Chemistry formulation and process development was performed at ATMI and IBM Research.
Combinatorial chemistry experiments aimed at high-throughput screening of chemistries / process conditions were carried out at ATMI and Intermolecular, using an Intermolecular TempusTM F20 High-Productivity Combinatorial Tool.
The two wet process steps consisted of wafer immersion (static beakers) in chemistry A (Chem A) at 70°C, and then in chemistry B (Chem B) at 50°C, respectively.
Figure 3 shows cross-section electron micrographs of representative patterned Si test structures, for which the stack is: poly-Si (~100nm) / TiN (≤10nm) / bulk Si.
The test structures are completely exposed to all chemistries during wet processing (i.e. no sidewall spacers are present).

Therefore, it was decided to develop a computer application that would be helpful to any researcher in the field of chemistry and materials science.
The developed computer programme “Characteristics of chemical bond and their influence on structure and properties of simple substances and oxides” [10] allows researchers in the field of general chemistry and materials science to obtain complete and reliable information on the effect of chemical bond characteristics on structure and properties of homo- and heteronuclear compounds.

Figure 3 shows a cross-section SEM image of the sample structure.
The latter consisted of a Cu-compatible formulated chemistry typically used for post-etch residue removal.
Clearly, by applying Nanolift process, residues on the structure were completely removed.
Negligible k-value shift was confirmed after formulated chemistry and Nanolift process compared to the sample without process.
Also, negligible k-value shift was confirmed by k-value measurement and it was comparable with conventional wet cleaning using formulated Cu post etch residue removal chemistry.

Chemistry Representative backscattered electron (BSE) SEM images showing the microstructures of the powder particles are presented in Fig. 4 a)b)c)d) Figure 4 Cross-sectional BSE SEM images of powder particles (a) A1(45-100μm), (b) A2(106-180μm), (c) B1(45-100μm), (d) B2(180-200 μm) In the structure of particles A2, B1, B2 there are no pores and other inclusions.
The powder chemistries, including alloying and impurity content, are specified with different standards and as a main requirement powders have to comply with these standard chemistries.
In samples obtained from powder A2 (106-180 µm) and B2 (180-200 µm), the structure is coarse-grained.
The presence of satellite on the powder surface has no effect on the formation of defects and structure.
