Patent number: 10050187Abstract: The light-emitting device includes a base plate, a bonding metal layer, a conductive oxide layer, an epitaxial layer, an insulation layer, a first ohmic contact layer, a second ohmic contact layer, a third ohmic contact layer, and a conductor line. The light-emitting device of the present invention uses the process of providing a conductor line to connect an ohmic contact layer, instead of wire bonding, so that a package process required by wire bonding can be eliminated to thereby reduce the size of the light-emitting device. Further, the light-emitting device, after the formation of the conductor line on the ohmic contact layer, allows for performance of a step of directly bonding to a circuit board so as to reduce the package size and simplify equipment necessary for the package process to thereby further lower down fabrication costs, achieving the effects of simplification of operation and fast fabrication.Type: GrantFiled: October 3, 2017Date of Patent: August 14, 2018Assignee: Tyntek CorporationInventors: Yi-Hung Chen, Yung-Jung Liang

Patent number: 7525246Abstract: An alternating current light-emitting device includes a substrate, an alternating current microdie light-emitting module, and a conductive structure. The alternating current microdie light-emitting module is formed on the substrate and has at least two microdies and a concave portion disposed between the two microdies. Each of the microdies has at least one active layer. The conductive structure electrically connects the microdies and thereby enables the active layers of the microdies to take turns to emit light during positive and negative half cycles of alternating current. The conductive structure is formed in the concave portion and covers an insulator. The present invention prevents undue open circuits but enhances yield.Type: GrantFiled: November 8, 2006Date of Patent: April 28, 2009Assignees: Industrial Technology Research Institute, Tyntek CorporationInventors: Hsi-Hsuan Yen, Wen-Yung Yeh, Chih-Shu Huang, Kuo Jui Huang, Ming-Te Lin

Patent number: 6720664Abstract: A submount holder for flip chip packaging of light emitting diode (LED) includes a substrate on which a body is formed. The submount body defines a cavity sized and shaped to snugly receive an LED die therein. The cavity precisely retains the die in position and prevents the die from arbitrary movement during a packaging and wiring process. First and second connection sections are formed on opposite sides of the cavity and respectively connected to the cavity by a channel. A conductively layer is formed on the substrate in the cavity, the first and second connection sections and the channels connecting the connection sections and the cavity. A groove is defined in the body and extends through the cavity with the connection sections located on opposite sides of the groove. The conductive layer is divided by the groove into separated and isolated portions.Type: GrantFiled: April 22, 2003Date of Patent: April 13, 2004Assignee: Tyntek CorporationInventors: Chi-Jen Teng, Wan-Fang Shih, Zhi-Ping He, Cheng-Wei Ko
