Research and Development of Monolithic Optoelectronic Integrated Receiver by BCD Technology

光纤通信的飞速发展促使其关键器件—光发射及光接收芯片的技术革新。光接收芯片单片光电集成化就是技术革新中的重要趋势。与传统混合集成的光接收芯片相比，单片光电集成具有低成本、高性能的明显优点。 在标准CMOS工艺下，因为杂质掺杂浓度较大，PN结结深较浅。而硅材料在850nm的光照下吸收深度较深，这使处于衬底深处的光生载流子由于缺少电场作用必须经过较大的延迟才能到达PN结的空间电荷区边缘，限制探测器的响应带宽。商业化的BCD工艺比标准CMOS工艺多了一个N型埋层，N型外延层中杂质掺杂浓度较低，故而本论文充分利用这些特点来构建P+/N型外延层/N阱埋层（类似PIN）结构的光电探测器，可以大幅度减小光...With the rapid development of optical communication technology, optical transmitters and receivers are renewed every second, which has attracted great attention in study of monolithic optical receiver chip. Compared with mixed integration, the monolithic integration has advantages of low cost and high performance. In standard CMOS technology, the length of PN junction is too shllow for the photo...学位：工学硕士院系专业：物理与机电工程学院机电工程系_机械电子工程学号：1992007115115

ブドウ \u27シャインマスカット\u27 におけるチャノキイロアザミウマの発生消長と光反射シートマルチを利用した減農薬防除の検討

Occurrence of yellow tea thrips (YTT), Scirtothrips dorsalis and insecticide spraying reduced program using reflective sheet (RS) mulching were investigated in hedgerow grapevine cultivar \u27Shine Muscat\u27 (Vitis labruscana Bailey × V. vinifera L.). 1. First catches of YTT adults on yellow sticky traps in grape orchards were observed in mid- to late May or mid-June. Trap catches of YTT tended to be decreased by RS mulching. First infestation of YTT adults on grape shoots was observed in late May or mid-June. Infestation of YTT adults on shoots tended to be delayed by about 2 to 4 weeks by RS mulching, and the number of YTT infesting grapevine shoots tended to decrease with RS mulching. 2. The overwintering generation of YTT adults was collected from Distylium racemosum, Hydrangea macrophylla, Viburnum odoratissimum, and two species of weeds, Lamium amplexicaule and Vicia sativa subsp. nigra. First-generation of YTT adults were collected from Podocarpus macrophyllus and Camellia sinensis. It is likely that first-and second-generation of YTT adults grown on these host plants flew to grapevines. 3. Estimated immigration peaks of the first-, second- and third generation of YTT adults coincided with the peaks of trap catches of the first- and second-generations and the period of the number of YTT adults increasing on grapevine shoots in July, respectively. 4. Fruit damage in grapevines not sprayed with insecticide and without mulching (unsprayed), those receiving conventional insecticide spraying without mulching (conventional), and those with reduced insecticide spraying with RS mulching (mulching) were compared. Infestation of YTT adults on unsprayed grapevine shoots was observed in late May and late June, and fruit damage was observed in this block. Infestation of YTT adults on grapevine shoots in the conventional and mulching treatments was not observed by the bagging day, and no fruit damage was observed in these blocks. 5. Insecticide spraying timed during immigration of the first-generation of YTT adults was considered to be unnecessary if RS mulching was used. However, because second-generation YTT adults were observed on shoot tips of grapevine with RS mulching, insecticide spraying timed during adult immigration in this generation was considered to be necessary
