Latest Patents

Oka's latest patents include an "Apparatus and method for detecting and conveying substrates in cassette." This innovative substrate detecting apparatus features a light sensor unit with a light-emission element and a light-receiving element positioned to face each other across the cassette. It also incorporates a vertical driving device that allows for relative vertical movement between the light sensor unit and the cassette. Additionally, a substrate position detector is included to determine the vertical positional range of each substrate based on the output signal generated by the light sensor unit during movement.

Another significant patent is the "Interface apparatus for transporting substrates between substrate processing apparatus." This interface apparatus is designed to transfer substrates between various processing apparatuses that provide treatments for the substrates. It includes a transfer mechanism that receives substrates from an upstream processing apparatus and delivers them to a downstream processing apparatus. In the event of a malfunction in the downstream apparatus, the substrates are deposited in a storage by a depositing and fetching mechanism until the issue is resolved.
