Single crystal thin film is one of the basic raw materials for the preparation of various optical chips and information storage devices
Recently, the company received strategic investment from Huawei…
JNJZ Electronic Materials Technology Corporation is committed to the R&D and production of nano-scale lithium niobate single crystal thin films, and is known as the most ideal choice for optical communication equipment in the industry.
Compared with mainstream chip materials such as single crystal silicon and single crystal vanadium dioxide, what are the advantages of lithium niobate?
Curie temperature is the highest
Lithium niobate is a negative crystalline compound composed of niobium, lithium and oxygen. From a chemical point of view only, among the special electrode materials that have been discovered, lithium niobate has the highest Curie temperature, which can reach 1210 °C.
The so-called Curie temperature refers specifically to the temperature node at which the magnetism of a certain compound disappears. As we all know, the existence of electromagnetic effect is the technical prerequisite for the chip to play the semiconductor function. Therefore, the higher the Curie temperature, the more stable the magnetic performance of the compound. The Curie temperature property of lithium niobate determines that it is indeed worthy of the title of "mainstay" of single crystal thin films.
Excellent photoelectric performance
Derived from the ultra-high Curie temperature, the two characteristics of the lithium niobate single crystal thin film make it the best material choice for optical communication core devices:
First of all, there are many photoelectric effects. A lithium niobate crystal has various photoelectric properties such as piezoelectric effect, photoelastic effect, photorefractive effect, nonlinear optical effect, and photoacoustic photovoltaic effect. The distortion processing of lithium niobate crystals and the performance of various optoelectronic properties can also be precisely controlled.
In a word, the single crystal thin film processed from lithium niobate crystal has extremely low chirp effect, excellent optical extinction ratio and excellent stability, and has natural advantages that cannot be replaced by any other material in ultra-long-distance communication.
As early as 1964, Bell Labs in the United States began to study the characteristics of lithium niobate semiconductors. In the following ten years, European and American scientific research teams have blossomed more and more, and successively established the lattice structure of lithium niobate in the ferroelectric and paraelectric phases, and made important breakthroughs in the material growth process, but only in lithium niobate single crystal The production of thin films has fallen into a bottleneck.
After tens of thousands of experiments, JNJZ finally took the lead in developing nano-scale lithium niobate single crystal thin films through the combined application of ion implantation, direct bonding and other technologies.
The company took the lead in developing and industrializing 300-900 nanometer thickness lithium niobate single crystal thin film materials in the world.
The company's products cover a variety of high-tech and high-standard crystalline thin film materials, which can be used to make high-performance modulators, filters, detectors, crystal oscillators and high-density information storage devices. , infrared detection and other fields have broad development prospects and significant application advantages, which can bring huge economic and social benefits.
Under the processing technology of JNJZ, 0.5 mm thick lithium niobate single crystal can be cut into 1000 thin film wafers in parallel.
At present, JNJZ has accumulated more than 100 patents on the manufacturing process of lithium niobate thin film, and has also built the world's first lithium niobate thin film manufacturing base.
