A first terminal of the OTP fuse includes a first conductive pillar through one of the first and second insulator layers and in contact with the TFR layer; and a second terminal of the OTP fuse includes a second conductive pillar through one of the first and second insulator layers and in contact with the TFR layer.

The second conductive pillar does not simply land on the TFR layer, but extends through it. Application of a current to the OTP fuse results in programming via rupture of the lateral contact interface (not electromigration in the fuse link).

Abstract: Disclosed are a system and method for automatically and systematically generating device-based design rules and corresponding device-based design rule checking (DRC) codes. In the system and method, design rules associated with specific devices are generated based on at least one table of related data (e.g., maturity status information, restriction status information, etc.) for different devices.
