POWER MANAGEMENT INTEGRATED CIRCUIT AND SEMICONDUCTOR PACKAGE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18110488 titled 'POWER MANAGEMENT INTEGRATED CIRCUIT AND SEMICONDUCTOR PACKAGE INCLUDING THE SAME
Simplified Explanation
The abstract describes a power management integrated circuit that includes a buck converter with two metal oxide semiconductor field effect transistors (MOSFETs) of different conductivity types. The first MOSFET is arranged in transistor sets, each consisting of source regions, drain regions, and gate electrodes. The source and drain regions have an impurity region of the first conductivity type, and the source regions also have segment regions of the second conductivity type. The first and second source regions are spaced apart in a first direction, and the number of segment regions in each source region differs.

Original Abstract Submitted
A power management integrated circuit includes a buck converter that includes a first metal oxide semiconductor field effect transistor (MOSFET) having a first conductivity type and a second MOSFET having a second conductivity type. The first MOSFET includes transistor sets that are two-dimensionally arranged. Each transistor set includes source regions, drain regions, and gate electrodes between the source regions and the drain regions. Each source region and each drain region includes an impurity region having the first conductivity type, and each source region further includes segment regions having the second conductivity type. A first source region is spaced apart from a second source region in a first direction, and a number of the segment regions in the first source region is different from a number of the segment regions in the second source region.
