The COM2 SiGe modular BiCMOS technology has been developed to allow efficient design and manufacturing of digital, mixed-signal, and RF integrated circuits, as well as enabling system-on-chip (SOC) integration. The technology is based on the 0.16pm COM2 digital CMOS process which features 1.5V NMOS and PMOS transistors with 2.4nm gate oxide, 0.135pm gate length, and up to 7 metal levels. Technology enhancement modules including dense SRAM, SiGe NPN bipolar transistor, and a variety of passive components have been developed to allow the COM2 technology to be cost-effectively optimized for a wide range of applications.

Background Adherence to ethical guidelines and regulations and protecting and respecting the dignity and autonomy of participants by obtaining a valid informed consent form (ICF) prior to participation in research are crucial; The subjects did not add signatures next to the corrections made to signatures or dates on the ICF, Multiple signatures in other fields, ICF missing/missing signature, Incorrect ICF version Signed after modification, Correction tape used to correct signature, Impersonated signature, Non-research-member signature, however, ICFs are often not properly completed, which must be addressed. This study analyzed ICF signing errors and implemented measures to reduce or prevent these errors. Methods We used the plan–do–check–act (PDCA) cycle to help improve the correctness and validity of ICF signing. Results Interim and final reports from January 2016 to February 2020 including 363 ICFs were studied. The total proportion of correct ICF signatures (200, 83.3%) following the PDCA intervention was significantly higher than that before the intervention (P < 0.05). Analysis of the types of signing error demonstrated that signature errors were significantly reduced after the intervention, particularly for subjects did not add signatures next to the corrections made to signatures or dates on the ICF (16, 6.7%) and impersonated signature (0; P < 0.05). Conclusions The proportions of other error types—multiple signatures in other fields, missing or unsigned ICF, incorrect signature order, incorrect ICF version, use of correction tape to correct signature, and non-medical profession members signing the ICF—did not differ significantly.
