Title: Reducing radiation effects on integrated circuits
Inventor: SHAW GERARD J
IPC: H01L29/10
Filed: 1986-11-14
Abstract: A semiconductor structure 100 has a bulk semiconductor substrate 112 having a first-type conductivity in a first dopant concentration, on which is epitaxially formed a first semiconductor layer 113 having a first-type conductivity but in a second dopant concentration lower than the first concentration, on which is epitaxially formed a second semiconductor layer 114 having a second-type conductivity opposite to the first-type conductivity and thereby forming a P-N junction with the first layer 113. The thickness of the first layer 113 is greater than the diffusion lengths of electron-hole pairs emitted by the bulk substrate 112 in response to incident radiation so that electron-hole pairs emitted by the substrate 112 are substantially prevented from reaching the P-N junction between the first and second layers 113 and 114, and few electron-hole pairs are emitted by the first layer 113, due to its small thickness, thereby decreasing the effects of incident radiation on active devices formed in the semiconductor structure 100. <IMAGE>
