图1为本身请的图像传感装置200的实施例的示意图。图像传感装置200包括像素阵列100，至少包括像素101a、101b，其中像素101a为一般像素，主要用来感测可见光，例如用作一般拜耳图案中的红色、蓝色或绿色像素；像素101b为高感光像素，例如用作白色像素，但应注意的是，此处的白色像素和一般的白色像素不同之处在于，像素101b除了用来感测可见光以外，还可用来感测红外光，其细节说明如下。FIG. 1 is a schematic diagram of an embodiment of a self-contained image sensing device 200 . The image sensing device 200 includes a pixel array 100, including at least

pixels

101a and 101b, wherein the pixel 101a is a general pixel and is mainly used for sensing visible light, for example, used as a red, blue or green pixel in a general Bayer pattern; the pixel 101b is A high-sensitivity pixel, for example, is used as a white pixel, but it should be noted that the difference between the white pixel here and the general white pixel is that the pixel 101b can also be used to sense infrared light in addition to the visible light. Details are as follows.

像素阵列100之上还包括滤波层112以及透镜114，并构成图像传感装置200，使光线进入像素阵列100之前，会依序先经过透镜114和滤波层112。像素101a和101b分别包括设置于半导体基底102中的光电二极管104a和104b。在光电二极管104a和104b之上和微透镜110a、110b之间，具有两层滤波层106和108。本申请的创新之处即在于利用不同以往的滤波层112、106和108设计，来使像素101a为只一般的红色、蓝色或绿色像素，同时又让像素101b除了用来感测可见光以外，还可用来感测红外光。如此一来，像素101b可以通过红外光来弥补可见光源不足时，单靠像素101a所造成的感测效果不佳的情况。也就是说，本案的像素101b可用来感测环境中的红外光以辅助像素101a，或是在某些实施例中，亦可额外在图像传感装置200感测时，利用红外光发射器作为辅助的闪光灯使用，以增强光源。在此应用下，像素阵列100中的像素101a的数量远多于像素101b的数量，例如像素阵列100中的像素101a的数量大于像素101b的数量的10倍。The pixel array 100 further includes a filter layer 112 and a lens 114 , and constitutes an image sensing device 200 . Before entering the pixel array 100 , light will pass through the lens 114 and the filter layer 112 in sequence.

Pixels

101a and 101b respectively include

photodiodes

104a and 104b disposed in semiconductor substrate 102 . There are two

filter layers

106 and 108 above the

photodiodes

104a and 104b and between the

microlenses

110a, 110b. The innovation of the present application is to use different designs of the

filter layers

112, 106 and 108, so that the pixel 101a is only a general red, blue or green pixel, and at the same time, the pixel 101b is not only used for sensing visible light, Can also be used to sense infrared light. In this way, the pixel 101b can use infrared light to make up for the poor sensing effect caused by the pixel 101a alone when the visible light source is insufficient. That is to say, the pixel 101b of this application can be used to sense infrared light in the environment to assist the pixel 101a, or in some embodiments, an infrared light emitter can be used as an additional sensor when the image sensing device 200 senses. Auxiliary flash is used to enhance the light source. In this application, the number of pixels 101a in the pixel array 100 is much more than the number of pixels 101b, eg, the number of pixels 101a in the pixel array 100 is more than 10 times the number of pixels 101b.

应注意的是，本发明不对像素101a和101b的数量和排列方式另做限制，在某些实施例中，像素阵列100主要用于感测红外光，因此可以依靠像素101a所提供的红色、蓝色或绿色颜色信息，来为像素101b所形成的亮度图像提供色彩还原的辅助。在此应用下，像素阵列100中的像素101b的数量远多于像素101a的数量，例如像素阵列100中的像素101b的数量大于像素101a的数量的10倍。It should be noted that the present invention does not limit the number and arrangement of the

pixels

101a and 101b. In some embodiments, the pixel array 100 is mainly used for sensing infrared light, so it can rely on the red and blue colors provided by the pixel 101a. Color or green color information to provide color reproduction assistance for the luminance image formed by the pixel 101b. In this application, the number of pixels 101b in the pixel array 100 is much more than the number of pixels 101a, eg, the number of pixels 101b in the pixel array 100 is more than 10 times the number of pixels 101a.

由于习知的彩色图像传感装置，会在光线进入微透镜110a、110b之前，先使用红外光截止滤波层(即滤波层112的已知实现方式)将红外光滤除，因此进入像素阵列的只剩下可见光而不会有红外光。本申请的滤波层112则是使可见光和红外光通过。Since the conventional color image sensing device uses an infrared cut filter layer (ie, a known implementation of the filter layer 112 ) to filter out the infrared light before the light enters the

microlenses

110 a and 110 b , the infrared light entering the pixel array is filtered out. Only visible light is left and no infrared light is left. The filter layer 112 of the present application allows visible light and infrared light to pass through.

