Program currently open to ALL regions around the world
Park Systems, the world’s leading manufacturer of atomic force microscopes (AFM) invites all researchers worldwide to apply to become Park AFM Scholars and receive a research scholarship. Park AFM Scholarship Awards are open to undergraduate or postdoctoral students working in nanotechnology research either already using Park AFM or who have research they would like to do with a Park AFM and need help getting access to equipment. Through this program, Park Systems has offered assistance to many researchers who qualify as Park AFM Scholars by matching them with one of thousands of nanoscience shared user facilities to perform their research using Park AFMs.
“We not only offer financial incentive to Park AFM Scholars who are pioneering new research methodologies in nanotechnology at leading academic institutions worldwide, but most importantly are giving them access to our Park atomic force microscopes,” stated Keibock Lee, Park Systems President. “We will continue to advance nanoscale discoveries thru this Park AFM Scholarship program worldwide.”
The Park AFM Scholarship Award is open to postdoctoral researchers and graduate students working in nanotechnology research using Park AFM. As progress for nanotechnology research and development advances at an unprecedented rate, universities worldwide offer degrees in fields working with nanotechnology. Park Systems, world-leading manufacturer of atomic force microscopes, is offering a $500 USD monetary scholarship to promote the education of future scientists and engineers in a number of nanoscience research areas that require advanced nanoscale microscopy for sample analysis and observation and to promote shared research findings and methodologies amongst their peers.
Park AFM Scholarship Program Accepting Submissions

Title of Research Paper: Post-CMP Cleaning of Ceria Particles from Silicon Dioxide and Nitride Wafers for Advanced Technology Nodes
Advanced device manufacturing requires stringent process conditions to prevent defects that can lead to device failure and reliability issues. In particular, defects such as residual particles, foreign materials, scratches, etc. should be removed from the wafer surface after chemical mechanical planarization (CMP).
How do you use AFM in your research?
Chemical mechanical planarization (CMP) is one of the most crucial steps in the manufacturing of integrated circuits (ICs). In a typical CMP process, a wafer is pressed against the polishing pad fixed to a rotating platen and the chemical slurry (consisting of abrasive particles and necessary chemical additives) is supplied on to the pad. The wafer is polished by the combination of chemical and mechanical forces. CMP inevitably introduces surface defects and contaminants due to the presence of chemical additives and abrasive particles in the slurry used to planarize wafer surfaces. Surface particles are one of the major defects induced by CMP. If not removed, they can cause short or open circuits and affect the final device performance and reliability. Therefore, cleaning such particlulate defects on wafer surfaces post-CMP is critical for successful manufacturing of ICs to improve productivity. Billion or so active transistors in each IC is electrically isolated using shallow trench isolation (STI) CMP. Ceria particle-based slurries are used to polish STI structures. Due to high chemical affinity of ceria particles to silicon dioxide surfaces, STI CMP leads to particle contamination making post-CMP cleaning challenging as ceria particles adhere very strongly to STI wafers during polishing. In our research, we are developing cleaning chemistries than can remove ceria particles from silicon dioxide wafers. The particles on silicon dioxide wafer surfaces before and after cleaning are imaged using atomic force microscopy (AFM) and counted. Subsequently, cleaning efficiency is calculated to evaluate the effectiveness of the developed cleaning chemistry.
“Particles on wafer surfaces can be imaged easily using AFM as compared to other microscopic techniques. Some of the benefits of using AFM over other microscopic techniques are as follows: even very small nanoparticles (<20nm) can be imaged easily using AFM; imaging wafers using AFM does not require any sample preparation; AFM is a simple, flexible, and cost effective technique and the image quality is excellent with good reproducabilty; AFM images can be further processed to obtain more information like size, surface quality, etc.” Akshay Gowda
