Publication number: 20090121236Abstract: This invention details how a low cost opto coupler can be made on Silicon On Insulator (SOI) using conventional integrated circuit processing methods. Specifically, metal and deposited insulating materials are use to realize a top reflector for directing light generated by a silicon PN junction diode to a silicon PN junction photo diode detector. The light generator or LED can be operated either in the avalanche mode or in the forward mode. Also, side reflectors are described as a means to contain the light to the LED-photo detector pair. Furthermore, a serpentine junction PN silicon LED is described for the avalanche mode of the silicon LED. For the forward mode, two LED structures are described in which hole and electrons combine in lightly doped regions away from heavily doped regions thereby increasing the LED conversion efficiency.Type: ApplicationFiled: November 10, 2008Publication date: May 14, 2009Inventor: Eugene Robert Worley

Patent number: 7524687Abstract: A method for producing an integrated semiconductor component comprising a first semiconductor layer construction for emitting radiation and a second semiconductor layer construction for receiving radiation, wherein a substrate is first provided and a first semiconductor layer sequence containing a radiation-generating region is deposited epitaxially on the substrate. A second semiconductor layer sequence containing a radiation-absorbing region is subsequently deposited epitaxially on the first semiconductor layer sequence. The second semiconductor layer sequence is then patterned in order to uncover a first location and a second location. A first semiconductor layer construction is electrically insulated from a second semiconductor layer construction. Finally, a first contact layer is applied to a free surface of the substrate and a second contact layer is applied at least to the first and second locations for contact-connection.Type: GrantFiled: February 26, 2008Date of Patent: April 28, 2009Assignee: Osram Opto Semiconductors GmbHInventors: Glenn-Yves Plaine, Tony Albrecht, Peter Brick, Marc Philippens
