STANDARD CELLS WITH MULTI-WELL SIZE PLACEMENTS

This abstract first appeared for US patent application 20250120184 titled 'STANDARD CELLS WITH MULTI-WELL SIZE PLACEMENTS

Original Abstract Submitted

a semiconductor structure includes first standard cells having first active regions formed over first alternating n-type and p-type wells, the first active regions and the first alternating n-type and p-type wells each extends lengthwise along a first direction, each of the first standard cells includes a first n-type well and a first p-type well; and second standard cells adjacent to the first standard cells, the second standard cells having second active regions formed over second alternating n-type and p-type wells, the second active regions and the second alternating n-type and p-type wells each extends lengthwise along the first direction, each of the second standard cells includes a second n-type well and a second p-type well. the first standard cells have a first cell height, the second standard cells have a second cell height, and the second cell height is greater than the first cell height.
