发明名称 Apparatus and method for a production testline to monitor CMOS SRAMs
摘要 A semiconductor wafer configured for in-process testing of integrated circuitry fabricated thereon. At least two die are separated by a scribe area, and each of the die has at least one complementary metal oxide silicon (CMOS) static random access memory (SRAM) array embedded therein among mixed-signal CMOS circuitry. The mixed-signal CMOS circuitry includes devices with larger feature sizes compared to similar devices of the embedded SRAM array. A first process control monitor (PCM) testline is included, which has a first layout corresponding to the mixed-signal CMOS circuitry. Additionally, a second PCM testline is included, which has a second layout corresponding to the embedded SRAM arrays. The first and second PCM testlines are formed in the scribe area.
