Abstract

A holding device 1 is adapted to grip and hold a substrate 10 for transport and positioning during fabrication processes. Substrates such as large disks are used in the fabrication of recording media for magnetic and optical data storage. Such disk substrates usually have a circular opening 1 1. The holding device 1 is designed for handling such substrates with minimal physical contact during processing.

A holding device 1 is adapted to grip and hold a substrate 10 for transport and

positioning during fabrication processes. Substrates such as large disks are used in the fabrication of recording media for magnetic and optical data storage. Such disk substrates usually have a circular opening 1 1. The holding device 1 is designed for handling such substrates with minimal physical contact during processing.

Device 1 consists of three sprin~wire legs 2 secured at their upper ends in fixture
3. Legs 2 are spaced apart 120 and are at a lateral angle relative to the central

longitudinal axis of fixture 3.

The bottom extent of each leg 2 is provided with an outwardly extended shoulder 4, A spring loading member 5 is placed between the spring legs 2 so that the legs are forced outwardly to a position where the circular extent of shoulders 4 is

circumferentially larger than the opening 11.

SUBSTRATE HOLDING DEVICE (Cont'd)

In use, device 1 is cradled in the hand so that fixture 3 extends into and along the arch of the hand defined by the thumb, index and middle fingers. By bringing the index and middle fingers toward the thumb, the three spring legs are squeezed inwardly below member 5 so that shoulders 4 can easily fit through opening 11.
