Why Did My Bond Melt?

April 21, 2020 | By KJLC Blog

As a Product Manager in the Materials Division, I field a lot of questions from customers from many different industries with varying degrees of sputtering experience. One of the more common emails that I receive goes something along the lines of, "There's something wrong with my bonding because the indium has melted out of the sides of my target." Often times the user has waited for their target, spent money on it, only to use it one time and had to stop due to the melted bond. A frustrating situation for sure.

The Effect of Sputter Cathode Design on Deposition Parameters: Design Enhancements Expand Capabilities for the Magnetron Sputtering of Thin Films

July 22, 2019 | By KJLC Innovate

Sputtering is a relatively mature approach for the deposition of a variety of thin film materials. Initial publications on the process date to the early 1800s. In its simplest form sputtering provides a route to manufacture high quality reflective coatings for mirrors and potato chip bags; and at the extreme end, for creating the most advanced semiconductor computing devices in the world.

Sources and Solutions for Contamination Issues in Space Simulation (TVAC) Systems

May 09, 2018 | By KJLC Innovate

The current push to commercialize space travel has resulted in renewed demand to launch objects and even people into earth orbit or event deep space. Companies including SpaceX, Blue Origin and Rocket Lab have demonstrated the ability to make certain portions of a launch vehicle reusable and that may dramatically alter the cost to get to space. True rocket ship factories are emerging which, in one case, can put out a couple of full blown launch vehicles every month!

KJLC® Awarded a Patent for its Atomic Layer Deposition System and Process

November 28, 2017 | By KJLC Innovate

The Kurt J. Lesker Company® (KJLC®), a global manufacturer of vacuum systems, thin film deposition tools and vacuum components, today announced that the United States Patent and Trademark Office has issued US patent number 9,695,510, 'Atomic Layer Deposition Apparatus and Process', covering the design of an atomic layer deposition system and the process to use that system to deposit highly precise and conformal thin films. This proprietary technology substantially reduces the interaction of various precursor gas molecules with the internal surfaces of the reaction chamber and enables actual focusing of gas streams to more effectively coat the surface of arbitrarily large substrates.

KJLC Featured at the 70th Annual Gaseous Electronics Conference

November 28, 2017 | By KJLC Blog

On 6 November 2017 our Jason Hrebik and J.R. Gaines delivered presentations at the 70th annual conference on Gaseous Electronics (GEC2017), held at the Doubletree Hotel, Green Tree, PA. Hrebik displayed his expertise through a presentation on the capabilities and benefits of the High Power Impulse Sputtering (HiPIMs) process and provided the audience with an introduction to the new KJLC Impulse™ power supply. The conference featured a group of presentations from industrial companies, including LAM Research, Applied Materials, and Tokyo Electron. Gaines capped off the afternoon session with a review of the practical issues associated with the integration and application of plasmas in Plasma-Enhanced Atomic Layer Deposition (PEALD).

Fresh Insights on the Flow of Electrons by Direct Observation of Spoke Evolution in Magnetron Sputtering

October 25, 2017 | By KJLC Innovate

In a July 2017 publication, Drs. André Anders and Yuchen Yang provide an enhanced description of the flows and energy of electrons at the face of a magnetron sputter cathode. By combining a unique imaging process and a linear cathode (target) the researchers were able to generate a series of time/space images which shows plasma instabilities driven by the motion of electrons, within the cathode's magnetic field. The images show the effects on plasma flow for both conventional DC magnetron sputtering (dcMS) and also high power impulse magnetron sputtering (HiPIMs). The full paper is available on line at http://aip.scitation.org/doi/10.1063/1.4994192.

Novel Deposition System Designs for Thin Film Materials Research

February 20, 2017 | By KJLC Innovate

Next generation vacuum deposition systems must evolve in order to keep pace with the ongoing evolution of thin film materials and devices. Researchers seeking to pursue new areas, such as biomedical devices, 2D materials, specialized magnetics and oxide-based films need new tools to support their work. The frontiers of materials science, particularly at the intersection of biology and thin film deposition, have brought new materials into the vacuum space that were never intended to be there.

Challenges for Non-Ideal Atomic Layer Deposition Processes & Systems

May 09, 2016 | By KJLC Innovate

ALD has been described as a thin film deposition technology that can keep the semiconductor industry on track per Moore's law (or observation) [1] for a few more years. In its most ideal form, it is a process that enables monolayer, or sub-monolayer growth of certain materials through the sequential exposure of a functionalized substrate to a pair of precursor gases. If dosed correctly the gases attach at specific surface sites and react to create a near perfect film on the order of a few angstroms thick. Presently the U.S. Department of Defense anticipates that the last process node for semiconductor devices (the end of Moore's) is 7 nm and will be achieved by 2020 [2].

Combinatorial Magnetron Sputtering Advances with New Tools and New Predictive Techniques

January 19, 2016 | By KJLC Innovate

Combinatorial Magnetron Sputtering (CMS) has distinguished itself as a viable tool for the rapid development of vast libraries of complex materials. Researchers at the Joint Center for Artificial Photosynthesis, California Institute of Technology (Cal Tech) and the Kurt J. Lesker Company® (KJLC®) [1] have recently published work on Combinatorial Magnetron Sputtering (CMS) using a novel robotically controlled thin film deposition cathode tilt and substrate manipulation mechanism. Combinations of metal alloys, mixed metal oxides and nitrides have been demonstrated with the system as a basis for a predictive model developed by Cal Tech to streamline the design of new materials for certain critical applications.
