THIN FILM DEVICE HAVING COATING FILM, LIQUID CRYSTAL PANEL, ELECTRONIC APPARATUS AND METHOD OF MANUFACTURING THE THIN FILM DEVICE

摘要

Liquid is applied and subjected to a heat treatment to form one thin film among an insulating thin film, a silicon thin film and a conductive thin film constituting a TFT. A substrate is spin-coated with the liquid which contains a thin film component and is supplied from the coating liquid storing part (105) of a spin-coater (102). The substrate to which the coating liquid is applied is subjected to a heat treatment by a heat treatment unit (103) to form a coating film on the substrate. If, further, the coating film is subjected to laser annealing, etc., one of the film qualities, crystallinity, denseness and adhesion is improved. If the coating liquid or resist is applied by an ink-jet method, the utilization efficiency of coating liquid can be improved and, further, a patterned coating film can be formed. A thin film device which is low in cost and has a high throughput can be obtained. By manufacturing TFTs with a manufacturing apparatus having the high utilization efficiency of the coating liquid, the initial investment and the cost of a liquid crystal display are significantly reduced.
