本研究的主要目的在於透過分析台積公司(台灣積體電路製造股份有限公司)的電阻式隨機存取記憶體(RRAM)技術之美國專利文件,以進行台積公司的電阻式隨機存取記憶體之技術功效與趨勢研究。
首先,本研究分析RRAM技術美國專利概況,即檢索美國專利商標局之公開資料庫與公告資料庫的RRAM技術專利,並分析RRAM技術的美國專利申請趨勢、美國專利核准趨勢、前五大專利申請人、前五大專利申請人的申請與核准趨勢。接著,本研究從主要專利申請人中選定「台積公司」作為分析目標,找出台積公司的RRAM技術美國專利的專利文件,並透過逐篇人工閱讀上述專利文件,以解析台積公司針對RRAM技術在美國專利商標局所申請的專利的八個技術類別以及十二個功效類別。再者,本研究根據上述各個技術與功效類別,製作台積公司之RRAM技術的美國專利技術功效矩陣、基於合作專利分類(CPC)之技術功效矩陣、功效發展趨勢圖,並進行相關分析。最後,本研究統整上述研究結果,並提出針對台積公司的RRAM技術之研發建議以及未來研究方向。
本研究獲得以下結論:
RRAM技術的研發相當熱絡,且將逐漸被重視。
RRAM技術美國專利的主要專利權人集中在具有一定規模的公司。
僅使用CPC四階分類碼來進行技術解析之效果不夠顯著,參考價值有限。
台積公司現階段重視RRAM結構技術的專利佈局高於方法技術的專利佈局。
台積公司針對RRAM技術所研發的功效逐步全面化,且其功效熱點至少包含:縮小尺寸、改善資料保留力、改善可靠性、預防裝置故障、改善效能、預防裝置損壞、改善製程。
台積公司的主要競爭公司至少包含三星電子(Samsung Electronics)、國際商業機器公司(IBM)、SK海力士半導體公司(SK Hynix Semiconductor),其中IBM往後對台積公司可能更具競爭性。
The main purpose of this study is to analyze the US patent documents of Resistive Random Access Memory (RRAM) of TSMC (Taiwan Semiconductor Manufacturing Co., Ltd.) for TSMC’s technology-function analysis and trend study in RRAM technical field.
First, this study analyzes all US patents of RRAM technology, i.e., searches the RRAM technology patents from the USPTO Patent Application Full-Text and Image Database (AppFT) and USPTO Patent Full-Text and Image Database (PatFT), and analyzes the trend in US patent applications, trend in US patent grants, and the top five patent applicants, and the trend in US patent applications and grants of the top five patent applicants of RRAM technology. Next, this study selects “TSMC” from the main patent applicants as the analysis objective, manually reads each US patent document of TSMC to determine the eight technical categories and the twelve functional categories of the RRAM technical field according to the US patent documents. In addition, based on each technical category and functional category, this study also produces a technology-function matrix of TSMC’s US patents in RRAM technical field, a technology-function matrix based on Cooperative Patent Classification (CPC), and a trend in function development. Finally, this study summarizes the above research results and proposes advices for researching and developing RRAM technology for TSMC, as well as future research directions.
The following are the conclusions obtained in this research:
The research and development of RRAM technology is currently popular and will gradually be valued.
The main US patent applicants of RRAM technology are likely to be companies with large scale.
The result and the reference value for technical analysis by merely using the fourth-level of CPC is not ideal.
TSMC currently invests more in patnet portfolio for RRAM structure than for RRAM method.
The functions developed by TSMC for RRAM technology are gradually being comprehensive, and the important fuctions at least includes: reducing device size, improving data retention, improving reliability, preventing device failure, improving performance, preventing device damage, and improving manufacture.
The main competitors of TSMC at least include: Samsung Electronics, International Business Machines Corporation (IBM), and SK Hynix Semiconductor, wherein IBM is likely to become more competitive in the future.
