The present invention refers to hermetic limit and maximum limit to determine whether method relates to wafer transfer using the same, by writing their, peripheral environmentally sensitive electronic component a precision and are reactive with an organic acid material wafers to a safely such that one transfer unit can transfer: a hermetic limit and maximum limit to determine whether said wafer using the same a substantially relates to method.

[2]

Generally, a semiconductor chip consisting of a monocrystalline substrate thin beamlike silicon wafer (wafer) fab are patterned by using a photolithography plurality circuit pattern on said patterned semiconductor chip (FAB) process and performance of electrical a tester for checking the (EDS) process is performed to is bath number.

[3]

Wherein, said semiconductor chip substantially as of electronic be precisely, alien substances around and to temperature and humidity of the insertion part and the holder by making the processes reacted highly sensitive, fab said a site (FAB) process said inspection (EDS) process is performed each the locations are external and structural completely screened necessarily is connected to the semiconductor layer..

[4]

In addition, said fab (FAB) process and said inspection (EDS) step for vertically arranged wafer said wafer is said rails a rack is (FOUP, Front Open Unified Pod) or non (FOSB, Front Open Shipping Box) mechanism such as are used KIPO & general rule, .

[5]

The, said wafers are mechanism such as said state is housed in said fab (FAB) process is performed in a place that a process said inspection (EDS) (FAB) of a delivery point or an fab said a process is transported to a another location by supplying and carrying away air, fab (FAB) of said process and said inspection (EDS) process can be of effectively performing.

[6]

In this case, is provided to transfer the building the same place has an external is disposed said exposed to an environment may transfer a proper system for a mechanism but a non - intrusive, is provided to transfer the relatively place has an other, and the distance between the is disposed building if the key mechanism said opening is formed with magnetic force semiconductor wafers are said vinyl a mechanism, for example by transfer after packaging folly closed is connected to the semiconductor layer. the need.

[7]

For luncheon and to take a, a worker gives an number and the packaging of said mechanism that triggers since should go further process, the efficiency of an falling door is connected to the semiconductor layer. point number.
