In 2026, the chip market is very lively, and popular fields such as GPU and computing chips have attracted a lot of attention.
However, one type of seemingly ordinary material – high-end electronic ceramics – is quietly changing.
90% of retail investors have fallen into the misunderstanding of chasing popular chips and look down on ordinary ceramic materials like ceramic tiles, thinking that they are unpopular and unmarketable.
But in fact, the trend of the chip packaging industry has changed, and high-end electronic ceramics have experienced a substantial turnaround.
First of all, we need to subvert the inherent understanding of ceramic materials.
Ceramic tiles and dishes used for home decoration are ordinary civilian products, while high-end electronic ceramics used for semiconductor packaging have similar appearances, but are actually completely different.
The high-power chips in the AI server generate a lot of heat when running, and ordinary plastic packaging materials can no longer meet the demand.
Aluminum nitride ceramic substrates and ceramic casings have the characteristics of strong thermal conductivity, high temperature resistance, and good insulation, and are the basic carriers of high-end chip packaging.
Many retail investors ignore this “hidden, invisible, urgently needed material”, which is the biggest cognitive blind spot.
At present, the strength of ceramic packaging materials has its real logic of rigid demand.
First, downstream demand is actually growing.
AI computing servers continue to expand, shipments of high-speed optical modules, high-power computing chips, and new energy power chips have steadily increased, and the usage and quality requirements for high-end ceramic packaging materials have also increased simultaneously.
The inventory of downstream head packaging and testing and optical module companies continues to increase, and real procurement demand continues to be released.
Second, overseas supply has shrunk.
For a long time, high-end aluminum nitride ceramic substrates have been mainly supplied by Japanese companies.
Recently, due to the impact of raw material supply and production line adjustments, overseas high-end production capacity has been reduced and delivery cycles have been significantly lengthened. The global supply of high-end high-quality ceramic substrates has begun to become tight.
For the sake of supply chain security, downstream customers actively turn to verify and purchase domestic ceramic materials, opening the window for domestic substitution.
Third, the overall industry cycle of semiconductor packaging is picking up. The operating rate of downstream packaging and testing factories has steadily picked up. The overall willingness to purchase has become stronger. Coupled with the long-term industry orientation of independent and controllable supply chains, the overall inflection point of the industry has gradually emerged, and the ceramic segment has ushered in dual opportunities for volume increase and replacement.
The supply-side threshold is extremely high and scarcity is prominent.
The production of high-end semiconductor ceramics ranges from high-purity ceramic powder proportioning, molding and sintering, precision machining, to passing the long-term and strict supply chain verification of major chip manufacturers. The entire process technology accumulation period is long, R&D investment is large, and the yield rate is difficult to control. It is difficult for novice companies to enter the market in a short period of time.
At present, the overall localization ratio of domestic high-end semiconductor packaging ceramics is low, and overseas supply restrictions coupled with downstream transfer orders have left a large substitution gap, and orders continue to be tilted towards high-quality domestic companies.
In the past, the performance of domestic high-end ceramic powders and precision ceramic substrates was unstable and the verification pass rate was low. Domestic companies could only operate in the low-end ordinary ceramic market.
However, after years of R&D and polishing, the high-purity ceramic powder formulas and sintering processes of domestic leading companies have gradually matured, and product performance has benchmarked against imported levels. They have successively passed the long-term supply chain verification of leading optical module and packaging and testing manufacturers, and have transitioned from small batch trials to large batch stable supply. Domestic high-end ceramics have officially entered a critical turning point for mass substitution.
Here are three core leading companies.
China Ceramics Electronics is a benchmark enterprise for high-end optical communication ceramic packaging in China. It has profound technological accumulation and has formed a high-end dual supply pattern with overseas leaders. A large number of high-end orders have been locked in, and its production capacity continues to operate at full capacity.
Sanhuan Group has opened up a complete production chain integrating ceramic powder formula, substrate sintering, and precision ceramic packaging base. It has the world’s leading share of alumina ceramic substrates and strong risk resistance.
China Ceramics Materials is a leading company in high-purity electronic ceramic powders. It not only supplies high-quality ceramic powders to the outside world, but also extends its semiconductor heat dissipation ceramic substrate business, and has strong operational stability.
In the short term, as the packaging industry picks up and overseas supply tightens, domestic high-end ceramics will usher in periodic dividends from switching orders and increasing sales; in the long term, with the continued construction of AI computing power, the expansion of new energy vehicle power chips and the long-term direction of independent supply chain substitution, the long-term demand for high-end semiconductor ceramics will steadily increase, and the growth dividends of domestic substitution will continue to be released.
Retail investors do not need to frequently keep an eye on the hype on the disk. They only continue to pay attention to the stocking and expansion of downstream head optical modules and packaging and testing manufacturers, as well as the new verification and production expansion announcements of domestic ceramic head companies, to avoid the short-term fluctuation trap of pure news speculation.
