High-Density Magnesium Oxide Sputtering Targets (MgO) for Spintronics
Achieve next-level performance and stability in spintronics with our premium High-Density Magnesium Oxide (MgO) sputtering targets. As the gold standard for creating crystalline tunnel barriers, MgO thin films are the core component of Magnetic Tunnel Junctions (MTJs) and high-speed, non-volatile MRAM (Magnetic RAM). To ensure success, we supply targets with ultra-high 99.99% purity and a superior density of 3.58 g/cm³. This high density is critical because MgO is naturally hygroscopic; a dense target resists moisture absorption, prevents cracking, and ensures the stable, high-crystallinity deposition required for advanced semiconductor and high-frequency electronics.

Critical Applications: Spintronics, Displays, and Superconductors
Our high-density MgO deposition source materials are engineered for the most demanding thin-film applications:
Magnetic Tunnel Junctions (MTJ)
First, MgO is the definitive magnetic tunnel junction barrier material. Specifically, it enables the high Tunneling Magnetoresistance (TMR) ratios required for modern read heads and MRAM devices.

Plasma Display Panels (PDP)
In addition, MgO serves as a vital MgO protective layer in plasma displays. It functions by protecting the dielectric layer from ion bombardment while simultaneously providing a high secondary electron emission coefficient, which lowers the firing voltage.

Superconductor Buffer Layers
Finally, MgO is widely used as a MgO buffer layer for High-Temperature Superconductors (HTS) like YBCO. Because of its excellent lattice matching and chemical inertness, it facilitates the epitaxial growth of superconducting films on various substrates.

Manufacturing Excellence for High-Density Ceramics
We manufacture dielectric magnesium oxide targets with a focus on structural integrity and purity.
-
High-Density Sintering: Our targets are processed to achieve theoretical densities nearing 100%. This is crucial for MgO, as low-density targets can trap moisture and gas, leading to arcing and particulates during the sputtering process.
-
Custom Bonding: Due to the brittle nature of ceramic oxides, we offer specialized Elastomer and Indium Bonding services. This ensures adequate thermal transfer and stress relief between the target and the backing plate, preventing cracking during high-power deposition.
Indium Bonding Services
ITO is a ceramic material that requires precise thermal management to prevent cracking. Our in-house Indium Bonding service ensures optimal thermal and electrical conductivity between the target and backing plate, extending target life and stabilizing your deposition rates.
Indium Recycling and Reclaim
Indium is a valuable resource. Don’t let your spent targets go to waste. We offer a comprehensive reclamation program to recover Indium from your used targets and backing plates, significantly lowering your total cost of ownership.
