The domestic production of semiconductors is actually a response to external pressures. After the US-China trade war in 2018, with the US cutting off supplies (such as halting chip supplies to Huawei), we realized how dependent we are on imported high-end chips. The government quickly invested heavily to achieve self-sufficiency, with the National Integrated Circuit … Read more
Metal halide perovskite materials (MHPS) exhibit excellent optoelectronic properties and have broad application prospects in fields such as photovoltaics, light-emitting diodes, and lasers. A key step to fully exploit the potential of these materials is to achieve high-resolution, top-down patterned large-scale chip integration. Developing such a patterning method for perovskite films is challenging due to … Read more

The core capacity is supported by Wolong, … Read more
1 The mask is a key consumable in the photolithography process. The main processes in semiconductor wafer manufacturing include wafer preparation, pattern transfer, material doping, deposition, etching, and packaging. The photolithography process is the core procedure in semiconductor manufacturing, which includes: incoming material cleaning, drying, HDMS adhesion promotion, cold plate, pre-coating baking, cold plate, edge … Read more
Click the blue text Follow us Chips, as the “brain” of modern technology, are ubiquitous from smartphones to aerospace satellites. But did you know? This precision device, the size of a fingernail, originates from unassuming quartz sand. Today, we will unveil the mystery of chip manufacturing and see how it transforms from “sand” into the … Read more
The most challenging aspect of handcrafted circuit boards lies in the wiring of the circuits. Most existing technologies can only utilize planar wiring principles, making it difficult to adopt three-dimensional wiring, indicating that this is also a direction for development. Below is a sound-controlled clap switch circuit, which can be constructed with just thirty components. … Read more
