具体实施方式
以下将参考附图描述本发明的实施例模式。注意,本发明能以多种模式实施,并且本领域技术人员容易理解,在此公开的实施例模式和细节能以多种方式修改而不脱离本发明的目的和范围。因此,本发明不应解释为限于以下将给出的实施例的描述。注意,在描述实施例模式的所有图中,一些参考数字附属于相同部分或具有相似功能的部分,且省略其重复描述。
[实施例模式1]
参考图1对本发明的无线芯片的一个实施例模式进行描述。图1是无线芯片的截面图。
在本实施例模式的无线芯片中,具有场效应晶体管的芯片101和天线(以下,将其描述为贴片天线103)通过导电层102a和102b相连接。具体而言,形成于具有场效应晶体管的芯片101的表面上方的连接端子104a和贴片天线的供电层113通过导电层102a相连接。此外,形成于具有场效应晶体管的芯片101的表面上方的连接端子104b和用作贴片天线的地接触体的导电层112通过导电层102b相连接。此外,贴片天线103和具有场效应晶体管的芯片101的连接部分可以填充有底部填料(under fill)104。
贴片天线103包括介电层110;形成于介电层110的表面上方的第一导电层111;把介电层110夹在中间面对第一导电层111并形成于介电层110的另一表面上方的第二导电层112,和供电层113。第一导电层111用作辐射电极。第二导电层112用作地接触体。提供供电层113以使第一导电层111和第二导电层112不相互接触。此外,通过供电层113,从贴片天线向具有场效应晶体管的芯片、或者从具有场效应晶体管的芯片向贴片天线提供功率。注意,可以使用供电点代替供电层113。
在此,对贴片天线的结构进行描述。
贴片天线的介电层110可以利用陶瓷、有机树脂或者陶瓷和有机树脂的混合物形成。作为陶瓷的典型实例,可指定氧化铝、玻璃、镁橄榄石等。而且,可混合多种陶瓷。介电层110优选利用铁电材料形成,用于获得高介电常数。作为这种铁电材料的典型实例,可指定钛酸钡(BaTiO3)、钛酸铅(PbTiO3)、钛酸锶(SrTiO3)、锆酸铅(PbZrO3)、铌酸锂(LiNbO3)、钛酸锆铅(PZT)等。而且,可混合多种铁电材料。
此外,作为有机树脂,可适当地使用热固性树脂或热塑性树脂。作为有机树脂的典型实例,可以采用环氧树脂、酚树脂、聚丁二烯树脂、BT树脂、乙烯基苄基、聚富马酸、氟化物树脂(fluoride resin)等。而且,可混合多种有机树脂材料。
当用陶瓷和有机树脂的混合物形成介电层110时,优选将颗粒状陶瓷的颗粒散布到有机树脂中来形成介电层110。此时,介电层110所含颗粒状陶瓷的量优选为20体积%或更多和60体积%或更少。此外,陶瓷的颗粒尺寸优选为1至50μm。
介电层110的相对介电常数为2.6至150,优选为2.6至40。通过使用具有高相对介电常数的铁电材料,能降低贴片天线的体积。
可以用选自金、银、铜、钯、铂、和铝的金属或者合金等形成贴片天线的第一导电层111、第二导电层112、供电层113。此外,可以通过印刷方法或电镀方法形成贴片天线的第一导电层111、第二导电层112、供电层113。此外,在通过汽相沉积方法、溅射方法等在介电层上形成导电膜之后,可以通过蚀刻部分导电膜形成每一导电层。
贴片天线103的平面面积优选为几mm×几mm至几十mm×几十mm。典型实例是7mm×7mm至12mm×12mm。贴片天线的厚度是1mm至15mm,典型地为1.5mm至5mm。关于贴片天线的形状,贴片天线的平面表面优选是具有矩形平面表面的平板;然而,其不限于此。也可使用具有圆形平面表面的平板。注意,在此的平面表面是其中形成用作辐射电极的第一导电层或用作地接触体的第二导电层的一种平面表面。
参考图5A至5D对贴片天线的结构作出描述。
