Abstract:
A monocrystal and polycrystal texturing device includes a device body, various stations arranged in the device body, a transmission device and a control system. The various stations are respectively a dipping acid texturing station, a spray washing station, a drying station, a spray alkali texturing station, a spray washing station, a dipping acid treatment station, a spray washing station, an acid treatment station, a spray washing station and a drying station arranged in sequence. The transmission device is for transmitting a silicon wafer to each station in sequence. The spray alkali texturing station is also connected with a heating device. The control system controls the working status of each station and the heating device. The technology of the present invention has the advantages of stable operation, high efficiency and reliability, and can conduct seamless switching among polycrystal acid texturing, monocrystal alkali texturing, monocrystal acid texturing, and monocrystal alkali texturing.

Claim (Index 1):
A monocrystal and polycrystal texturing device, comprising a device body, various stations arranged in the device body, a transmission device and a control system, wherein the various stations are respectively a dipping acid texturing station, a spray washing station, a drying station, a spray alkali texturing station, a spray washing station, a dipping acid treatment station, a spray washing station, an acid treatment station, a spray washing station and a drying station arranged in sequence, the transmission device is for transmitting a silicon wafer to each station in sequence, the control system controls the operating on-off status of each station, and when the device conducts monocrystal texturing, the control system only opens the stations required by monocrystal texturing; and when the device conducts polycrystal texturing, the control system only opens the stations required by polycrystal texturing;\n the dipping acid texturing station comprises an acid texturing slot, multiple pairs of separation plates separating the acid texturing slot into multiple working liquid chambers, an acid texturing pump for pumping the acid texturing liquid into the working liquid chambers, and an acid texturing sub-slot for collecting the acid texturing liquid in the acid texturing slot; each pair of separation plates are spaced to form a cushion chamber for overflow cycle, and the bottom of the cushion chamber is provided with an output port connected with the acid texturing sub-slot; the spray washing station comprises: a spray washing slot, a spray header arranged above the spray washing slot, and a water pump for pumping the water washing liquid into the spray header; the drying station comprises a hot-air blower for providing an air source and a filter for filtering the air source; the spray alkali texturing station comprises an alkali texturing slot, a spray alkali liquid box arranged above the alkali texturing slot, an alkali texturing pump for pumping the alkali texturing liquid into the spray alkali liquid box, and an alkali texturing sub-slot for collecting the alkali texturing liquid in the alkali texturing slot; the dipping alkali treatment station comprises an alkali treatment slot, multiple pairs of separation plates separating the alkali treatment slot into multiple working liquid chambers, an alkali treatment pump for pumping the alkali treatment liquid into the working liquid chambers, and an alkali treatment sub-slot for collecting the alkali treatment liquid in the alkali treatment slot, each pair of separation plates are spaced to form a cushion chamber for overflow cycle, and the bottom of the cushion chamber is provided with an output port connected with the alkali treatment sub-slot; and the acid texturing pump, the water pump, the hot-air blower, the alkali texturing pump and the alkali treatment pump are respectively connected with the control system, and the control system controls the on-off status thereof.
