## Abstract

A high-strength transportation frame for carrying wafer boats between processing stations in a semiconductor fabrication facility includes a pair of transporting rods each having a corresponding grip portion, a number of fixing elements, and a pair of connecting rods. The connecting rods extend parallel to each other and are connected to each of the pair of transporting rods at remote ends thereof, the connections being secured by the fixing elements.

## Claims

### Claim 1

A transport supporting frame for carrying a wafer boat, comprising:
a pair of essentially parallel transporting rods, each rod being composed of first and second contiguous, longitudinally extending regions, each first region having a respective grip surrounding a portion thereof;
a pair of connecting rods which extend parallel to each other and are connected at ends thereof to the respective first regions of the pair of transporting rods, with each respective grip being disposed between respective ends of the pair of connecting rods; and
a pair of first and second support rods and respective sleeves, connected to the respective second regions of said transporting rods, the second regions being free of a direct connection together so that a wafer boat may be received and carried by said support rods and sleeves.

### Claim 2 (depends on 1)

The transport supporting frame of claim 1, wherein the sleeves comprise a polyimide resin.

### Claim 3 (depends on 1)

The transport supporting frame of claim 1, wherein each respective connecting rod comprises:
an inner rod and an outer hollow rod, the inner rod adjustably fitting inside the outer hollow rod, and
screws which are disposed to extend through the outer hollow rod and secure the inner rod within the outer hollow rod.

### Claim 4 (depends on 1)

The transport supporting frame of claim 1, wherein said transporting rods each comprise an inner and an outer member, the inner member being adjustably inserted into the outer member, and securing means for securing the respective inner member to the respective outer member, wherein the length of the respective transporting rods is adjustable by positioning the respective inner member with respect to the respective outer member.

### Claim 5 (depends on 1)

The transport supporting frame of claim 1, wherein a first one of said pair of connecting rods is connected to the transporting rods at first ends of the transporting rods, and wherein a second one of said pair of connecting rods is connected to the transporting rods at mid regions of the transporting rods.

### Claim 6 (depends on 1)

The transport supporting frame of claim 1, further comprising a plurality of fixing means for securing the connection of the transporting rods and connecting rods.

### Claim 7 (depends on 6)

The transport supporting frame of claim 6, wherein the plurality of fixing means comprise screws.
