What will be your role?

Directing matter to create structures with atomic-level control of physical and chemical properties is a long sought-after goal in nanotechnology. The deposition of atoms at specific locations on a pre-patterned surface can boost advances in catalysis, energy harvesting, and semiconductor device fabrication. To fabricate advanced multilayered 3D devices with perfectly aligned features the current conventional manufacturing approach requires many lithography and etching steps (i.e. top-down). Innovative bottom-up techniques are required to replace or complement top-down fabrication schemes. One of the main emerging solutions is to implement self-aligned fabrication schemes, in which a material is deposited on a pre-determined area in a selective manner. Area-selective deposition can enable cost-effective options to create the above mentioned structures in a bottom-up approach.The focus of this research project is to investigate area-selective deposition of thin-films in a spatial-atomic layer deposition (ALD) mode for semiconductor device fabrication. ALD is a layer-by-layer deposition method that allows for atomic-level control over thickness and material properties, resulting in conformal and uniform deposition over large area and high aspect ratio substrates. Such unique features stem from the fact that, in the most simple case, ALD relies on cyclic and self-limiting chemical reactions between the substrate surface and alternating exposure to a precursor and co-reactant.TNO-Holst Centre has developed this technique as a high-rate deposition version of conventional time-sequenced ALD.4 The research objective is to find viable small molecule inhibitors that can be implemented for achieving high-selectivity as well as develop in-line etching correction processes to lower the defectivity. Central for this project is a good affinity for thin-film surface chemistry encompassing both cutting-edge deposition, pre-treatments and etching processes. The goal is to develop novel area-selective spatial ALD processes, etching correction steps and understand the underlying fundamentals.

The project will be carried out in collaboration with leading semiconductor manufacturer and equipment companies, where the aim is to develop novel area-selective spatial ALD processes. Depending on the pre-treatment, using small molecule inhibitors and the deposition chemistry, thin-film nucleation can be delayed only on specific target surfaces. This can be exploited to achieve area-selective ALD. In this project, you will use Fourier transform infrared spectroscopy (FTIR) to study the interaction of pre-selected chemicals with substrates that contain several pre-patterned surface coatings. This will serve as a starting point for studying and understanding the effect of such chemicals on the nucleation and growth behavior of nitrides and oxides on different starting substrates. You will help in designing ALD processes study the thickness evolution and monitor the process during deposition as well as etching of materials on different surfaces, using ex-situ spectroscopic ellipsometry (SE). Advanced characterization techniques such as transmission electron microscopy (TEM) and low energy ion spectroscopy (LEIS) can be conducted at our project partners site.
