Cutting layout design method suitable for introducing custom chips and chips prepared therefrom

Abstract

The invention discloses a cutting layout design method suitable for introducing custom chips and a prepared chip, belonging to the technical field of semiconductors. Perform typesetting calculation on the upper limit of the circle's operable area, and output all layout design sketches with through-scribing grooves; perform secondary design on the reserved positions in the layout design sketch according to the custom chip data, and output the secondary layout design sketch. In the present invention, the layout design is firstly performed on the conventional chip, and the layout design sketch with the scribing grooves is obtained, which greatly reduces the risk of secondary cutting. The overall change is controlled to a minimum range, and a layout design sketch compatible with custom chips can be obtained without affecting the conventional chip layout, so as to ensure the layout cutting yield and efficiency.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a cutting layout design method suitable for introducing custom chips and a chip prepared therefrom. Background technique [0002] The layout design of integrated circuits plays a crucial role in the design process of silicon-based semiconductors, and is an important intermediate link in the circuit design and the driving process. As the development of silicon-based power semiconductors in China becomes more and more mature, the requirements for high-yield and high-efficiency layout drawing are gradually emerging, and the layout design of silicon-based power semiconductors with stable and reliable, strong process affinity, easy cutting and picking, and high area utilization rate will be quickly obtained. Help further save chip costs, effectively shorten the chip development cycle, and help products occupy the civilian market faster. [0003] The chip form that can directly...
