Destruction of a semiconductor element or the like due to electrostatic discharge (hereinafter referred to as “ESD”) is called an electrostatic breakdown. The electrostatic breakdown is one of causes which greatly reduce yield. As a conventional method for avoiding the electrostatic breakdown, there are a method in which discharge due to static electricity is not generated and a method in which damage caused by discharge to the semiconductor element is suppressed even when discharge is generated due to static electricity. As the former method, a method for eliminating generated static electricity by providing an ionizer in semiconductor manufacturing equipment is known. A typical example of the latter method is a method for manufacturing a protection circuit with a semiconductor element, and a high potential generated by discharge can be prevented from being applied to the semiconductor element because of the protection circuit
Hereinafter, embodiment mode and examples of the present invention will be described with reference to the accompanying drawings. The same element is denoted with the same reference numeral and the redundant description is omitted. The present invention can be implemented in various modes. As can be easily understood by a person skilled in the art, the modes and details of the present invention can be changed in various ways without departing from the spirit and scope of the present invention.
Thus, the present invention should not be interpreted as being limited to the following description of the embodiment mode and examples.
The release layer 12 can be formed of metal-or alloy, for example. Metal is tungsten (W), molybdenum (Mo), titanium (Ti), tantalum (Ta), niobium (Nb), nickel (Ni), cobalt (Co), zirconium (Zr), zinc (Zn), ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os), iridium (Ir), or the like. Alloy is alloy of a plurality of metal elements selected from these metal elements such as alloy of tungsten and molybdenum. A metal film and an alloy film of the element can be formed by a sputtering method.
In addition, the thickness of the metal film or alloy film to serve as the release layer 12 may lie within the range of 20 nm to 100 nm.
Next, as shown in FIG. 8, liquid holding means 21 containing the liquid 15 is inserted in a gap generated by peeling. Note that, after the liquid holding means 21 is inserted in the gap, the liquid 15 may be supplied with a chopper or a nozzle, and the liquid holding means 21 may contain the liquid 15. As the liquid holding means 21, one having a function to absorb liquid such as sponge or cloth can be used.
As shown in FIG. 27, an integrated circuit was formed of a semiconductor element such as a TFT or a capacitor over the insulating film 101 In FIG. 27, as a cross-sectional view of the integrated circuit, only a CMOS circuit formed of an n-channel TFT 104 and a p-channel 1141 105 was illustrated. Note that 48 (8 rows×6 columns) integrated circuits which were arranged in matrix were formed over one substrate 100 at the same time.

Next, by using SiH4, H2, N2, NH3 and N2O for process gas, a silicon oxynitride (SiOxNy, x<y) film 507 having a thickness of 100 nm was formed over the amorphous silicon film 506 with the plasma CVD apparatus. By using SiH4 and N2O for process gas, a silicon oxynitride (SiOxNy, x>y) film 508 having a thickness of 600 nm was formed over the silicon oxynitride film 507 with the plasma CVD apparatus. Next, by irradiation of a UV laser beam from the glass substrate 500 and cutting the glass substrate 500 over which the films 501 to 508 were formed, the size of a sample was set as a rectangle of 20 mm×100 mm. FIG. 34 is a plan view of the sample processed into a rectangular shape. Next, in order to form a trigger for peeling, a groove 510 which reached the tungsten film 502 was formed in the sample by UV laser beam irradiation, as shown in FIG. 34. By forming the groove 510, peeling is generated between the silicon oxynitride film 503 and the tungsten film 502. The sample for a peel test was prepared by the above-described method.
