactor. Judicious selection of a precursor compound used within the gas plasma reactor can provide for generation of a layer on the individual surfaces. Desirably the surface or barrier layer is generated through the chemical adsorption of a metalloid oxide such as a silicon oxide layer on the surface of the individual channels or cavities.Type: ApplicationFiled: June 18, 2010Publication date: August 30, 2012Applicant: Dublin City UniversityInventors: Ram Prasad Gandhiraman, Lourdes Basabe-Desmonts, Asif Riaz, Luke Lee, Ivan Dimov, Jens Ducree, Stephen Michael Daniels

Publication number: 20120177846Abstract: Methods of forming silicon oxide layers are described. The methods include concurrently combining plasma-excited (radical) steam with an unexcited silicon precursor. Nitrogen may be supplied through the plasma-excited route (e.g. by adding ammonia to the steam) and/or by choosing a nitrogen-containing unexcited silicon precursor. The methods result in depositing a silicon-oxygen-and-nitrogen-containing layer on a substrate. The oxygen content of the silicon-oxygen-and-nitrogen-containing layer is then increased to form a silicon oxide layer which may contain little or no nitrogen. The increase in oxygen content may be brought about by annealing the layer in the presence of an oxygen-containing atmosphere and the density of the film may be increased further by raising the temperature even higher in an inert environment.Type: ApplicationFiled: September 19, 2011Publication date: July 12, 2012Applicant: Applied Materials, Inc.Inventors: DongQing Li, Jingmei Liang, Xiaolin Chen, Nitin K.

Patent number: 8216648Abstract: A film formation method includes setting a target object at a temperature of 150 to 550° C., the target object being placed inside the process container configured to hold a vacuum state therein, and then, repeating a cycle alternately including a first supply step and a second supply step a plurality of times to form a silicon nitride film on the target object. The first supply step is a step of supplying monochlorosilane gas as an Si source into the process container while setting the process container at a pressure of 66.65 to 666.5 Pa therein. The second supply step is a step of supplying a nitrogen-containing gas as a nitriding gas into the process container.Type: GrantFiled: November 26, 2010Date of Patent: July 10, 2012Assignee: Tokyo Electron LimitedInventors: Masanobu Matsunaga, Keisuke Suzuki, Jaehyuk Jang, Pao-Hwa Chou, Masato Yonezawa, Masayuki Hasegawa, Kazuhide Hasebe
