Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To obtain mechanical type parking equipment having a tilt detector which can monitor constantly the tilt of an elevating stage provided on a running carriage and moving up and down. SOLUTION: It is determined whether running acceleration α in the horizontal direction of a running carriage 32 supporting an elevating stage 35 elevatably is 0 or not. In the case when the running acceleration α of the running carriage 32 is determined as 0, angle data θ from a tilt sensor 35a provided on the elevating stage 35 is adopted as a tilt angle θ' of the elevating stage 35 as it is. In the case when the running acceleration α of the running carriage 32 is determined as not 0, on the other hand, an error amount Δθ given to an output of the tilt sensor by the running acceleration α of the running carriage 32 is calculated on the basis of acceleration data from an acceleration sensor 32a provided on the running carriage 32. Then, an actual tilt angle θ' is calculated as a difference between the error amount Δθ calculated in this way and the angle data θ from the tilt sensor 35a. In the case when the angle θ' is judged to be larger than a danger determining angle θs , the situation is determined as dangerous and equipment is brought to an emergency stop.

Title: Centrifugal drier for semiconductor
Inventor: KANEKO NAOJI
IPC: H01L21/304
Filed: 1986-10-02
Abstract: PURPOSE:To dry the surface uniformly by a method here a means to supply a wafer with water is installed at a side wall of a centrifugal drier so that the wafer cannot be dried up naturally until it is dried by centrifugal effect. CONSTITUTION:After a wafer 10 has been treated by a wet method, it is stored in a cassette 4, which is then stored in a basket 3. Pure water is ejected from a nozzle 7 located at a position corresponding to the cassette 4, and the surface of the wafer 10 is sprinkled with the water. Pure water 11 is retained on the surface thanks to the surface tension at the wafer. If all the cassettes are stored in the same manner, a centrifugal drier starts operating and the nozzle stops the operation of water sprinkling. As a result, the water 10 is dried by centrifugal effect while a rotary table 2 is rotated at high speed. Through this constitution, the wafer can be dried uniformly, and it is possible to form a high-quality and stable semiconductor device.
