Logosol Prealigner - The LPA series Logosol Prealigner are an innovative, high-precision, class 1 clean room solution with integrated scan electronics.
These Logosol Prealigner make it possible to align objects from 45 mm to 480 mm, regardless of their degree of transparency. They centre wafers, masks and other substrates, detect notches, flats or other marks and align the object exactly and independently. The Logosol Prealigner are developed and produced by Logosol Inc. USA. isel Germany AG is a authorised distributor for Europe.
Single-axis Logosol Prealigner
Single-axis Logosol Prealigner (embedded) only operate in conjunction with an isel wafer handler and are integrated into the system as an additional axis. Given that this prealigner only has a single axis (rotation), the first step is to determine the adjustment values for centring the wafer and the notch / flat is aligned. In the second step the robot adjust the eccentric offset when picking up the wafer with adapted station coordinates. A vacuum between the end effector and the prealigner ensures that the wafer is secured at all times and is in contact at the rear. This prealigner is a cost-effective solution for standard wafers of 45 mm Ø - 470 mm Ø.
Triple-axis Logosol Prealigner
Triple-axis Logosol Prealigner (standalone) are devices which operate independently and align square or rectangular substrates of 45 mm Ø - 480 mm Ø with high precision, regardless of their transparency. The alignment of different objects of various sizes is implemented without mechanical adjustment of the prealigner. The prealigner has a chuck load and a pin load mode and and optional high precision mode, dual layer function (stacked wafer) or external sensors for detecting edge markings. A vacuum between on the chuck and pins ensures that the wafer is secured at all times and is in contact at the rear. A large number of different contact materials for chucks and pins and friction chucks (without vacuum) are optionally available. Given that triple-axis Logosol Prealigner work self-sufficiently and also have an RS232 and an Ethernet interface, the devices can be integrated into any robot system.
"Edge handling" Logosol Prealigner
Edge handling Logosol Prealigner are devices which operate self-sufficiently with passive contact in the edge area of the wafer. This guarantees the highest level of purity and freedom from stress when handling wafer of 75 mm Ø - 300 mm Ø. A high precision variant is also optionally available.
