Global High-k and ALD/CVD Metal Precursors Market: Snapshot
The drive for demand for chemical vapor deposition (CVD) techniques stems from the declining performance and lack of reliability of conventional SiO2 gate dielectrics. CVD and its usually considered subset atomic layer deposition (ALD) are thin film deposition techniques used in semiconductor device manufacturing. These processes are used to deposit multi-component thin films by the co-injecting Hf and Si precursors, leading to the formation of homogeneous single-layer films, endowing excellent electric properties of dielectric materials.

These thin films have wide number of industrial applications for making novel electronic components. Over the past few years, high-k and ALD/CVD metal precursors have gained increased prominence in making memory devices and high-dielectric metal gates used in advanced logic devices. In recent years, the use of CVD/ALD is proving promising in the defense and civil sectors where thin films are being adopted in multiple cross-platform applications. The ALD/CVD method is increasingly being used to make components used in non-volatile memories, capacitors dielectrics, organic thin film transistors, and dynamic random-access memory (DRAM).
The constant demand for miniaturization and the need for improving performance of a variety of electronics and semiconductor devices are key factors boosting the evolution of the high-k and ALD/CVD metal precursors market. The ALD/CVD process is viable for metals such as palladium, platinum, and rhodium. The use of metals such as germanium and tantalum are being researched for their viability for the process.
The low thermal stability of metal-organic (MO) compounds is expected to influence the growth of the high-k and ALD/CVD metal precursors market in the coming years. In addition, the soaring demand for a more advanced IC device structures in the area of semiconductor device manufacturing is likely to unlock exciting opportunities for vendors in the high-k and ALD/CVD metal precursors market.

Global High-k and ALD/CVD Metal Precursors Market: Overview
High-k is a material having a high dielectric constant, with the threshold for comparison being the dielectric constant of silicon dioxide, which has been for decades the de-facto material for the gate dielectric layer of a device. High-k dielectrics commonly find usage in the process of semiconductor manufacturing, a strategy known to come into use to allow further reduction in size of microelectronic components.
Atomic layer deposition (ALD) and chemical vapor deposition (CVD) are thin film deposition techniques, with ALD often considered a sub-set of CVD and both techniques depending on some sort of chemical reaction between the substrate and the material to be deposited. These processes are often used for producing thin films in the semiconductor industry. Over the past few years, the usage of high-k films deposited through thin film deposition methods such ALD and CVD have significantly increased, especially in the production of memory devices and high-k metal gates in logic devices.
Global High-k and ALD/CVD Metal Precursors Market: Key Trends
The global market for high-k and ALD/CVD metal precursors is driven chiefly due to the rising demand for increasingly miniaturized and improved semiconductor devices across the globe. The lack of deposition uniformity achieved during the deposition of phase-change materials with the help of conventional techniques such as physical vapor deposition is also a key factor to have driven interest of the semiconductors community into ALD/CVD deposition techniques.
Besides, thin film deposition techniques have enabled significant developments in areas such as electronic semiconductor devices, optical coatings, magnetic recording media, and LEDs. The thriving global market for all or most of these areas of application is also one of the prime factors expected to lead to an increased demand for high-k dielectrics and ALD/CVD metal precursors in the next few years.
In terms of precursor technology, the global high-k and ALD/CVD metal precursor market witnesses the dominant share in demand for the segment of interconnects. High-k precursors also find extensive usage for manufacturing of metal gates for use in logic devices. In the next few years, the market is expected to see sizeable rise in demand across these areas owing to the rising demand for miniaturized semiconductors and small-sized electronic devices. The segment of capacitors and memory devices will see an increased set of opportunities for players in the high-k and ALD/CVD metal precursor market.
Global High-k and ALD/CVD Metal Precursors Market: Regional Outlook
From a geographic standpoint, the global high-k and ALD/CVD metal precursors market is led by Asia Pacific, which is presently in the lead with a sizeable margin. The region is also expected to remain the leading consumer of high-k dielectrics and ALD/CVD metal precursors over the report’s forecast period as well, chiefly owing to the promising electronics industry in countries such as Japan and China. The continuous rise in demand for miniaturized semiconductor devices in the region is also expected to drive the demand for high-k and ALD/CVD metal precursors.
North America follows Asia Pacific in terms of revenue valuation as well as consumption of high-k and ALD/CVD metal precursors. The region is expected to exhibit growth at a steady pace in the next few years owing to the high demand for technologically advanced electronic devices.
Global High-k and ALD/CVD Metal Precursors Market: Competitive Analysis
One of the key challenges faced by companies operating in the intensely competitive high-k and ALD/CVD metal precursors market is the fact that the process of atomic layer deposition is only limited to few noble metals such as platinum, palladium, and rhodium. The usage of these rare and costly metals makes the process of thin film deposition cost-intensive and one with a potentially low profit margin. Some of the key vendors presently operating in the market are Dynamic Network Factory Inc, Dow Chemical, NANMAT, JSR Corporation, Samsung Electronics, and Adeka Corporation.