对于像素101a来说，其目的在于使光电二极管104a感测到红色、蓝色或绿色的可见光，在本实施例中，滤波层106中对应像素101a的部分106a，用来使可见光通过，并将红外光滤除，功能如同红外光截止滤波层，具体来说，在本实施例中，如图2所示，图2 为滤波层106a的透射光谱图(transmission spectra)，即不同波长(nm)的光经过滤波层106a的穿透率(％)的示意图。滤波层106a使波段为约650纳米到至少约940纳米的紅外光不通过；滤波层108中对应像素101a的部分108a为红色(R)、蓝色(B)或绿色(G)滤光层，用来使红色、蓝色或绿色波段的光通过，和一般的R、G、B彩色滤波器相同。总的来说，滤波层106a和108a可使光电二极管104a接受到红色、蓝色或绿色波段的可见光。如图3所示，图3为红色(R)、蓝色(B)和绿色(G)类型的滤光层108a的透射光谱图。其中302代表光经过蓝色(B)滤光层108a的穿透行为；304代表光经过绿色(G)滤光层108a的穿透行为；306代表光经过红色(R)滤光层108a的穿透行为。图3中波段区间312(即约400纳米到约650纳米)中带有的红色(R)、蓝色(B)或绿色(G)信息是像素101a所需要保留下来的，而波段区间310(即约400纳米内)和波段区间314(即约650纳米以上)的信息对像素101a来说是不需要的，可分别通过滤波层112和滤波层106a滤除。For the pixel 101a, the purpose is to allow the photodiode 104a to sense red, blue or green visible light. In this embodiment, the portion 106a of the filter layer 106 corresponding to the pixel 101a is used to pass the visible light and transmit the visible light. Infrared light filtering has the same function as the infrared light cut-off filter layer. Specifically, in this embodiment, as shown in FIG. 2, FIG. 2 is a transmission spectrum of the filter layer 106a, that is, different wavelengths (nm) A schematic diagram of the transmittance (%) of the light passing through the filter layer 106a. The filter layer 106a does not pass infrared light with a wavelength band of about 650 nanometers to at least about 940 nanometers; the portion 108a of the filter layer 108 corresponding to the pixel 101a is a red (R), blue (B) or green (G) filter layer, It is used to pass light in the red, blue or green band, the same as the general R, G, B color filter. In general, the

filter layers

106a and 108a allow the photodiode 104a to receive visible light in the red, blue or green wavelength bands. As shown in FIG. 3, FIG. 3 is a transmission spectrum diagram of the red (R), blue (B) and green (G) type filter layers 108a. 302 represents the penetration behavior of light through the blue (B) filter layer 108a; 304 represents the penetration behavior of light through the green (G) filter layer 108a; 306 represents the penetration behavior of light through the red (R) filter layer 108a transparent behavior. The red (R), blue (B) or green (G) information in the band interval 312 (ie, about 400 nanometers to about 650 nanometers) in FIG. 3 is what the pixel 101a needs to retain, while the band interval 310 ( Information in the wavelength range 314 (ie, within about 400 nanometers) and the wavelength range 314 (ie, more than about 650 nanometers) is unnecessary for the pixel 101a, and can be filtered out by the filter layer 112 and the filter layer 106a, respectively.

而滤波层106中对应像素101b的部分106b和滤波层108中对应像素101b的部分108b，均可使可见光和红外光通过，换句话说，可使全波段的光通过。The portion 106b of the filter layer 106 corresponding to the pixel 101b and the portion 108b of the filter layer 108 corresponding to the pixel 101b can both allow visible light and infrared light to pass, in other words, light in all wavelengths can pass.

