If the lithography machine Kirin 9000 is not available, other alternatives may be taken to produce chips. Here's a possible alternative:
< br >
1. Choose other lithography machines: Lithography machines are one of the key equipment in chip manufacturing, which is used to project chip design patterns onto silicon wafers. If there is no Kirin 9000, you can choose the lithography machine produced by other manufacturers, such as ASML, Nikon, Keme and so on.

2. Use lower process nodes: Kirin 9000 is an advanced lithography machine developed by Huawei for manufacturing high-performance chips. If this model is not available, you can choose to use an older lithography machine or use a lower process node to manufacture the chip, although the performance may be reduced.

3. Cooperation or outsourcing production: If you cannot obtain suitable lithography machines or technology, you can consider cooperating with other companies or outsourcing the production of chips, using their equipment and technology to complete the manufacturing process.
