Increasing Throughput in Sputtering and Evaporation

Posted on

As integral as throughput is when it comes to meeting production needs, there is no single answer for improving throughput, especially across different deposition methods. With both evaporation and magnetron sputtering, there are a number of factors you need to consider in order to raise your total throughput. Improving Throughput in Magnetron Sputtering With a… Read More

When comparing the four main types of physical vapor deposition (PVD) for thin films, it is important to know the benefits and drawbacks of each before you decide which method will best suit your application. PVD can occur through sputtering (magnetron or ion beam), which utilizes energetic ions colliding with a target to eject (or… Read More

Closure Rate and Uniformity in Indium Bump Deposition

Posted on

In indium bump deposition, there is a tradeoff between closure rate and closure uniformity. A slower closure rate and high closure uniformity is ideal, but often, the closer you get to your desired specs in one area, the more you sacrifice with the other. Closure Rate vs. Closure Uniformity Closure rate: This refers to the… Read More

Grain size refers to the size of the individual crystallites or particles that compose a solid metal. Grain size, as well as the boundaries between the grains, are important factors for determining physical properties of the entire metal. In thin film deposition, if the particles are deposited with high energy, and there is a high… Read More

Considerations for Indium Bump Deposition

With today’s technological advances, higher pixel density in focal plane arrays is a necessity as demand for improved visual quality goes up. Because of this, feature sizes on focal plane arrays are getting smaller, which requires higher density interconnects to bond the detector array to the readout chip. The current electroplating process just can’t deliver… Read More

Ion beam deposition (IBD) is a thin film deposition method that produces the highest quality films with excellent precision. Also referred to as ion beam sputtering (IBS), it’s a process that’s used when tight control over film thickness and stoichiometry is needed. How it Works During the ion beam deposition process, an ion source is… Read More
