Fig. 1 shows a semiconductor device structure that has a reduced soft error rate due to alpha-particle radiation when used in semiconductor memories. The essential feature of this structure is the highly doped P+ layer 10 present between the N substrate 11 and P- epitaxial layer 12 which contains the N+ source and drain regions. The P+ layer 10 serves the following purposes:
