TEM/SEM Aperture Cleaning

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner width="1/2"][vc_column_text css=""] Importance of SEM Aperture Cleaning Pollutions and contaminations are common problems of electron microscopy (EM) vacuum chambers since they are exposed to different samples containing hydrocarbons or polymeric materials. Microscope apertures that are used to align electron beams are important parts of electron microscopy and their contamination may lead to electric charging and beam deflections, resulting in poor-quality imaging. Cleaning electron microscope apertures can be done by thermal evaporation of the impurities or through the plasma cleaning process.

DC Self-Bias in RF Sputtering

Report, Sputtering

[vc_row][vc_column width="3/4"][vc_row_inner css=".vc_custom_1717000964975{margin-right: 10px !important;margin-left: 10px !important;}"][vc_column_inner width="1/2"][vc_column_text css=""] What is DC Self-Bias Voltage? DC self-bias voltage stems from greater electron mobility compared to the ion’s. A higher DC self-bias leads to an elevated rate of ion collision to the electrode, resulting in higher etching or sputtering performance. The sputtering rate from the target in RF sputtering is highly correlated to the DC self-bias voltage created on the target. The DC self-bias is developed by itself and it can be manipulated by effective parameters to form a stable plasma and create better coatings.

The Importance of Vacuum Leakage Detection

Report, Vacuum Coating System, Vacuum Pumps

[vc_row][vc_column width="3/4"][vc_row_inner css=".vc_custom_1717000964975{margin-right: 10px !important;margin-left: 10px !important;}"][vc_column_inner][vc_column_text css=""] Leakage Detection in Vacuum Systems Any vacuum system may suffer leakages that prevents reaching the expected vacuum level to perform the required task. Lowering the gas pressure inside the vacuum chamber causes the atoms and molecules to release in the chamber or penetrate through the leakage sources like holes and cracks into the chamber and hinders evacuating it. (Read more about Effect of Chamber Pressure in Magnetron Sputtering) Vacuum leakage detection methods can help to locate the leaks and seal the leakage sources.

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner width="1/2"][vc_column_text] What is Thermal Evaporation? Thermal evaporation is one of the most popular vacuum deposition method due to its notable merits like simple operation process and proper speed. The thermal evaporation process is one of the physical vapor deposition (PVD) methods in which a thin film of a heated source material is deposited onto the substrate. Different vacuum evaporation methods are named after the various thermal evaporation techniques, such as resistive thermal heating, electron beam evaporation, laser beam evaporation (As pulsed laser deposition method), molecular beam epitaxy (MBE), arc evaporation, and ion plating evaporation.

Ion Beam Sputtering (IBS) Technology

Sputtering, Report

[vc_row][vc_column width="3/4"][vc_column_text] Introduction Ion beam sputtering (IBS) is a physical vapor deposition (PVD) method which provides the highest precision and control among all other thin film deposition methods like thermal evaporation, DC/RF magnetron sputtering and pulsed laser deposition (PLD). The high quality of IBS stems from low chamber pressure and high-energy ions striking the target(s). Offering various advantages from layer uniformity, stability, thickness control, and choice of material (metals, insulators, magnetic materials, refractory metals), ion beam sputtering is of interest to experts of optics, sensors (MEMS), thin film solar cells, and semiconductors.
