1,224,803. Semi-conductor devices. SONY CORP. 26 Feb., 1968 [1 March, 1967 (5)], No. 40776/70. Divided out of 1,224,801. Heading HlK. The subject-matter of this Specification is entirely contained in Specification 1,224,801 but the claims relate to a semi-conductor device comprising a support having a recess in a surface thereof with two sequentially vapour grown semi-conductor layers in said recess lying parallel to its sides and bottom, with semiconductor material filling the portion of the recess surrounded by the layers. The effective width of at least one of the layers at its exposed cross-section at the support surface is greater than the thickness of the bottom portion of that layer in order to facilitate attachment of an electrode thereto.
