Advanced semiconductor packaging substrate

Advanced semiconductor packaging substrates are a key component in semiconductor packaging technology and are used to support, connect and protect semiconductor components on the chip. These substrates play an important role in modern electronic devices and chip packaging, especially in high-performance and complex applications.

Basic functions

Semiconductor packaging s

ubstrates mainly have two basic functions. First, they provide a mechanical support structure that holds the chip in the package to prevent physical damage. Second, they provide electrical connections to the semiconductor components on the chip, connecting the chip to external circuitry.


These substrates are usually made of high-performance materials such as Si, GaN, AlN or ceramics. Material selection depends on application requirements such as thermal conductivity, electrical properties and packaging environment.

Packaging Substrate

Multi-layer structure

In complex applications, semiconductor packaging substrates often adopt multi-layer structures. These multiple layers include electrical, insulating, and thermal layers to ensure reliable transmission of electrical signals, isolation, and thermal performance.

Electrical connections

Electrical connections on a substrate typically consist of wires, pads, connections, and electrical traces that connect the pins on the chip to external circuitry. These connections must meet high-frequency signal transmission and low signal-to-noise ratio requirements.
Heat dissipation performance: High-performance semiconductor packaging substrates also have excellent heat dissipation properties to effectively dissipate the heat generated by the chip and prevent overheating from damaging semiconductor components.

Technological Advances

Advanced semiconductor packaging substrates are an area that continues to evolve to meet the needs of new generations of chips and electronic devices. New technologies include higher-density interconnects, better heat-dissipation materials, more refined manufacturing processes, and three-dimensional stacking of packaging substrates.

Application fields

Advanced semiconductor packaging substrates play a key role in fields such as high-performance computing, communication equipment, automotive electronics, artificial intelligence, and the Internet of Things, as these fields require higher performance and reliability of semiconductor components.

What is a Package Substrate?

“Package substrate” is a term widely used in the fields of electronic engineering and electronics manufacturing, often used to refer to the base plate used for IC packaging of electronic components. Its main function is to provide mechanical support, electrical connections and heat dissipation to protect and connect integrated circuit chips.
The following is a detailed introduction to the packaging substrate:

Mechanical support

Package substrates are often made of strong materials such as ceramics, resins, or metals to provide mechanical support. This helps protect the chip from physical damage such as vibration, shock and pressure.

Electrical connections

The package substrate is usually integrated with wires, solder joints, and connectors to connect the chip and other electronic components to the circuit board or circuit system. These connections can be solder joints, sockets, connectors or other electrical connection technology.

Heat dissipation

Some package substrates are also designed with heat dissipation functions to help the chip cool down during operation. High-performance integrated circuits may generate large amounts of heat, which may affect their performance and lifespan if not properly dissipated. Thermal design can include heat sinks, thermal pads, thermally conductive materials, etc.

Packaging type

There are many types of packaging substrates, including double-sided substrates, multi-layer substrates and flexible substrates. Each type is suitable for different applications and needs. For example, multilayer substrates have multiple layers to accommodate more electrical connections and signal layers, while flex substrates are made of flexible materials and are suitable for curved or curved applications.

Package Size

The size and shape of the package substrate can be customized to meet the needs of a specific application. Some package substrates are small and suitable for micro packages, while other package substrates are larger and suitable for large packages.

Packaging substrates process capability

Packaging substrate process capability refers to the manufacturer’s ability to ensure that the product meets certain standards and specifications during the production process of packaging substrates. It covers many aspects, including process control, quality management, technical capabilities and innovation capabilities, etc.

Process control

The manufacturing process of packaging substrates requires strict control of the process, including raw material selection, production equipment operation, process parameter control, etc. Good process control can ensure the stability and reliability of product quality.

Quality management

Quality management is crucial in the packaging substrate process, involving the entire process control from raw material procurement to finished product delivery. It includes quality testing, quality control and quality improvement, etc., aiming to ensure that products meet specification requirements and provide stable and reliable performance.

Technical capabilities

Packaging substrate manufacturing requires a high level of technical capabilities, including expertise in materials science, process engineering, equipment technology, etc. Manufacturers need to constantly update technology to respond to changes in market demand and provide competitive products.

Innovation capabilities

Packaging substrate process capabilities also require continuous innovation capabilities to adapt to evolving market demands and the emergence of new technologies. This may involve the application of new materials, the development of new processes, and the design of new products to improve product performance and competitiveness.

Sustainable development capabilities

In today’s context of concern about environmental protection and sustainable development, packaging substrate process capabilities also include meeting environmental protection requirements and paying attention to sustainable development. Manufacturers need to focus on energy conservation, emission reduction, waste disposal and environmental protection to meet social requirements for environmental protection.

Price and delivery date of packaging substrate

Price: The price of packaging substrates refers to the monetary cost of purchasing those substrates. Price can be affected by a variety of factors, including but not limited to the following:
Quantity: Generally speaking, purchasing higher quantities of package substrates may result in greater discounts, as production costs typically decrease with higher volume. The higher the quantity purchased, the lower the cost per substrate is likely to be
Specifications and quality: Package substrates of different specifications and quality may have different prices. High-performance, high-quality substrates typically cost more.
Suppliers: Different suppliers may have different pricing strategies, so prices will vary from supplier to supplier. Sometimes, suppliers with a long history of cooperation may offer more competitive prices.
Special customization needs: If a custom packaging substrate is required, such as special dimensions, materials or processes, this will usually result in a higher price as it requires additional engineering and production costs.

Delivery Date: The delivery date is the date when the package substrate will be delivered to the buyer. This date is usually clearly defined in the purchase contract, which is an agreement between the supplier and the buyer. Delivery dates are affected by:
Stock Availability: If the package substrate is available in the supplier’s inventory, the delivery date may be faster. But if customization or high-volume production is required, the delivery date may be delayed.
Production Time: The time required to produce a package substrate affects delivery dates. Production time is affected by order quantity, process complexity and production capacity.
Shipping Time: Delivery dates are also affected by the shipping time required from supplier to buyer. This may vary based on geographic location and shipping method.
Urgent demand: If the buyer has urgent demand, expedited production and delivery may be required, but this usually comes with additional costs.
