Ozone chemistry for BEOL resist stripping - A systematic analytical attempt to understand the interaction of O3 with modern DUV-resists Mathias Guder1a, Maren Pellowska, Maximilian Pohland, Michael Dalmer2c Bernd Kolbesen1b 1 Goethe University Frankfurt/Main, Institute of Inorganic and Analytical Chemistry, Max-von-Laue-Str. 7, D-60438 Frankfurt, Germany 2 SEZ AG, SEZ-Straße 1, A-9500 Villach, Austria a m.guder@chemie.uni-frankfurt.de, bkolbesen@chemie.uni-frankfurt.de, cM.Dalmer@at.sez.com Keywords: ozone, radicals, decomposition, radical trapping, resist characterization Introduction This work deals with the application of ozonated water for the BEOL stripping of DUV-resists.
The aim is to be able to determine the concentrations of O3, its decomposition, under the influence of various parameters, and to correlate these data with the polymer structure of the resist on the wafer and the efficiency of resist removal.
Knowledge of the resist composition enables the assignment of peaks to functional groups of the components of the resist and allows the determination of chemical structures and the changes they undergo.

Clearly, many of these factors reside within the interfaces linking the product ferrite to the parent phase; these factors may include interface chemistry (including segregation and co-segregation tendencies) interface structure, energy and related anisotropies, and interface mobility and associated anisotropies.

Ferrite growth under conditions of controlled decarburization: Studies of ferrite growth under conditions of controlled decarburization offer the possibility to deconvolute the different effects of interface structure and chemistry [37].
Growth of Widmanstätten ferrite and bainite: In attempting to sort out the various factors governing ferrite growth, it is helpful to separate those related to the structure and mobility of the interface from those that are chemistry-dependent (to the extent that this is possible).
It is also clear that further simultaneous observations of interface structure and chemistry will be of value in defining a correlation among structure, segregation potential and kinetic response.

Internet of things is defined as a huge network combing with the Internet through using all kinds of information sensing equipments to collect all kinds of required information such as sound, light, heat, electricity, mechanics, chemistry, biology, and position.
Such a simple network structure has the ability to simplify the composition of equipments superficially, but actually makes the space for the play of equipment's role weakened.
Therefore, analyzed from the structure of networking and the superior controllable performances of Internet of things, Internet of things will be crucial in future computer application system.
