BCD DEVICE LAYOUT AREA DEFINED BY A DEEP TRENCH ISOLATION STRUCTURE AND METHODS FOR FORMING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240021601 titled 'BCD DEVICE LAYOUT AREA DEFINED BY A DEEP TRENCH ISOLATION STRUCTURE AND METHODS FOR FORMING THE SAME
Simplified Explanation
The abstract describes a semiconductor structure for use with bipolar-cmos-dmos (BCD) devices, specifically focusing on a deep trench layout area-saving structure. The structure includes a deep trench isolation structure that defines the layout area of the BCD device, with rounded corners and specific intersections.
- The semiconductor device includes a first BCD device formed within a first perimeter of a BCD layout area.
- The deep trench isolation structure surrounds the first BCD device and defines the first perimeter of the layout area.
- The deep trench isolation structure has a first rounded corner that defines a first corner of the layout area.
- The deep trench isolation structure consists of vertical and horizontal portions, as well as a "T"-shaped intersection and a cross-shaped intersection.
Potential applications of this technology:
- This semiconductor structure can be used in the manufacturing of BCD devices, which are commonly used in power management applications.
- It can be utilized in the production of integrated circuits for automotive electronics, consumer electronics, and industrial applications.
- The deep trench isolation structure helps improve the performance and reliability of BCD devices by reducing parasitic capacitance and improving isolation between components.
Problems solved by this technology:
- The deep trench isolation structure solves the problem of limited layout area in BCD devices by providing an area-saving design.
- It addresses the challenge of reducing parasitic capacitance and improving isolation between components, which can affect the performance and reliability of BCD devices.
Benefits of this technology:
- The deep trench isolation structure allows for more efficient use of layout area, enabling the integration of more components in a smaller space.
- It helps improve the performance and reliability of BCD devices by reducing parasitic capacitance and improving isolation between components.
- The structure provides a cost-effective solution for manufacturing BCD devices with enhanced functionality and performance.
