초록 ▼

Thin film transistors in which the active layer is an ordered film of a pthalocyanine coordination compound with a field-effect mobility greater than 10.sup.-3 cm.sup.2 /Vs and a conductivity in the range of about 10.sup.-9 S/cm to about 10.sup.-7 S/cm at 20.degree. C. are disclosed. Examples of suitable pthalocyanines include copper pthalocyanine, zinc pthalocyanine, hydrogen pthalocyanine, and tin pthalocyanine. Thin film devices made of these materials have an on/off ratio of at least about 10.sup.4. It is advantageous if the device is fabricated using a process in which the substrate is heated to a temperature in the range of about 30.degree. C. to about 200.degree. C. when the film is formed thereon.

대표청구항 ▼

[ What is claimed is:] [1.] A thin film transistor comprising:a substrate with a layer of a highly ordered phthalocyanine coordination compound formed thereon, and contacts for applying current through the layer of the phthalocyanine coordination compound wherein the phthalocyanine coordination compound has a field-effect mobility greater than 10.sup.-3 cm.sup.2 /Vs and a conductivity in the range of about 10.sup.-9 S/cm to about 10.sup.-7 S/cm at 20.degree. C. and wherein the thin film transistor has an on/off ratio of the source drain current that is at least 10.sup.4.
