[0038] The semi-floating gate transistor can be the semi-floating gate transistor structure described in the literature (Wang P, Lin X, Liu L, et al. A semi-floating gate transistor for low-voltage ultrafast memory and sensing operation. [J]. Science (New York, N.Y.), 2013, 341(6146): 640-643.) or the semi-floating gate transistor structure described in Chinese patent CN201410201614.6, which includes a semiconductor substrate (P type), an N+ type source formed by ion implantation in the semiconductor substrate, a large N type drain formed by two-step ion implantation, a bottom dielectric, a semi-floating gate, a top dielectric, a control gate, and a slot formed in the middle of the bottom dielectric by etching, so that the semi-floating gate directly contacts the drain. Compared with the traditional floating gate transistor, the semi-floating gate transistor uses the quantum tunneling effect of the TFET in the silicon body and replaces the traditional silicon oxide data erasing window with a PN junction diode.
[0039] The composite medium gate photosensitive detector may be, for example, the photosensitive composite medium gate MOSFET detector described in Chinese patent CN200910024504.6. The photosensitive detector comprises: a semiconductor substrate (P type); a bottom layer insulating medium, a photoelectron storage layer, a top layer insulating medium and a control gate arranged in sequence on the top of the semiconductor substrate; and N type source and drain formed by ion implantation and doping in the semiconductor substrate (close to both sides of the stacked medium). By applying a gate voltage greater than the threshold voltage to the control gate, the voltage difference between the source and the drain is 0, and a large voltage difference is set between the P type substrate and the source to generate a relatively wide depletion region on the substrate. The cold electrons generated in the substrate are accelerated by the electric field in the depletion region to obtain energy, and when the energy is greater than the potential barrier between the substrate and the bottom layer medium, the electrons directly cross the potential barrier into the bottom layer medium and move at a high speed in the direction of the gate under the action of the electric field in the bottom layer medium, thereby generating gate injection current.
[0040] The double-device photosensitive detection unit based on the composite medium gate may be, for example, the double-device photosensitive detection unit based on the composite medium gate described in Chinese patent CN201610592997.3. The photosensitive detection unit comprises a composite medium gate MOS-C part with a photosensitive function and a composite medium gate MOSFET part with an information reading function, and the two parts are formed on the top of the same P type semiconductor substrate; the composite medium gate MOS-C part comprises a charge coupling layer, a first top layer medium layer and a first control gate arranged in sequence on the top of the P type semiconductor substrate, wherein an N type injection layer is arranged in the P type semiconductor substrate and below the charge coupling layer; the composite medium gate MOSFET part comprises a bottom layer medium layer, the charge coupling layer, a second top layer medium layer and a second control gate arranged in sequence on the top of the P type semiconductor substrate, wherein an N type source region and an N type drain region are arranged in the P type semiconductor substrate and close to one side of the bottom layer medium layer, and a threshold adjustment injection region is arranged in the P type semiconductor substrate and below the bottom layer medium layer; in the P type semiconductor substrate, the N type injection layer is separated from the N type source region and the N type drain region by a shallow trench isolation region and a P+ type injection region. When working: the control gate is applied with 0 bias, and the substrate is applied with a negative bias pulse to form a depletion layer in the substrate. When photons are absorbed by the semiconductor when light is incident into the depletion layer, photoelectrons are generated, which are driven by the gate voltage to move to the substrate and gate oxide interface, where they are accumulated, so that the threshold voltage of the reading transistor changes, thereby representing the number of photoelectrons, and converting the optical signal into a quantifiable electrical signal.