以单一滤波层实现滤波层106a的带通范围可能有工艺上的难度，因此在某些实施例中，可将滤波层106分两层来实现，例如图4所示，滤波层106中对应像素101a的部分106a可包含子滤波层1061a和子滤波层1062a，皆用来使可见光通过，并将红外光滤除，但负责的带通范围不同，子滤波层1061a和子滤波层1062a合并来看则功能如同滤波层106a。图5为依据一实施例的子滤波层1061a的透射光谱图；图6为依据一实施例的子滤波层1062a的透射光谱图。其中子滤波层1061a使波段为约650纳米到至少约850纳米的紅外光不通过；子滤波层1062a使波段为约800纳米到至少约940纳米的紅外光不通过。在图5和图6的实施例中，子滤波层1061a的带通波段和子滤波层1062a的带通波段部分重叠且部分不重叠，但本申请不以此为限。It may be difficult to realize the bandpass range of the filter layer 106a with a single filter layer. Therefore, in some embodiments, the filter layer 106 can be implemented in two layers. For example, as shown in FIG. 4 , the corresponding pixels in the filter layer 106 The part 106a of 101a may include a sub-filter layer 1061a and a sub-filter layer 1062a, both of which are used to pass visible light and filter out infrared light, but the responsible bandpass ranges are different. Like filter layer 106a. FIG. 5 is a transmission spectrum diagram of the sub-filter layer 1061a according to an embodiment; FIG. 6 is a transmission spectrum diagram of the sub-filter layer 1062a according to an embodiment. The sub-filter layer 1061a blocks infrared light with a wavelength band of about 650 nanometers to at least about 850 nanometers; the sub-filter layer 1062a blocks infrared light with a wavelength band of about 800 nanometers to at least about 940 nanometers. In the embodiments of FIG. 5 and FIG. 6 , the band-pass band of the sub-filter layer 1061a and the band-pass band of the sub-filter layer 1062a partially overlap and partially do not overlap, but the present application is not limited to this.

而滤波层106中对应像素101b的部分106b中的子滤波层1061b和子滤波层1062b均可使可见光和红外光通过，换句话说，可使全波段的光通过。The sub-filter layer 1061b and the sub-filter layer 1062b in the portion 106b of the filter layer 106 corresponding to the pixel 101b can both allow visible light and infrared light to pass, in other words, light in all wavelengths can pass.

在某些实施例中，可以将滤波层106和108对调。此外，在某些实施例中，滤波层112可设置于微透镜110a、110b的表面，例如以镀膜的方式形成于微透镜110a、110b相对于滤波层108的另一侧的表面，如图7所示。或，在某些实施例中，滤波层112可设置于镜头114的表面，例如以镀膜的方式形成于镜头114于像素阵列100的同一侧的表面，如图8所示。In some embodiments, filter layers 106 and 108 may be reversed. In addition, in some embodiments, the filter layer 112 may be disposed on the surface of the microlenses 110a, 110b, for example, formed on the surface of the microlens 110a, 110b on the other side of the microlens 110a, 110b relative to the filter layer 108, as shown in FIG. 7 shown. Or, in some embodiments, the filter layer 112 may be disposed on the surface of the lens 114 , for example, formed on the surface of the lens 114 on the same side of the pixel array 100 by means of coating, as shown in FIG. 8 .

图9为图像传感装置200/400/700/800应用在电子装置900的实施例的示意图。在某些实施例中，电子装置900可另包含红外光发射器(红外光闪光灯)500，图10为图像传感装置200/400/700/800的滤波层112的透射光谱图，具体来说，滤波层112应让红外光发射器500所发射的红外光能够穿过，亦即当红外光发射器500所发射的红外光的波长为850纳米时，滤波层112应能至少使波段为400纳米到至少850纳米的光通过，如图10的1002所示；当红外光发射器500所发射的红外光的波长为940纳米时，滤波层112应能至少使波段为400纳米到至少940纳米的光通过，如图10的1004所示。在某些实施例中，电子装置900可另包含一般可见光闪光灯(未绘示于图中)。电子装置900可为例如智能型手机、个人数字助理、手持式计算机***或平板计算机等任何电子装置。FIG. 9 is a schematic diagram of an embodiment in which the image sensing device 200/400/700/800 is applied to an electronic device 900 . In some embodiments, the electronic device 900 may further include an infrared light emitter (infrared light flash) 500. FIG. 10 is a transmission spectrum diagram of the filter layer 112 of the image sensing device 200/400/700/800, specifically , the filter layer 112 should allow the infrared light emitted by the infrared light emitter 500 to pass through, that is, when the wavelength of the infrared light emitted by the infrared light emitter 500 is 850 nm, the filter layer 112 should be able to make the wavelength of the infrared light at least 400 nm. The light from nanometers to at least 850 nanometers passes through, as shown by 1002 in FIG. 10; when the wavelength of the infrared light emitted by the infrared light emitter 500 is 940 nanometers, the filter layer 112 should be able to make the wavelength range from at least 400 nanometers to at least 940 nanometers. The light passes through, as shown at 1004 in Figure 10. In some embodiments, the electronic device 900 may further include a general visible light flash (not shown in the figure). Electronic device 900 may be any electronic device such as a smartphone, personal digital assistant, handheld computer system, or tablet computer.
