In this work, we implement a 2nd DB-aware timing and leakage analysis 2nd flow, and show how a lack of DB awareness can misguide cur-rent optimization in place-and-route stages. We then develop 2nd. DB-aware leakage optimization and detailed placement heuristics.

Apr 19, 2024 · Smart Diffusion Break (SDB) is a technique utilized in semiconductor fabrication to enhance the performance and efficiency of FinFET transistors. In the context of Samsung’s foundry processes, SDB involves strategically placed breaks in the diffusion process.

*.sdb - Symbol Library. This is a compiled version of *.slib in Synopsys database format.

Single diffusion break (SDB) is a promising option to reduce die area with STI width of 1 gate length illustrated in Fig. 1 (b), but a heavy facet of source/drain (S/D) epi at edge of STI

Jan 21, 2019 · In foundry sub-10nm design enablements, device performance is changed according to the type of DB - single diffusion break (SDB) or double diffusion break (DDB) - that is used in the library cell layout. Crucially, local layout effect (LLE) can substantially affect device performance and leakage.

[click] There are two types of diffusion break: single diffusion break, or SDB, and double diffusion break – DDB. [click] SDB cells have lower speed and leakage, and smaller area, while [click] DDB cells have higher speed and leakage, with larger area.

In this paper, the 3 main SDB approaches, including fin/STI approach, ILD approach and HKMG approach, are investigated systemically by virtual fabrication with Coventor SEMulator3D®. We find unique advantages and disadvantages present for each approach.

Single diffusion break (SDB) devices in FinFET technology are desirable and attractive for their minimum footage in aggressively scaled circuits. This paper reports fin-shape optimization efficiently improved SDB PFET device performance by up to 9%.

Jun 1, 2007 · 2. a .sdb file for symbol library. in back end (for example soc encounter) you need at least these files: 1. timing libraries(.lib files) 2.physical libraries of standard cells(.lef files) 3.timing constraint file(.sdc file created in design vision) 4.io assignment file(you can create yourself)

Jun 25, 2022 · In Single Diffusion Break (SDB), space for a single separation gate is replaced by a deep etched insulator material which cuts the fins and isolates the active areas. This takes up less horizontal width than DDB, contributing to DTCO area scaling.
