A Collection of Key Items to Know When Looking at the Semiconductor Materials and Components Industry

An overview of materials and components that influence semiconductor quality and yield, including silicon wafers, photoresists, specialty gases, CMP slurries, and package substrates.

When discussing the semiconductor industry, large chip companies and equipment manufacturers often take the spotlight, but the stability of materials and components is crucial in the actual manufacturing process. Items such as wafers, photoresists, specialty gases, slurries, cleaning agents, substrates, and ceramic components directly influence yield and quality. A single material often requires a lengthy certification process before it can be used in customer processes, and any supply disruptions can impact overall production. This list compiles key items that are good to know when examining the semiconductor materials and components industry.

Silicon Wafers

Silicon wafers are the starting point of semiconductor manufacturing. Circuits are created by repeatedly processing a round disk, which is then cut into chips. Factors such as surface defects, purity, flatness, and size of the wafers are critical, and a stable supply of high-quality wafers is necessary for mass production. When semiconductor market conditions improve, the demand for wafers also increases, but customer certifications and long-term contract structures must operate together. It is advisable to consider semiconductor production volumes, client utilization rates, and long-term supply contracts rather than just focusing on simple pricing when examining the wafer industry.

Photoresists

Photoresists are essential materials that react to light in the exposure process to create circuit patterns. After being thinly applied to the wafer, light is shined on it, causing specific areas to undergo chemical changes, thus forming patterns. The EUV process requires higher resolution and defect management, increasing the complexity of the materials. Quality issues with photoresists can directly impact yield, so customer certifications and process compatibility are vital. This item is also frequently mentioned when supply chain issues arise.

Special Gases

Specialty Gases

Specialty gases are essential materials used throughout semiconductor processes. They are employed for etching to remove specific materials, for deposition to form films, and in cleaning and atmosphere control. Semiconductor gases demand very high purity and stable quality, as even minor impurities can affect yield. Different gases are used for different processes, and safety management along with storage and transportation infrastructure is also important. When examining specialty gas companies, it's crucial to assess how deeply they are integrated into customer processes and their supply stability.

CMP Slurry

CMP Slurries

CMP slurries are materials used to flatten the surface of wafers during the Chemical Mechanical Planarization process. As semiconductors are built up in layers to form circuits, it is essential to ensure the surface is uniform at each step. The slurries employ both chemical reactions and mechanical polishing to remove unnecessary parts. Factors such as particle size, chemical composition, and polishing uniformity impact yield and defects. As processes become more complex, the importance of CMP materials increases, necessitating optimization tailored to specific customer processes.

Cleaners and Chemicals

Cleaning Agents and Chemicals

Cleaning agents and chemicals are necessary materials to maintain cleanliness in semiconductor processes. After various processes like exposure, etching, and deposition, residues and contamination need to be removed to ensure the next process is conducted reliably. However, cleaning is not just about intensively washing away; it must preserve necessary layers and patterns while removing only impurities. In fine processes, even minor contamination can lead to defects, making the purity and process compatibility of chemicals crucial. This area can be highly customized to customer processes, and certification periods can also be long.

Photomasks

Photomasks are akin to disks that hold circuit patterns for the exposure process. To imprint the circuit onto the wafer, the designed pattern must be accurately represented on the mask. As processes become more refined, even a single defect in the mask can lead to numerous defective chips, making inspection, repair, and clean management important. In the EUV process, the complexity of mask structure and defect management also increases. Understanding photomasks as a key component that connects design and manufacturing is beneficial.

Package Substrates

Package substrates are crucial components that connect semiconductor chips to systems. They transmit signals and power from the chip to the external board and also support the package structure. As AI semiconductors and high-performance chips for servers grow larger and the volume of power and data transfer increases, the importance of high-performance substrates has risen. Factors such as the number of substrate layers, fine wiring, thermal management, and yield are all important. Package substrates are often mentioned in relation to AI semiconductor demand, as they connect back-end processes with system performance.

Quartz and Ceramic Parts

Quartz and Ceramic Components

Quartz and ceramic components are crucial consumable parts used inside semiconductor equipment. Etching and deposition equipment operate in environments of high temperature, vacuum, plasma, and chemicals, making the durability and cleanliness of internal parts significant. These parts must be replaced after a period of use and can impact equipment utilization rates and maintenance costs. As processes become more refined, contamination or particles originating from components need to be managed more strictly. The equipment component industry is also affected by semiconductor factory utilization rates and process complexity.

While semiconductor materials and components may not be very visible, they are close to the foundational strength of the industry. As advanced processes become more refined, the purity and uniformity of materials, the durability of equipment components, and the performance requirements for package substrates increase. Certain items may have a lengthy customer certification process, potentially becoming barriers to entry; however, one should also consider customer dependence and price negotiation power. When understanding materials and components companies, it's advisable to check which processes their products enter, who their clients are, and whether there are issues related to localization and supply chain stability.
