Process Documentation for tsmc's 0.18um BCD process

Hello, does anyone know where to find the Process Documentation for tsmc's 0.18um BCD process ? Is this an official data sheet-like document from TSMC? Does anyone, by any chance, know if there exists any third party documentation for this process, say authored by some cool electronics engineer dude that took the effort to go into the details and explain the whole 0.18um BCD Library? For example explaining how the Library is split up into it's categories, and then exactly what kind of devices are available in each category and so on...

Just a few quick query-examples:

In the Categories of the Library there are 2 categories for MOSFET devices, namely:
1. LV_MOS_FULL_TERM (which has a bunch of devices but with a not so clear description as to what each device actually is)
2. Mosfets: this one has 2 sub categories: Mosfet_HV & Mosfet_LV, which obviously stand for High Voltage and Low Voltage devices respectively BUT inside of each there are sooo many different devices! Where can one read about each one of these devices in order to understand when and how to use one and not the other ?

For example, here are some device names from the Mosfet_HV sub category:

na6_g5a_nbl_mac

na45_g5b_mac

nda20_g3a_mac

nld16_g5a_iso_mac

pa8_g5a_nlb_mac

What do all these: "na6" "g5a"/"g5b" "nbl" "nld16" "iso" "mac" ....parts of the device names mean?

Thank you in advance for any advice/info!