图5A示出了一种贴片天线,其具有用作辐射电极的第一导电层202;介电层201;用作地接触体的第二导电层203;供电点204,和电源馈电线(power feeder),其形成于在第一导电层202、介电层201和第二导电层203中提供的通孔中,并连接到供电点204。注意,电源馈电线连接到供电点204中的第一导电层202;然而,其不连接到第二导电层203。当用作辐射电极的第一导电层202是圆形形状且在关于一点相互对称的两个区域中存在退化分离元件205时,贴片天线是圆形极化波天线。同时,第一导电层202是圆形形状,贴片天线是线性极化波天线。
图5B示出了一种贴片天线,其具有用作辐射电极的第一导电层212;介电层211;用作地接触体的第二导电层213;供电点214,和电源馈电线,其形成于在第一导电层212、介电层211、和第二导电层213中提供的通孔中并连接到供电点214。注意,供电体连接到供电点214中的第一导电层212;然而,其不连接到第二导电层213。当用作辐射电极的第一导电层212是矩形的且在关于一点相互对称的两个角中存在退化分离元件215时,贴片天线是圆形极化波贴片天线。当第一导电层212是矩形形状时,贴片天线是线性极化波贴片天线。
图5C描述了一种贴片天线,其具有用作辐射电极的第一导电层222;介电层221;用作地接触体的第二导电层223,和供电层224。当用作辐射电极的第一导电层222是矩形的且退化分离元件225存在于关于一点相互对称的两个角中时,其是圆形极化波贴片天线。在第一导电层222是不具有退化分离元件225的矩形的情况下,贴片天线是线性极化波贴片天线。用作辐射电极的第一导电层222和供电层224通过间隙电容耦合。由于供电层224形成于介电层的侧表面上,因此可以进行表面安装。
由于图5A至5C中示出的贴片天线具有至介电层201、211和221的一个表面的用作地接触体的第二导电层203、213和223,因此它们在第一导电层202、212和222的侧处具有方向性。由此,电波被发射到第一导电层的侧。
图5D是一种贴片天线,其具有用作辐射电极的第一导电层242;介电层241;用作地接触体的第二导电层243,和供电层244。此外,如图5D中所示,正交缝隙在第一导电层242中成对角线形成。换句话说,十字形开口提供于用作辐射电极的第一导电层242中。因此,介电层241暴露于十字部分中。用作辐射电极的第一导电层242和供电层244通过间隙电容耦合。作为具有这种形状的贴片天线的典型实例,可指定CABPB1240、CABPB0730、CABPB0715(由TDK制造的产品)。由于供电层244形成于介电层241的侧表面上方,因此可以进行表面安装。具有这种结构的贴片天线由于用作辐射电极的第一电极层242的正交缝隙而不具有方向性,并由此,电波能在所有方向上发射。因此,不能决定安装空间或设置角。由此,可以在设计电子设备方面提高自由度。
此外,除了图5A至5D中所示的贴片天线之外还可使用已知的贴片天线。
特别地,通过使用圆形极化波的贴片天线,可以进行传输/接收如第三代数据通信、分组通信和GPS(全球定位系统(1.5GHz))的传输/接收、卫星数字广播(2.6GHz)、PAN(个人区域网)如无线LAN(局域网)(2.4GHz,5.2GHz)、用于连接信息设备的无线通信技术(蓝牙(商标)(2.4GHz))、或者UWB(超宽带)(3至10GHz)等。
参考图4对具有场效应晶体管的芯片101进行描述。
图4描述了具有场效应晶体管的芯片101的截面图。元件隔离区域501a至501e形成于结构500上方,场效应晶体管502形成于每个元件隔离区域501a至501e之间。
场效应晶体管502包括形成于单晶半导体衬底上方的栅绝缘膜503,形成于栅绝缘膜上方的栅电极504,在单晶半导体衬底中的源极和漏极区505a和505b,形成于栅电极上方的层间绝缘层508,以及连接到源极和漏极区505a和505b的源极和漏极布线509a和509b。注意,可以包括形成于栅电极504和栅绝缘膜503的侧壁处的侧壁507a和507b或者由单晶半导体衬底中的侧壁507a和507b覆盖的低浓度杂质区域506a和506b。
