Market Dynamics

Global High-K and ALD CVD Metal Precursors Market Drivers

Surging Demand Across Nanotechnology Applications

The high-K precursor market is expected to be driven by microelectronics, nanotechnology, and nanoelectronics technologies. These technologies have the potential for a wide range of applications in next-generation electronic technology, including lighting, display, imaging, and biological imaging technology. High-K materials are increasingly demanded for various potential applications, including high-charge storage, gate dielectrics, electroactive materials, and capacitors. For instance, high-K precursors are imperative for real applications of embedded passives, majorly capacitors.

The embedded passives are emerging technology for microelectronic system integration, which provides size reduction and performance enhancement advantages for many microelectronic systems. Electronic components are in high demand for military and industrial applications, creating opportunities for the high-k and ALD/CVD metal precursors market. These sectors encourage investments in nanotechnology to develop advanced electronic components, which is expected to favor market growth.

Emerging Applications of High-K Materials in LEDs

Thermal management is among the most challenging issues solid-state lighting manufacturers face, such as LED lighting. The increased use of Chip on Board (COB) LED lighting technology in various applications has also propelled high-K dielectric materials due to their thermal resistance capacity. The dielectric substrate material on the PCB has the biggest effect on the thermal resistance of the overall LED package. Growing focus on the lighting market to replace the backlights in the LCDs is expected to drive demand for high-k materials in the LED technology segment. LEDs provide 60,000 hours of life compared to 1,000 hours for incandescent lights and do not involve highly toxic chemicals such as Hg (mercury) in production.

Additionally, advancements in flexible and stretchable electronics (FSE) have been witnessed over the past few years. The FSE technology, a replacement for rigid silicon chip technology, provides disruptive applications such as wearable sensors, electronics on skin/organs, flexible displays, Internet-of-things, and printed RFID tags on the packaging. The FSE technology would also reduce the overall cost of electronic device fabrication. The growing market for FSE technology would also propel the growth of high-K dielectric substrates and precursors in the market.

Global High-K and ALD CVD Metal Precursors Market Restraints

High Risk of Impurity Levels

The determination of hybrid organic-inorganic films, which may be easily developed, will pose a challenge in the high-k metal precursors market over the coming years. The major limitation of high-k instruments is their slow, thin film formation rate. Thick atomic layers are unnecessary as ALD is used to generate substrates used in nanotechnology and microelectronics. Some substrates may not be used due to their impurity or fragility. The saturated processes coupled with self-limiting surface reactions in high-k ALD reactions are estimated to limit the growth of high-k metal precursors.

Ultrapure metal organics are essential for many microelectronic and optoelectronic applications, with the utmost purity of 99.9999% or more. In order to keep impurity levels below parts per billion (ppb), these ultrapure metal-organic sources need special manufacturing routes. All the high-k metal precursors system materials, such as dopants, MO precursors, ammonia, and hydrogen carrier gas, should be supplied with high purity. SSL product developers can implement high-k precursors by integrating or buying modular drivers or working with discrete components to realize custom drivers that allow thin film materials deposition at low temperatures. The design and selection of appropriate metal-organic precursors are critical for the successful development of new ALD processes.
