Introduction and Fundamental Role of the Bulk Terminal == The design of robust parameterized cells (P-cells) for integrated circuit development, particularly for wide, multi-fingered Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs), hinges critically on controlling parasitic elements. Multi-fingered transistors are a common architectural choice in modern very large scale integration (VLSI) design, used primarily to achieve high current driving capabili...") Tag: Visual edit
• 16:0416:04, 12 October 2025 Analysis: Single Bulk Contact vs. Bulk Contact Ring for a FET (hist | edit) [5,577 bytes] Leviathan (talk | contribs) (Created page with "This document analyzes the trade-offs between using a single, small bulk contact versus a continuous bulk contact ring (guard ring) around a Field-Effect Transistor (FET). The choice significantly impacts area, performance, and reliability. === Key Concepts === * '''Bulk (or Body):''' The underlying silicon substrate on which the transistor is built. It must be tied to a stable voltage potential (e.g., VSS for NMOS, VDD for PMOS). * '''Bulk Contact:''' The physical con...") Tag: Visual edit

It is a '''gate-first''' process utilizing polysilicon for the gate electrode and a shallow trench isolation (STI) approach for device isolation. The process is designed for manufacturing the LibreSilicon standard logic cells and is licensed under the Libre Silicon public license. == General Manuf...") Tag: Visual edit: Switched
