Title (EN) LIGHT EMITTING DEVICE CONTACT LAYERS HAVING SUBSTANTIALLY EQUAL SPREADING RESISTANCE AND METHOD OF MANUFACTURE
(FR) COUCHES DE CONTACT A RESISTANCE INTRINSEQUE SENSIBLEMENT EGALE POUR DISPOSITIF ELECTROLUMINESCENT ET PROCEDE DE FABRICATION
Abstract:
(EN) A light emitting device and method of fabricating a light emitting device. The device contains a light emitting junction, such as a pn junction. Contacts (11, 15) to the junction are designed to have substantially the same spreading resistance to produce a substantially uniform voltage across the light emitting junction. This will produce substantially light emission by the junction. The contacts can include contact layers (11, 15) whose spreading resistances are substantially matched by controlling the doping, thickness and/or composition of the layers.
(FR) La présente invention concerne un dispositif électroluminescent et un procédé de fabrication de ce dispositif. Le dispositif comprend une jonction électroluminescente, notamment une jonction PN. Des contacts (11, 15) disposés sur la jonction sont conçus de manière à avoir sensiblement la même résistance intrinsèque, et produire une tension sensiblement uniforme à travers la jonction électroluminescente, lui permettant ainsi d'émettre une lumière sensiblement uniforme. Ces contacts peuvent comprendre des couches de contact (11, 15) dont les résistances intrinsèques sont sensiblement adaptées par la régulation du dopage, de l'épaisseur et/ou de la composition des couches.
