The invention belongs to the technical field of organic electronic devices, and particularly relates to a method for preparing an organic field effect transistor dielectric layer by using a plasma crosslinking technology. Firstly a gate or a gate and an insulating layer are prepared on a substrate. And then monomer which can be polymerized is activated by the plasma through a plasma enhanced chemical vapor deposition (PECVD) method, and a compact, ultrathin and crosslinking organic matter dielectric layer grows on the gate or the dielectric layer. A semiconductor layer is then prepared on a thin film. Finally a source electrode and a drain electrode are made. The PECVD method is used to achieve mutual crosslinking of organic materials and further the compact and ultrathin dielectric layer with high insulation is prepared. The method is simple and convenient. Flexible electronic devices made of the full organic materials can be realized, and the problem that inorganic materials can not bend is overcome. The thin film with high crosslinking has good insulating property. The preparation of the ultrathin dielectric layer required by the flexible electronic devices can be achieved. Meanwhile the organic materials are not dissolved in general organic solvents, and a full solution method for preparing an organic field effect transistor can be realized.
