IC數位晶片簡介
源起
積體電路(IC)為通訊、資訊及消費性電子等3C產業朝向數位化、體積微小化之關鍵性零組件。歷年國內來諸多會議中,均將「提昇國內晶片設計之研究水準,培育晶片系統設計人才」列為重大議題。行政院科技部依據第四次全國科學技術會議之結論,於民國八十一年五月起推動「晶片設計製作中心」(Chip Implementation Center)籌設專案計畫,八十二年一月於新竹科學工業園區成立中心籌備工作小組。八十六年七月有鑑於科技發展趨勢,更名為「國家晶片系統設計中心」。為強化南部高科技研發環境,特於九十一年九月於台南科學工業園區設立南區辦公室,以發展與新竹科學園區相輔相成之前瞻研究,建立高科技技術及產業發展聚落。九十二年元月起為配合國家科學委員會所屬國家實驗室法人化作業,改隸於「財團法人國家實驗研究院」繼續推動各項業務工作。
中心目標
本中心之設立宗旨為「培育積體電路晶片及系統設計人才、提昇積體電路晶片及系統設計技術」,期能強化我國積體電路晶片及系統設計能力。主要任務為:
(一) 建立積體電路晶片及系統設計環境。
(二) 提供積體電路晶片及系統設計雛型品之實作與測試服務。
(三) 推展積體電路晶片及系統設計之「產、學、研」合作研究,並將學術界之研究成果落實推廣至產業界。
(四) 推動國內外積體電路晶片及系統設計相關技術之合作與交流。