[0041] The split-gate MOSFET imaging detector can be the split-gate MOSFET imaging detector described in Chinese patent CN201210349285.0. The structure of the imaging detector comprises: two layers of insulating medium materials and a control gate are respectively arranged on the top of a substrate P-type semiconductor material, and a photoelectron storage layer is arranged between the two layers of insulating medium materials. The control gate surface or the substrate layer has at least one window which is transparent or semi-transparent to light in the wavelength range detected by the detector. Two sides of the floating gate MOSFET on the substrate P-type semiconductor material are provided with selection gates, and an insulating medium layer is arranged between the selection gates and the substrate, and the insulating medium layer has the same material and thickness as the bottom insulating medium layer. An N-type semiconductor region is arranged on the peripheral P-type substrate of the substrate controlled by the two selection gates, thereby forming a source and a drain of the split-gate MOSFET. The two selection gates are arranged on the two sides of the floating gate MOSFET, and the selection gates are separated from the control gate and the photoelectron storage layer by an insulating medium material, and the substrate controlled by the control gate is separated from the source and the drain of the imaging detector. The second layer of insulating medium layer in contact with the control gate is a material for preventing the stored charges in the photoelectron storage layer from flowing to the control gate, and the first layer of insulating medium layer in contact with the substrate P-type semiconductor material, i.e. the bottom layer of medium, effectively isolates the substrate channel controlled by the control gate from the photoelectron storage layer, and when the gate voltage is high enough or the incident photon energy is high, the electrons in the channel are swept into the photoelectron storage layer. When a positive bias pulse is applied to the control gate and a negative bias pulse is applied to the P-type semiconductor substrate, a negative bias pulse is applied to the two selection gates, a depletion layer is formed in the P-type semiconductor substrate controlled by the control gate, and when the light is incident into the depletion layer, the photoelectrons are generated by the semiconductor absorption, and the photoelectrons are moved to the interface between the channel and the bottom insulating layer under the drive of the gate voltage. Since a negative bias is applied to the two selection gates, a high electron barrier is formed in the P-type semiconductor substrate controlled by the selection gate, which effectively separates the substrate controlled by the control gate from the N-type source and drain, thereby preventing the collected photoelectrons in the substrate depletion layer from flowing to the source and drain, and the electrons in the source and drain are also hindered by the high barrier from entering the substrate depletion layer. When the positive bias applied to the control gate is large enough, the collected photoelectrons in the substrate depletion layer will enter the photoelectron storage layer through F-N tunneling; if the incident photon energy is high enough, greater than the band gap width of the semiconductor and the bottom insulating medium layer, the photoelectrons can enter the photoelectron storage layer through direct tunneling. During the collection of photoelectrons, the source and the drain can be appropriately applied with a positive bias of appropriate size, or directly floated.
[0042] Preferably, the size of a single detector unit of the imaging chip is ≤1 μm, and the scale of the detector array is ≥100 million, so as to ensure a large field of view and high resolution during microscopic imaging of a liquid-based cell sample.
[0043] Preferably, the shape of the imaging hole and the culture groove is selected from one of an oval, a circle, a rectangle or a rounded parallelogram.
[0044] Preferably, the culture container and the top cover are both completely transparent and are made of glass or organic polymer.
[0045] The external control system comprises a control module, a light source module, a data acquisition and processing module, a data transmission module, an image analysis and display module, and a data storage module. The control module is connected to the light source module and the data acquisition and processing module. The data acquisition and processing module is also connected to the data transmission module. The data transmission module comprises at least one of a WIFI module, a Bluetooth module or a GSM module, and is connected to the image analysis and display module and the data storage module. The image analysis and display module is connected to the data storage module.
[0046] The control module can be an FPGA, which is used to control the imaging chip and the opening and closing of the light source module (lighting lamp) during imaging. After the data acquisition and processing module receives the microscopic images collected by the imaging chip, it removes and suppresses the noise in the projected microscopic images through relevant image processing algorithms, and processes the image data with poor imaging effects, such as weak signal, blurred edges, and low signal-to-noise ratio, through image enhancement, pseudo-color coloring and image segmentation.
[0047] The data transmission module comprises a WIFI module, a Bluetooth module or a GSM module, which is used to transmit the processed projected microscopic images collected by the chip during the cell culture process to the image analysis and display module and the data storage module.
[0048] The image analysis and display module is used to receive the processed image data for further interactive analysis and display of the final imaging results. It can be a mobile phone, a tablet computer, a notebook computer, etc. The interactive analysis includes deleting, reducing, enlarging, rotating, selecting a specific area and labeling a target of the image.
[0049] The data storage module is used to establish an image database to store the image data after the data acquisition and processing module or the image data after the image analysis and display module. The data storage module contains a database, which can be stored locally or on a cloud server. The data storage module saves the data processed by the data acquisition and processing module or the data after the image analysis and display module into the local database or uploads it to the cloud server through the network, and can search, add or delete, modify and back up the image data in the database.
[0050] The above technical solution has the following advantages or beneficial effects:
[0051] First, by directly setting the cell culture container above the image acquisition device, the image acquisition device can acquire images of the adherent cells through the opening, so that the adherent cells can be imaged without the objective, thereby effectively overcoming the limitation of small focal depth in microscopic imaging, and the imaging quality is clearer;
[0052] Second, the culture device can not only be a cell culture container, but also output the collected images to the controller through the image acquisition device, process the images to obtain the growth of the adherent cells, and output the growth data of the adherent cells to the external display terminal to directly record the growth data of the adherent cells, so that the growth data of the adherent cells can be obtained in real time, and the user can understand the growth of the adherent cells in real time;
[0053] Third, as long as the cell culture container is set above the image acquisition device, the adherent cells in the cell culture container can be monitored in real time, which not only improves the monitoring accuracy of the adherent cells, but also saves the real-time monitoring space, thereby reducing the monitoring cost.
