Title: Method of fabrication of thin film transistor
Inventor: NAKAJIMA MITSUO
IPC: H01L29/786
Filed: 1993-09-22
Abstract: PURPOSE:To form a microcrystal silicon film not including an amorphous layer on a gate insulating layer interface at a speed high enough to form a device by specifying a hydrogen concentration ratio upon formation of a silicon layer in the vicinity of the gate insulating layer interface and after the foregoing formation of the silicon layer. CONSTITUTION:A metal film such as Ta or an MoTa alloy is deposited on a transparent insulating substrate 1, and is patterned by plasma etching using CF4 and O2 for example as reaction gases to form an electrode 2. Then, a gate insulating film 3, a first microcrystal silicon film 4a as an active layer, and a second microcrystal silicon film 4b are deposited in order to form a microcrystal silicon layer 4. The ratio of hydrogen concentration of stock gas upon the first microcrystal silicon film 4a being formed to the hydrogen concentration of the stock gas upon the first microcrystal silicon film 4a being formed is 1. Thus, the microcrystal silicon layer can be formed from the neighourhood of the gate insulating film interface to ensure a TFT corresponding to p-Si in a low temperature process.

Abstract: PROBLEM TO BE SOLVED: To completely solving a so-called air bubble problem where air is trapped by a method wherein a developing solution is discharged out from a supply source as being bundled as if it is discharged out from a hollow nozzle and made to spread concentrically over a wafer from its center to periphery. SOLUTION: One thousand to thirty-two thousand of hollow fiber tubes which are 0.1 to 0.5 mm in inner diameter are bundled and attached to the tip of a hollow tube. A developing solution discharged out form the fiber tubes becomes hemispherical and get gradually expanding to become spheres, where flows of developing solution discharged out from the adjacent fiber tubes come into contact with each other to turn into spheres of an integral structure. A developing solution drops down on a wafer W increasing in volume, and flows of developing solution are discharged out from fiber tubes as being bundled as if they are discharged out from a single hollow nozzle and made to spread concentrically over the wafer W from its center to periphery. Thereafter, the surface of the wafer W is uniformly coated with a thin film of developing solution.
