Typically, ultra-thin IC substrates are made of some high-performance materials to meet stringent requirements in terms of electrical insulation, mechanical strength, and conductivity.
First of all, the base material of ultra-thin IC substrates is often polyimide (Polyimide) or liquid crystal polymer (LCP). These two materials are popular in the electronics industry mainly due to their excellent properties. Polyimide is a polymer with high thermal stability that maintains its mechanical strength and electrical insulation properties even in high-temperature environments. This makes polyimide an ideal material for use in demanding operating conditions. Liquid crystal polymers are known for their low coefficient of thermal expansion and high chemical resistance, making them excellent in applications requiring high precision and durability.
In addition to the base material, ultra-thin IC substrates also include a layer of conductive metal, usually copper or copper alloys. This is because copper has excellent electrical conductivity and can effectively transmit electrical signals. In addition, copper’s mechanical flexibility and processability also make it ideal for fabricating complex circuit patterns. In certain demanding applications, copper alloys may be selected to further enhance the material’s mechanical strength and durability.
In order to manufacture ultra-thin IC substrates, these materials must undergo a series of delicate processes. First, the polyimide or liquid crystal polymer substrate is prepared into the required thin sheet, and then a uniform layer of copper or copper alloy is plated on its surface through a chemical deposition or electroplating process. Next, precise circuit patterns are formed on the copper layer through photolithography and etching processes. Finally, after drilling and soldering steps, the assembly of the substrate and electrical connections are completed.
The selection of these materials and manufacturing processes for ultra-thin IC substrates not only ensures its high performance and reliability, but also enables it to meet the needs of miniaturization and high-functional integration of modern electronic devices. Whether in high-performance computing, smartphones, wearable devices or other high-tech fields, ultra-thin IC substrates have played an irreplaceable and important role.

From smartphones and wearable devices to industrial equipment and power electronic products, ultra-thin IC substrates are used in various equipment plays an important role in both.
For smartphones and wearable devices, these devices often require small size, light weight, and extremely limited internal space. Therefore, ultra-thin IC substrates must be as small and thin as possible to meet these needs. Such substrates are usually small in size, with thicknesses within a few hundred microns. The small size and ultra-thin nature of these substrates allow them to be easily embedded into tight equipment spaces while maintaining efficient electrical performance and mechanical strength. For example, an ultra-thin IC substrate in a smart watch can be only a few millimeters square, while the thickness may be between 50 microns and 150 microns.
In comparison, industrial equipment and power electronics products have very different substrate size requirements. Such devices usually need to handle higher power and more complex circuits, so the size of ultra-thin IC substrates is relatively large to accommodate more electronic components and more complex wiring. The size of these substrates can reach several centimeters or even tens of centimeters, and although they still maintain ultra-thin characteristics, the thickness is slightly larger than that of consumer electronics to ensure sufficient mechanical strength and heat dissipation capabilities.
In addition, as electronic products continue to be miniaturized and integrated, the flexibility in size and shape of ultra-thin IC substrates has become particularly important. Some advanced application scenarios, such as flexible displays and high-density multi-layer circuit boards, require substrates with higher design freedom. This means that in addition to traditional rectangular and square substrates, ultra-thin IC substrates can also be designed into various complex shapes and sizes according to specific needs to adapt to the internal structures of different devices.
In short, the size of ultra-thin IC substrates is determined based on the needs of specific applications. From tiny smartphone and wearable device substrates to large industrial equipment and power electronics substrates, each application has its specific size and thickness requirements.

The Manufacturer Process of Ultrathin IC Substrate.
The manufacturing process of ultra-thin IC substrates is a highly precise and multi-step process, and each step requires strict control and high-precision operation to ensure the quality and performance of the final product. The following are the main steps in ultra-thin IC substrate manufacturing:
The first step in manufacturing ultra-thin IC substrates is to prepare the substrate materials. Commonly used substrate materials include polyimide (Polyimide) or liquid crystal polymer (LCP), which have excellent electrical insulation properties and mechanical strength. Substrate materials are typically supplied in film form, which is cut and cleaned to ensure a dust-free surface.
After the substrate material is prepared, a layer of copper needs to be deposited on its surface. This is usually achieved by chemical vapor deposition (CVD) or physical vapor deposition (PVD). This process requires precise control of the thickness of the copper layer to ensure it provides good electrical conductivity while maintaining the overall ultra-thin nature.
The next step is photoresist coating and exposure. A layer of photoresist is coated on the substrate, and then the designed circuit pattern is projected onto the photoresist through a mask. After exposure, the photoresist undergoes chemical changes in the areas hit by the light.
After the exposure and development process, only the copper pattern that needs to be retained will be left on the substrate. Next, the copper layer not covered by the photoresist is removed through an etching process. Commonly used etching methods include wet etching and dry etching. Which method to choose depends on the specific design requirements and process conditions.
After etching is complete, holes need to be drilled in the substrate for subsequent electrical connections. These holes can be through holes for through-hole mounting technology (THT) or blind or buried vias for surface mount technology (SMT). Drilling usually uses high-precision laser drilling equipment or mechanical drilling equipment.
After drilling, the electronic components begin to be placed on the substrate. For the SMT process, components are placed directly on pads on the surface of the substrate. For the THT process, the pins of the component are inserted into the substrate through drilled holes and then soldered to the other side of the substrate.
After the electronic components are placed, the next step is soldering. Soldering can be done by reflow or wave soldering, depending on the mounting technique used. Reflow soldering is commonly used for SMT components, while wave soldering is commonly used for THT components.
The final step is testing. Through electrical testing and functional testing, we ensure that each ultra-thin IC substrate meets design specifications and performance requirements. Testing steps include open and short circuit detection, functional testing and reliability testing to ensure the high quality and reliability of the product.
The manufacturing process of ultra-thin IC substrates is a highly complex and precise process that requires multi-step precise operations and strict control. Every step, from substrate preparation to final testing, is critical to product quality and performance. By optimizing each manufacturing step, we ensure that the final ultra-thin IC substrate has excellent electrical properties and mechanical strength to meet various application needs.
