Key word: Ceramic Wafer Suction Plate
Ceramic wafer suction plate play a key role on the wafer transfer
equipment as automatic wafer unloader and wafer loader machinery .
LPCVD ceramic wafer vaccum suction plate are mainly used in the
solar semiconductor thin film making , like the diffussion wafer
load and unload machine . It used for wafer loading and unloading .
Equipment Name: Automatic Wafer Unloader
Equipment Type: LXP-Ⅲ-B/LXP-Ⅲ-C
Equipment Application: Unload the wafers from 5-lane or 8-lane inline cleaning equipment
to cassettes.
Technical Characteristics
· MES management function.
· With PLC control and the loading process is completed
automatically; Touch-screen operation, which is easy and clear.
· Unload wafers from single lane and adopt buffer unit, which is
easy to operate, the equipment will not stop during cassette swap
and guarantee unloading efficiency.
· Breakage detection and treatment before wafer unload to the
unloader. (Extra charges )
· The wafer cassette’s baseplate can be cycled automatically.

Mingrui Manufacture zirconia Ceramic wafer boat used on automatic
wafer handling system diffusion furnace . As zirconia ceramic with
the charactheristic of wear resistant , high temperature resistant,
ceramic wafer boat is a good choice for wafter carrier .
Integrated wafer loading& unloading, unloading the diffused wafers
from the ceramic wafer boat
to the cassette or loading the textured wafers from the cassette to
the ceramic wafer boat . Available for double back-to-back wafers in one slot in ceramic wafer boat which realize single side diffusion or available for single wafer
in a slot for double side diffusion process. With continuous wafer
loading&unloading can guarantee the continuous production . Or
be used only for wafer loading or unloading is also available.
A
ceramic wafer boat for housing a semiconductor or a solar wafer comprising
at least one wafer support member containing at least one slot
capable of receiving at least a portion of a peripheral edge of a
wafer, wherein in the wafer support member comprises silicon
carbide; and
at least one structural member for conveying the wafer boat into
and out of a processing device connected to the wafer support
member , wherein the structural member is comprised of a ceramic
material that is not silicon carbide.
Technical Characteristics
· With continuous wafer loading& unloading can guarantee the
continuous production. Or be used only for wafer loading or
unloading is also available.
· With perfect detection and alarm system which guarantees the
stable and automatic operation.
· With circulation method of the cassette baseplate which reduce
the labor intensity.
· Modular control program structure, highly repeatable and
readable, which is convenient for function expansion in future and
maintenance;
· With recipe data design which enables the equipment to work with
various kinds of ceramic wafer boat with different accuracy, while running equipment will follow the
boat No. automatically and retrieve the corresponding recipe data
without human intervention.

Industrial Ceramic Intriduction
Aluminium Oxide, Al2O3 is the most widely applied and cost
effective technical ceramic material. It offers a combination of
superior mechanical strength and electrical properties, wear
resistance and corrosion resistance. The maximum working
temperature is up to 1700 °C with relatively high thermal
conductivity. It is also an electrically insulating material with a
high electrical resistivity. The good corrosion resistance makes it
insoluble in water and slightly soluble in strong acid and alkaline
solution.
