Description
Technical Field
The invention relates to a cobalt-compatible semi-aqueous cleaning solution for removing a hard mask, a preparation method and application thereof.
Background
In the chip manufacturing technology, the residual cleaning liquid after the plasma etching of the copper interconnection is mainly fluorine-containing cleaning liquid. With the continuous advancement of technology nodes, more and more materials are introduced, such as titanium, tungsten, titanium nitride and other metal materials, low-k dielectric materials and the like, so that the compatibility of the traditional fluorine-containing cleaning solution with various materials is challenging.
Plasma dry etching is commonly used to fabricate vertical sidewall trenches and anisotropic interconnect vias in copper (Cu)/low dielectric constant dual damascene manufacturing processes. As technology nodes evolve to 45nm and smaller (e.g., 28-14 nm), the shrinking dimensions of semiconductor devices makes achieving precise profile control of vias and trenches more challenging. Integrated circuit device companies are researching the use of various hard masks to improve etch selectivity to low dielectric constant materials for better profile control. The hard mask material (e.g., ti/TiN) is removed after the etch protection, and other metals and dielectric materials, particularly cobalt, are protected during the cleaning process to remove the hard mask material, thus challenging the compatibility of conventional fluorine-containing cleaning fluids with a variety of materials.
Developing a cobalt-compatible cleaning solution to selectively remove the hard mask is a problem in the art.
Disclosure of Invention
The invention aims to overcome the defects of poor compatibility and corrosion inhibition performance of the existing cleaning solution for removing the hard mask material on other metals and dielectric materials, poor cleaning effect and the like, and provides a cobalt-compatible semi-water-based cleaning solution for removing a hard mask, a preparation method and application thereof.

Application example 1
(1) Etch rate determination
Etching rate sample to be detected: a dummy wafer (dummy wafer) of a single material such as aluminum, copper, titanium nitride, tungsten, cobalt, dielectric material (low-k or high-k), etc. is deposited on the silicon wafer.
Etching experiment: and (3) statically soaking the sample to be detected in a semi-water-based cleaning solution for 30min at 50 ℃, and then drying by nitrogen after deionized water cleaning.
Method of measuring etch rate (a/min): the thickness of the sample before and after etching was measured separately, wherein the metal sample was measured for thickness using a four-point probe apparatus (CRESTEST-e of Japanese Napson), and the nonmetal sample was measured for thickness using an optical film thickness measuring apparatus (U.S. FILMETRICS F).
Etching effects are classified into four classes: a-compatibility is good, and undercut is avoided; b-very slight undercut; c-having a small undercut; d-undercut is more pronounced and severe.
(2) Cleaning effect measurement
Cleaning effect sample to be detected: patterned wafers with post plasma etch residues and post ash residues with patterned features (metal lines, holes via, metal pad or trench, etc.).
The cleaning effect experimental method comprises the following steps: the sample is statically immersed in a semi-water-based cleaning solution for 20min at 50 ℃, and then is cleaned by deionized water and then dried by nitrogen. The cleaning and corrosion effects were observed with an electron microscope SEM.
The cleaning effect is classified into four grades: a-no residue was observed; b-very little residue was observed; c-small residues were observed; d-significantly more residue was observed.
The etching rates of the semi-aqueous cleaning solutions of examples 1 to 14 and comparative examples 1 to 10 are shown in Table 2, and the etching effects and cleaning effects are shown in Table 3.
TABLE 2
/>
/>
TABLE 3 Table 3
/>
From tables 2 and 3, the semi-water-based cleaning solution of the invention has lower etching rate to AlN xOy、AlN、W、Cu、LP-TEOS、BD2、SiCN、Co、Ti、TiN、TaN、TiNxOy and the like, which shows that the corrosion inhibition performance is better and the cobalt compatibility is good; and after the patterned wafer with the through hole feature and the patterned wafer with the metal line feature are cleaned by the semi-water-based cleaning solution, the undercut phenomenon is hardly observed, which shows that the semi-water-based cleaning solution has good compatibility with various metals and dielectrics. In addition, after the patterned wafer with through hole features and the patterned wafer with metal line features are cleaned by the semi-aqueous cleaning solution of the invention, almost no residues are observed, which indicates that the cleaning effect is good.
Compared with examples 1-14, the semi-aqueous cleaning solutions of comparative examples 1-10 have significantly higher etching rates for AlN xOy, alN, W, cu, LP-TEOS, BD2, siCN, etc., have poor corrosion inhibition performance, or have significantly lower etching rates for Ti, tiN, taN, tiN xOy, etc., and cannot effectively remove the hard mask material, and have significantly higher etching rates for Co, and poor cobalt compatibility. It can be seen that the semi-aqueous cleaning solutions of comparative examples 1-10 do not allow for selective removal of the hard mask material, and have poor compatibility with other metals (especially Co) and dielectric materials. Also, after cleaning the patterned wafer with via features and the patterned wafer with metal line features with the semi-aqueous cleaning solutions of comparative examples 1-10, a more severe undercut phenomenon occurred with more residues.
