Semiconductor production line building process and deal with the problem

Build a new plant means that the time, money and resources on the company's huge investment. The success of the entire company may depend on the new plant ROI (ROI). To achieve the maximization of ROI, need to be weighed against a number of factors, from the initial plant design to the later stages of the production volume.

Overall, factory planning and construction began in the general questions, and then the specific details. In the beginning, the designer must understand this plant will produce how many wafers per month, which is the number of dimensions of the wafer, and the use of what the design rules and process technology. However, the production capacity, wafer size and the best combination of technology depends on the plant began production of market conditions, but this time from the original factory planning often been a long time.

When to plant

From the construction of a factory on the amount needed to produce more than two years time. However, the technological leap about once every 18 months alone, semiconductor sales peak every 24 to 36 months once. For two years after the future, regardless of the technology roadshow or market forecasts are insufficient data. If the production of products whose technology has entered a recession, the financial position of the company will have disastrous consequences.

DRAM industry for production planning and famous. In general, when DRAM prices to remain stable for some time, or continued to rise and demand, there will be many factories mushroomed come up. The first batch of new factories to join the ranks of suppliers, resulting in an increase in sources of supply and lower prices; while the latter opened factories are facing more severe price competition. 1996 to 1997, the price of memory fell below the cost of its production, in 2001 re-emergence of this situation.

These huge financial risk warning people to take a relatively conservative investment programs. However,OLED Display investment in the expansion strategy of the company to maintain a positive growth in the demand for more rapid time to market the product up. Large production capacity DRAM suppliers can take advantage of market price fluctuations for their own profit. Contribute to higher value-added production capacity chip (such as microprocessors) suppliers from the price gain additional profits.

On the contrary, can not meet the demand for chip suppliers are likely to lose sight and future orders. And in turn, limit orders to reduce future capital expenditures and the Company's growth and development.
Technology continues to develop production capacity also makes the planning becomes more complex. More highly entrepreneurial design rules can be in a smaller package to achieve higher performance, and unit costs are generally lower. Higher performance can be obtained from the price of additional profits. For a technologically advanced facility, it is the first 18-month earnings situation best and can quickly earn back the initial investment stage. The use of relatively old technology factory price is not possible to earn extra profits. Moreover, compared with the more advanced plants, the cost of the disadvantages is a reality.

However, Lcd display modules the technological leap will also bring risks. The new manufacturing tools may not satisfy the requirements of program delivery, can not immediately meet the requirements of mass production or can not produce the desired process performance. Hysteresis loss will technically important market plant. The closer a company cutting edge of technology, the greater the risk technically. For many companies, alliances or joint ventures to help reduce business and technical risks.
