Advanced packaging into a new breakthrough for domestic lithography machines
"2022 will be the first year of advanced packaging." The giants continue to increase their weight, so that this recognition is becoming the consensus of the industry. And this vast blue ocean that is slowly unfolding brings not only new opportunities, but also new challenges, and the challengers are far more than foundries and packaging and testing factories.
The food and grass are not moved, and the equipment is first. Higher connection density and more precise control are the advantages of advanced packaging over traditional packaging, and it also puts forward new requirements for the equipment used. Due to the introduction of bump, TSV and other technologies, advanced packaging is moving infinitely closer to the front-end manufacturing process. As the "crown jewel" of the equipment field, lithography also plays a crucial role in advanced packaging.
In this context, lithography equipment giants at home and abroad have all added advanced packaging, and China, as the current global semiconductor industry transfer position, is the country with the largest production capacity of semiconductor packaging and testing, and leading domestic lithography equipment manufacturers have demonstrated. Among them, the launch of WLP-8, a maskless direct-writing lithography equipment for Microchip, represents a new journey for domestic lithography machines.
The blue ocean of advanced packaging is now a prelude to the domestic lithography machine
Dr. Qu Lujie, deputy general manager of Core Microelectronics, said that with the end of Moore's Law, problems including resolution, power consumption, transmission speed, etc. need to be solved by advanced packaging, wafer-level packaging, including 2.5D/3D packaging , In fact, it is to solve the interconnection problem between chips, and as a higher-density chip, it plays a key role in chip performance.
According to Yole, a market research agency, the advanced packaging market will grow to US$44 billion at a compound annual growth rate of 8% from 2018 to 2024, exceeding the 5% compound growth rate of the overall packaging in the same period and much higher than the 2.4% growth rate of traditional packaging in the same period. compound growth rate. The proportion of revenue in the overall packaging has also increased year by year, from 42.1% in 2018 to 49.7% in 2024.
According to reports, the
WLP-8 maskless direct writing lithography equipment is used in mass production direct writing lithography equipment in the fields of wafer level packaging, system level packaging, board level packaging, power devices, discrete components and other advanced packaging and chip manufacturing fields , The lithography accuracy can reach the minimum line width of 2μm, the production capacity is 30-60 pieces/hour, it supports the RDL function of advanced packaging and chip manufacturing, and is suitable for use in mass production lines such as pilot test and production.
Looks like advanced packaging is becoming more serious, mask-less direct writing lithography could be a complementary solution to the higher density more precise mask optical lithography equipment.
