Retech has teamed up with GeniCore to represent their Spark Plasma Sintering (SPS) technology in the North American market. Spark Plasma Sintering (SPS) technology, also called Field Assisted Sintering Technology (FAST), enables effective consolidation of pure metal powders, metal alloys, as well as ceramic and metal composites using pulsed direct current. The SPS process bonds materials using a combination of pressure and thermal energy applied to materials in a mold. It resembles Hot Pressing, but the SPS process consumes far less energy and, most importantly, can bond a broader range of materials into novel composites unachievable by other processes. The “spark” in spark plasma sintering is more of a powerful pulse of electric current that passes directly through the material in the mold form while it is under pressure. To withstand the heat and pressure, the molds are made of graphite, which is machined into a negative shape. As the material is compressed in the mold while under vacuum, a pulse of direct current is passed through the material, producing the high temperatures necessary for sinter bonding to occur. The current pulse heats the material via Joule heating rather than radiant, applying the heat only where needed, thereby using less energy than traditional hot pressing or sintering methods. GeniCore’s pioneering advancement in SPS/FAST technology is in their Direct Current (DC) electric pulse switching, enabling the most precise DC waveform control in the emerging SPS industry — controlling each pulse’s current, duration, and spacing -- hence the name Upgraded Field Assisted Sintering Technology (U-FAST). Generating pulses of under one millisecond, and even, precisely programmable square-pulse packets, delivers tremendous energy directly into the materials being consolidated. This precision pulse control, in turn, breeds the greatest precision in sintering, resulting in uniform consolidation with minimal grain growth. Process trials yield material compositions unachievable by any other processes. GeniCore U-FAST devices are available in the four different configurations listed below to accommodate varying applications, part sizes, production throughput, and budgets. Additionally, the modular design allows for any of the configurations to be upgraded to the next larger model.

An SPS machine is a type of machine that is used to create or process semiconductor wafers. These machines are typically used in the manufacturing process of various semiconductor devices. The SPS type of machine works by depositing a thin film of material onto a wafer. This film is then processed to create the desired semiconductor device. The process of creating the film is known as sputtering.
The Argon Atoms Collide with the Target Material
Sputtering is a type of physical vapor deposition (PVD) technique. In PVD, a target material is placed in a chamber and heated until it becomes a vapor. The chamber is then filled with an inert gas, such as argon. As the argon atoms collide with the target material, they knock off atoms of the target material. These atoms are then deposited onto the wafer, forming a thin film.
Semiconductor Manufacturing
Sputtering is a relatively low-cost and efficient way to create semiconductor devices. It is also a relatively clean process, making it ideal for use in semiconductor manufacturing.
