From advanced data centers powered by AI to smarter cars and machines, modern technology relies on highly developed semiconductors. However, the development of such chips involves much more than just novel designs and cutting-edge technology.
Materials used during manufacturing are another important aspect of performance, consistency, and yields. The more manufacturers increase their production and develop smaller, more complicated products, the more need arises for manufacturing materials of high quality.
This trend creates new opportunities for manufacturers of materials but imposes additional challenges at the same time. Understanding the current trends and challenges allows us to realize why advanced materials are so crucial to the next stage of the development of the semiconductor industry.
Artificial intelligence is a major source of demand. Data centers need processors, memory, and networking chips capable of handling increasingly intensive workloads. The Semiconductor Industry Association reported in October 2026 that worldwide chip sales had surpassed $1 trillion in the first eight months of the year.
Other industries add different requirements. Electric vehicles and connected cars rely on power management, sensing, and control electronics. Industrial automation uses chips in robotics, machine-vision systems, and connected factory equipment. Consumer devices continue to demand efficient processors and increasingly sophisticated connectivity.
Fabricators are also making investments in new fabrication capacities and improvements to old fabrication facilities. These projects create equipment demand, followed by materials consumption during process qualification and production ramp-up. Ongoing demand for wafers, chemicals, gases, and deposition materials depends on actual production activity and the processes being used.
Demand varies by application and process. Automotive, advanced logic, and memory devices can require different material compositions, impurity limits, and reliability qualifications. Suppliers should be able to meet the requirements of processes used by their customers.
Most normal integrated circuits usually start from well-prepared silicon wafers. Their crystal quality, surface condition, and dimensional consistency help determine how predictably later manufacturing steps perform. Defects or contamination introduced early can affect many subsequent operations, making incoming material controls particularly important.
Wafers are only one part of the picture. Photoresists, specialty gases, wet chemicals, dielectric materials, and high-purity metals support patterning, cleaning, insulation, and electrical connections.
Specifications differ by application, but the common requirement is repeatability. Manufacturers need confidence that successive lots behave consistently inside a qualified production process.
Sputtering is a form of physical vapor deposition (PVD). Energetic ions strike a solid sputtering target, releasing atoms that deposit as a thin film onto a wafer or another substrate.
According to the design of the circuit board, these materials can be used to make conductive, adhesive, or barrier layers. PVD is one of several deposition methods used in semiconductor production.
For sputtering targets, chemical purity matters alongside density, grain structure, dimensions, and compatibility with the deposition equipment. Variations can affect particle generation, film uniformity, or process stability. This makes supplier qualification a technical exercise as well as a commercial one.
Engineering and procurement teams therefore need agreed acceptance criteria before comparing specialized suppliers such as Vem Co. Target composition, contamination limits, equipment fit, and lot-to-lot consistency provide a practical basis for evaluating options.
With the increased complexity of chip structure, there is decreased tolerance in the manufacturing process. Small differences in film thickness, surface condition, or material composition can interfere with the electrical properties that a process is designed to achieve.
Process compatibility matters as much as nominal purity: a material must perform in the specific equipment and sequence in which it will be used.
Advanced semiconductor packaging is adding another layer of demand. Chiplets, high-bandwidth memory, and increasingly dense interconnections require suitable substrates, bonding materials, conductive films, and tightly controlled surfaces.
According to SEMI, packaging materials revenue rose 9.3% to $27.4 billion in 2025, compared with 5.4% growth for wafer-fabrication materials. Higher gold prices contributed to bonding-wire revenue growth, so these figures reflect pricing as well as changes in demand and product mix.
The technical direction is visible in a 2026 research demonstration by imec and EV Group, which achieved wafer-to-wafer copper/dielectric hybrid bonding at a 200-nanometer interconnect pitch on a test vehicle. The work illustrates how materials, surface preparation, and alignment must be developed together, rather than establishing that this capability is already routine in high-volume production.
For manufacturers, new process standards may result in longer evaluation times, additional documentation, and modified procurement specifications. Buying the familiar material at the lowest unit price is less useful if it cannot meet the new process window.
Semiconductor production costs extend well beyond what appears on a materials invoice. A defective film or contaminated lot can trigger extra inspections, equipment downtime, discarded wafers, or investigations that interrupt production.
Not all flaws can be fixed, and those found late in the process can cause major problems.
Consistent materials help engineers maintain stable process settings and isolate the causes of variation. For sputtering operations, material utilization also matters: the amount of target material that can be used effectively, the frequency of target changes, and associated maintenance all contribute to operating expense.
A useful comparison therefore considers total cost of ownership. Procurement teams can track usable output, consumable life, changeover time, waste handling, and the cost of qualifying a replacement.
However, the lowest purchase price does not guarantee the lowest cost per quality device, though any savings must be proved in real-world production settings.
Quality and availability are increasingly linked in the semiconductor supply chain. A technically suitable material offers limited value if delivery uncertainty forces a line to wait or creates pressure to use an unqualified substitute.
Specialized targets and other custom materials may also have manufacturing lead times that are difficult to shorten once demand rises.
The supplier assessment process should include certificates of analysis, lot tracking, inspection techniques, change control, and handling processes. These records help manufacturers investigate deviations and assess proposed replacements, but equivalence must be demonstrated through the qualification work required for the intended process.
Procurement and process engineering should jointly review critical specifications, while quality teams examine testing evidence and corrective-action processes.
Delivery performance, response times, capacity constraints, and contingency arrangements belong on the same supplier scorecard as product conformance.
For especially critical materials, a long-term plan might combine forecast sharing, carefully chosen inventory buffers, and qualification of an alternative source.
Dual sourcing is not an instant fix: introducing a second supplier may require trials, reliability testing, and customer approvals. It is more advantageous to plan for these actions in advance than during a shortage.
Semiconductor production encompasses a geographically dispersed chain of manufacturers and producers of materials and equipment used for the manufacturing process.
Concentration at any critical stage can create exposure to trade restrictions, transportation disruptions, or sudden changes in available capacity.
Qualification requirements make substitution difficult. Even when two suppliers offer the same nominal grade, differences in processing history, geometry, or trace contaminants may require new testing. Long evaluations can therefore delay new entrants and limit buyers’ flexibility.
At the same time, these constraints create opportunities for semiconductor material suppliers able to provide reliable documentation, repeatable specifications, and responsive technical support.
Manufacturers can improve resilience by identifying single-source dependencies, understanding upstream production locations, and reviewing contingency plans with qualified partners.
The aim is not to get rid of all risks. The aim is to stop a predictable risk from becoming an avoidable production disruption.
Start by mapping material specifications against planned capacity expansions, process upgrades, and advanced packaging projects. Identify which inputs have the longest lead times or the fewest qualified alternatives.
Then evaluate suppliers using technical fit, traceability, quality systems, and demonstrated delivery performance rather than unit price alone.
For deposition materials, monitor utilization, film consistency, and replacement frequency so purchasing decisions reflect operating conditions. Revisit these measurements when equipment, processes, or production volumes change.
Finally, bring engineering, procurement, operations, and suppliers into planning discussions early enough to address qualification work before launch dates are at risk.
With advancements in the development of semiconductors, the manufacturers that match material sourcing with the process will have an easier time protecting quality and managing costs.
