Abstract
1503570 Semi-conductor devices SONY CORP 26 March 1975 [28 March 1974 31 Oct 1974] 12697/75 Heading H1K The invention relates to a device as claimed in claim 1 of Specification 1,460,037 in which the impurity concentrations in the regions forming the L-H junction are such as to provide a built-in field of greater than 10<SP>3</SP> V./cm. and a potential barrier greater than 0À1 eV. The embodiments correspond to those in the earlier patent except that the base widths are different.
