www.shcri.com--The integrated circuit industry is obviously characterized as scaled economy. The larger the enterprises scale, the less the unit production costs and the more helpful to strengthen the competitiveness. The scales of the international integrated circuit giants are expanding continuously. However, Chinese integrated circuit enterprises are all in low yield capacity and small in the scale. Therefore, when numerous domestic manufacturers strive to enhance the technical level, they also formulate the yield capacity expansion plans, standardize the newly built production lines so as to enhance the yield capacity and expand the production scale.
