<p>1532286 Matrix displays ELLIOTT BROS (LONDON) Ltd 23 Sept 1977 [7 Oct 1976] 41744/76 Heading G5C [Also in Division H1] In the manufacture of an array of LEDs each of which comprises a separate p type diffusion 3 into an n type substrate 1 and in which individual diodes are contacted, and preferably interconnected in rows, on their top surfaces and a common electrode 2 is applied over the entire lower surface, lateral isolation grooves 6 are formed, e.g. between adjacent columns wholly or mainly by mechanical cutting, this giving a narrower groove and hence higher resolution than an etched groove. Chemical or electrolytic etching may be used for the final portion of grooves otherwise mechanically cut.</p> |
