Patent

CA 2497344

A light-emitting device comprises a substrate (205) that has a contact plug (240) extending therethrough between first and second opposing surfaces. An active region is on the first surface, a first electrical contact is on the active region, and a second electrical contact is adjacent to the second surface of the substrate. The contact plug couples the second electrical contact to the active region. Such a configuration may allow electrical contacts to be on opposing sides of a chip, which may increase the number of devices that may be formed on a wafer.

Composant électroluminescent comprenant un substrat (205) traversé par une prise de contact (240) entre une première et une deuxième surfaces opposées . Une zone active est située sur la première surface, un premier contact électrique est situé sur la zone active et un deuxième contact électrique est contigu à la deuxième surface du substrat. Cette prise de contact couple le deuxième contact électrique à la zone active. Cette configuration peut permettre aux contacts électriques d'être placés sur les côtés opposés d'une puce, ce qui peut augmenter le nombre de composants pouvant être créés sur une tranche.
