二维光子晶体的软平板印刷技术制作研究

分析了软平板印刷技术制作二维光子晶体的特点和方法.利用绝缘PDMS模板,采用软平板印刷技术制造了三角晶系结构的二维聚合物光子晶体,采用同样的技术成功制成尺寸为150～500nm,纵横比达1.25的高密度二维光子晶体.与其他制作技术相比,平板印刷技术具有大尺寸和易于制作的优点.结果表明,制作获得的微结构有很高的保真度.

聚氨酯分子印章的制备和表征

Polyurethane based on polypropylene glycol(PPG) and TDI using 3,3\|dichloride\|4,4\|methylenedianiline(MOCA) as the crosslinker is presented for the first time to fabricate molecular stamps(PU stamps) for the synthesis of DNA microarray with contact procedure. The predictability of the process is achieved by utilizing commercially available starting materials. SEM analysis of the morphology of PU stamps and photoresist motherboard showed that PU elastomer could replicate subtly the motherboards patterns with a high fidelity. It was proved from the contact angle measurement that PU stamps surface has a good affinity with acetonitrile, which guarantee the well\|distribution of DNA monomers on patterned stamps. Laser confocal fluorescence microscopy images of oligonucleotide arrays confirm that polyurethane is an excellent material for molecular stamps.

Soft Imprint Lithography for Pixel Array Manufacturing in OLED

Introduction During the last two decades,organic light-emitting diodes (OLED) have attracted considerable interest owing to their promising applications by replacing cathode ray tubes (CRTs) or liquid crystal displays (LCDs).

Moore神话的延续者——神奇的LADI技术

1965年,戈登·摩尔（InteI公司的创始人之一）注意到他手下的工程师们（其中的大多数成为了InteI公司的第一批雇员)能够取得每一年使集成电路上的晶体管数量翻一倍的成绩。根据他对行业和制造工艺的了解，他提出了一个构想——这种增长速度将在未来的10年左右继续维持下去．而晶体管尺寸的缩小和集成度的增加势必会让集成电路变得更加便宜，功能更强大，而且模块化程度将更高。
