liu liu, the project leader of dezhou tianqu new district, has a firm gaze, and he sees the future. he leads the team, from basic technology to product application, step by step to build dezhou into a leader in the semiconductor laser radar industry. they have mastered the core chip technology and laid out the industrialization project of semiconductor laser radar and sensor components. this is not only a milestone in the development of science and technology, but also the driving force of dezhou's economic take-off.

"the production of semiconductor laser radar is like building a house. each process is very complicated. epitaxial production includes hundreds of processes." liu liu explained, "the manufacturing of the sensor's rf chip is the most difficult. the preparation process involves multiple links such as lithography, wet etching, dry etching, doping, chemical vapor deposition, chemical mechanical polishing, and detection and testing. they seem different but repeatedly cross each other. if there is a problem in any link, all the previous efforts will be wasted."

but he knows more clearly that chip semiconductors are one of the most competitive fields in the global industry. mastering core technologies means independent control, which means getting rid of dependence and achieving real breakthroughs. "we have completely achieved domestic substitution and independent control." liu liu said, "through the manufacturing and sales of complete machines, the project can also extend to the upstream and downstream industrial chains, from materials and devices to system module applications."

"the application of lidar started in the field of autonomous driving. it can achieve the safety, comfort and controllability of automobiles, and play a key role in automatic steering and traffic light recognition," liu liu explained. "with the development of internet of vehicles and new energy technologies, the sensitivity and detection distance of the products are becoming more and more accurate, and the development prospects are unlimited."

dezhou's advantages, from its superior transportation location to its government business environment and perfect industrial chain layout, all provide strong support for the project. "after a nationwide inspection, we finally chose dezhou and tianqu new district because, first, it has a superior transportation location and is closest to the beijing r&d center; second, dezhou has a strong foundation in the new generation of electronic information technology industry, which can carry out in-depth cooperation with luxshare precision and yuyuan; third, the main leaders of governments at all levels attach great importance to it and are efficient in handling affairs, which demonstrates a first-class business environment."

it took only three months for the project to be successfully settled. "dezhou was very thoughtful about what we thought of; what we didn't expect was that dezhou also considered it for the company," liu liu said frankly. facts have proved that the choice was right, and the future will definitely be better.

from the promotion of air transportation to the improvement of the industrial chain, texas is becoming an integrated circuit industry landmark with national influence.
