据加州大学伯克利分校的化学家说,受光照射后由电绝缘体变成导体的新型聚合物的实现可能为集成电路制造提供一种廉价的方法。该校已发展一种一步法制作印刷电路的处理工艺。Novak 和其同事已合成一种称为芳化聚亚苯基硫化物(APPS)的光致抗蚀聚合物,发现当APPS 薄膜受光照射时,即变成永久性导体,未曝光区域仍为绝缘体。APPS 的这种独特性质可使永久不磨灭的高分辨率导电电路直接印制在薄膜上。已存在许多导电聚合物,但由于 APPS 制作容易和廉
According to chemists at the University of California, Berkeley, implementing new polymers that change from electrical insulators to conductors after light exposure may provide an inexpensive way to make integrated circuits. The school has developed a one-step process for the production of printed circuit processing. Novak and coworkers have synthesized a photo-resist polymer known as arylated polyphenylene sulfide (APPS) and found that the APPS film becomes a permanent conductor when exposed to light and the unexposed area remains an insulator . This unique property of APPS enables permanently printed high resolution conductive circuits to be printed directly on the film. Many conductive polymers already exist, but because APPS is easy and inexpensive to make
