Features

According to Maxim website, it is an innovative process characteristics that provides the following features:

1. high break-down voltage
   Voltage
   Voltage, otherwise known as electrical potential difference or electric tension is the difference in electric potential between two points — or the difference in electric potential energy per unit charge between two points...
   
    but small transistor
   Transistor
   A transistor is a semiconductor device used to amplify and switch electronic signals and power. It is composed of a semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current...

2. quite low on-resistance, which is important for the integration of multiple power FET
   Field-effect transistor
   The field-effect transistor is a transistor that relies on an electric field to control the shape and hence the conductivity of a channel of one type of charge carrier in a semiconductor material. FETs are sometimes called unipolar transistors to contrast their single-carrier-type operation with...

4. combining thin film and poly-poly caps (in silicon). High-accuracy references can be integrated.

According to Dongbu HiTek's news, it claims to launch the first 0.18-micrometre BCDMOS process in industry. The new process integrates logic

Logic

In philosophy, Logic is the formal systematic study of the principles of valid inference and correct reasoning. Logic is used in most intellectual activities, but is studied primarily in the disciplines of philosophy, mathematics, semantics, and computer science...

Analogue electronics

Analogue electronics are electronic systems with a continuously variable signal, in contrast to digital electronics where signals usually take only two different levels. The term "analogue" describes the proportional relationship between a signal and a voltage or current that represents the signal...
