Patent EP-0350816-A3 (EP)
IPC: H01L29/861
Filed: 1989-07-08
Abstract: Schnelle Leistungsdiode und Verfahren zu ihrer 
Herstellung.  
     Das Recovery-Verhalten schneller Leistungsdioden 
mit psn-Struktur ist im wesentlichen durch Dotierung 
und Bemessung der hochohmigen Mittelzone bestimmt. 
Solche Dioden erfüllen jedoch nicht alle Anforderungen 
an einen Betrieb in Verbindung mit schaltbaren 
Halbleiterbauelementen.  
Die schnelle Diode nach der Erfindung weist durch 
veränderte Ausbildung der p⁺-Emitterzone ein optimiertes 
Recovery-Verhalten auf und ist auch unter erhöhten 
Anforderungen in unterschiedlichen Schaltungen der 
Leistungselektronik als Freilaufdiode anwendbar. Das 
neue Verfahren ermöglicht mit bekannten Schritten in 
einfacher Weise das Herstellen einer psn-Struktur mit 
gewünschtem Recovery-Verhalten.  
     Bei der neuen Diode ist die p⁺-Emitterzone erheblich 
dünner ausgebildet, und ihre Dotierungskonzentration 
beträgt 10¹⁷ bis 5x10¹⁸ Atome/cm⁻³, 10³ bis 10⁴ Atome/cm⁻³ 
weniger als die der n⁺-leitenden Außenzone. Letztere ist 
noch mit einer n⁺⁺-leitenden Oberflächenzone versehen. 
Verfahrensgemäß werden zunächst an der Mittelzone die 
n⁺-leitende Zone und die p⁺-Emitterzone erzeugt, danach 
wird die n⁺⁺-Oberflächenzone ausgebildet, und 
Schwermetallatome werden p-emitterseitig eingebracht.

Title: Optical modulator
IPC: G02F1/017
Filed: 1989-08-02
Abstract: A method of modulating light (28) incident to a 
semiconductor body (10) comprising the steps of: 
coupling the incident light (28) to the surface 
plasmon polariton mode (44) at an interface (21) of 
the semiconductor body (10); and selectively altering 
the absorption of the incident light (28) by the
