The present invention relates to an ultraviolet detector and manufacture method thereof, in which a buffer layer is formed on a baseplate and a P-type GaN layer is formed on the baseplate by using epitaxial method. By availing ion-distribution-and-vegetation technology, a first N-type GaN layer is vegetated and invested in the P-type GaN layer by distributing and vegetating Si.sup.+ ions in that layer, and a second N-type GaN layer having a thicker ion concentration is invested in the N-type GaN layer.

专利简介本发明系关於一种紫外光检测器及制程方法，其主要系在一基板上形成一缓冲层，利用磊晶法在缓冲层上形成一P型氮化镓系层，并接著以离子布植技术将Si+离子适当地布植於该P型氮化镓系层中，形成一N型氮化镓系层及包覆在此N型氮化镓系层中且布植浓度更高的另一N型氮化镓系层，最后在该P型氮化镓系层及第二N型氮化镓系层上分别镀上一环状金属层及另一金属层，以作为欧姆接触层。

The method of electroless nickel plating was used in this study, let Ni-P particle is suspended form the plating solution, therethrough spontaneous reaction use the alloy is clodding full of the Glass Fiber Woven Cloth, attach the Glass Fiber Woven Cloth have like alloy particle good conductivity, Improved the electric properties of this fibers and help improved high electromagnetic shielding, with Theromoset Resin mixture the conductivity filler graphite, composite with High Electromagnetic Shielding Composites.

摘要本研究使用无电极镀镍之方法，将粒子悬浮在电镀液中，籍由氧化还原反应使玻璃纤维不织布得到完整的包覆金属层，并赋予玻璃纤维不织布具有纯金属粒子一般优异的导电率，藉此提高纤维之导电性并且有助于增加遮蔽电磁波的能力与效果，再与热固性树脂并混入导电性填充材石墨粉墨，复合成具电磁波遮蔽之复合材料。
