ABSTRACT:
A cell library is disclosed that includes soft error resistant logic cells. The soft error resistant logic cells can be used along with memory cells and conventional logic cells to form integrated circuit designs having increased soft error resistance. A method for forming an integrated circuit device is disclosed in which a first integrated circuit design is formed using conventional logic cells. An iterative process is then performed in which some of the conventional logic cells are replaced with high soft error resistant logic cells to obtain a soft error resistant design. Each soft error resistant logic cell that replaces a corresponding conventional logic cell will have the same cell size as the cell that is replaced, producing a soft error resistant design that does not take up additional surface area on the semiconductor substrate.
