| 2 | 生产验证的临时键合与解键合设备及技术(英文)显示文摘化合物半导体材料的应用经历了稳定的增长,尤其是在光电子产业中更为典型。这些材料的应用要求在封装之前需将衬底减薄到100μm以下。由于这种材料的易碎性,需要某种支持方式来通过各种工序对衬底进行处理。半导体行业中建造这种支持最公认的方法是临时固定这种衬底材料到刚性载体基底上。介绍了一种用全自动方式固定和解固定这类衬底的技术。通过采用各种中间基底,包括热和紫外光释放的能够预先准备和薄片状的全自动化干式黏性膜。200mm直径的这种衬底可以以片盒到片盒的方式键合到晶圆平面的这种载体上。本工艺中选用了一种保护性涂层到衬底上。一旦这种衬底固定后,便可以完成随后的减薄、通孔印刷等工序。当这种衬底被减薄和背面处理之后,第二道加工便用于从载体上解键合该衬底,再次以片盒到片盒的方式将其固定到划版的薄膜或类似的载体上。 | H.Kirchberger S.Pargfrieder P.Kettner C.Schaefer | 2005 | 电子工业专用设备2005，34，5： | 1 |
| 4 | Outcome in neonates with necrotizing enterocolitis and patent ductus arteriosus显示文摘Background:There is no agreement of the influence of patent ductus arteriosus(PDA)on outcomes in patients with necrotizing enterocolitis(NEC).In this study,we assessed the infl uence of PDA on NEC outcomes.Methods:A retrospective study of 131 infants with established NEC was performed.Outcomes(death,disease severity,need for surgery,hospitalization duration),as well as multiple clinical parameters were compared between NEC patients with no congenital heart disease(n=102)and those with isolated PDA(n=29).Univariate,multivariate and stepwise logistic regression analyses were performed.Results:Birth weight and gestational age were significantly lower in patients with PDA[median(95%CI):1120 g(1009-1562 g),28.4 wk(27.8-30.5 wk)]than in those without PDA[median(95%CI):1580 g(1593-1905 g),32.4 wk(31.8-33.5 wk);P<0.05].The risk of NEC-attributable fatality was higher in NEC patients with PDA(35%)than in NEC patients without PDA(14%)[univariate odds ratio(OR)=3.3,95%CI:1.8-8.6,P<0.05;multivariate OR=2.4,95%CI:0.82-2.39,P=0.111].Significant independent predictors for nonsurvival within the entire cohort were advanced disease severity stage III(OR=27.9,95%CI:7.4-105,P<0.001)and birth weight below 1100 g(OR=5.7,95%CI:1.7-19.4,P<0.01).Conclusions:In patients with NEC,the presence of PDA is associated with an increased risk of death.However,when important differences between the two study groups are controlled,only birth weight and disease severity may independently predict mortality. | Ulf Kessler Franzisca Schulte Dietmar Cholewa Mathias Nelle Stephan C.Schaefer Peter M.Klimek Steffen Berger | 2016 | World Journal of Pediatrics2016，12，1： | 0 |
