证券日报网2月25日讯 ，赛微电子在接受调研者提问时表示，在公司看来，每家公司的业务发展模式都 是根据自身的业务情况确定的，公司非常尊重各类厂商（包括客户）自身的战略考虑。但同时公司也应 看到，半导体制造产线的建设具有长周期、重资产投入的特点，且某单一领域设计公司投资建设的自有 产线一方面较难为同类竞争设计公司服务，另一方面产线向其他产品品类拓展的难度也较大。而公司是 专业的纯代工企业，基于长期的工艺开发及生产实践，在同类产品的代工业务方面能够积累较好的工艺 技术，在制造环节具有产品迭代和成本控制方面的服务优势，Fabless（无晶圆厂）模式或Fablite（轻晶 圆厂）设计公司与公司合作，可以避免巨大的固定资产投入，可以将资源更多地专注在产品设计及迭代 方面，并参与市场竞争。综合而言，IDM模式与Fabless或Fablite模式（对应与纯Foundry厂商合作）相 比各有优劣，将会是业界长期共存的商业发展模式。 （编辑 丛可心） ...