衬底500是单晶半导体衬底或者是化合物半导体衬底。作为典型实例,可指定n型或p型单晶硅衬底,GaAs衬底、InP衬底、GaN衬底、SiC衬底、蓝宝石衬底、ZnSe衬底等。可替换地,可使用SOI衬底(绝缘体上硅)。在该实施例模式中,使用n型单晶硅衬底作为衬底500。
元件隔离区域501a至501e适当地通过已知方法形成,例如LOCOS(硅的局部氧化)方法或沟槽隔离方法。在此,氧化硅层通过沟槽隔离方法形成,作为元件隔离区域501a至501e。
栅绝缘膜503通过热氧化单晶半导体衬底形成。栅电极504可以是厚度为100至300nm的多晶硅层,或者是包括形成于多晶硅层上方的硅化物层如硅化钨层、硅化钼层和硅化钴层的叠置结构。而且,氮化钨层和钨层可以叠置于多晶硅层上方。
对于源极和漏极区505a和505b,可使用其中将磷添加到p阱区中的n+区或将硼添加到n阱区中的p+区。对于低浓度杂质区域506a和506b,可使用其中将磷添加到p阱区中的n-区或将硼添加到n阱区中的p-区。在此,由于使用n型单晶硅衬底,因此形成通过添加硼至衬底形成的p+区的源极和漏极区,以及p-区的低浓度杂质区域。注意,硅化物如硅化锰、硅化钨、硅化钛、硅化钴和硅化镍可包括在源极和漏极区505a和505b中。通过在源极和漏极区的表面中具有硅化物,能降低源极和漏极布线以及源极和漏极区的连接电阻。
侧壁507a和507b在衬底上方通过CVD方法形成了使用氧化硅形成的绝缘层,且它们可以通过利用RIE(反应离子蚀刻)方法各向异性蚀刻绝缘层形成。
层间绝缘层508用无机绝缘材料形成,如氧化硅和氧氮化硅,或者由有机绝缘材料形成,如丙烯酸树脂和聚酰亚胺树脂(polyimidresin)。在使用涂覆方法如旋涂方法和辊涂机的情况下,在涂覆溶解在有机溶剂中的绝缘膜材料之后,可使用通过热处理用氧化硅形成的绝缘层。在此,层间绝缘层508用氧化硅形成。
源极和漏极布线509a和509b优选通过组合低值电阻器材料如铝(Al)和使用具有高熔点的金属材料的阻挡金属如钛(Ti)和钼(Mo)形成。具体而言,可指定钛(Ti)和铝(Al)的叠置结构以及钼(Mo)和铝(Al)的叠置结构。
除了场效应晶体管之外,具有场效应晶体管的芯片101还可以包括电阻器元件、电容器等。
层间绝缘层511形成于层间绝缘层508以及源极和漏极布线509a和509b上方。层间绝缘层511以与层间绝缘层508相同的方式形成。连接到场效应晶体管502的连接端子512和513提供于层间绝缘层508上方。
可以形成覆盖一部分的连接端子512和513以及层间绝缘层511的绝缘层514。由于绝缘层514用作保护层,因此优选其使用氮化硅、氧化硅、氧氮化硅、氮氧化硅、DLC(类金刚石碳)等形成。
连接贴片天线103和具有场效应晶体管的芯片101的导电层102a和102b用凸起、导电胶、抗扭曲(antistrophic)导电粘接剂、抗扭曲导电膜等形成。替换地,可以使用凸起和导电胶。而且,可使用凸起和抗扭曲导电粘接剂,或者凸起和抗扭曲导电膜。在这种情况下,导电层和连接端子通过凸起和导电颗粒相连接。
抗扭曲导电膜和抗扭曲导电粘接剂是粘性有机树脂,其中扩散了几nm至几μm的颗粒尺寸的导电颗粒。作为有机树脂,可指定环氧树脂、酚树脂等。导电颗粒用选自金、银、铜、钯或铂的一种或多种元素形成。替换地,可以使用具有这些元素的多层结构的颗粒。另外,可以使用其表面涂覆有薄膜的导电颗粒,该薄膜用选自金、银、铜、钯、或铂的一种或多种金属形成。该颗粒用树脂形成。
底部填料104具有加强具有场效应晶体管的芯片101和贴片天线103的连接部分、以及防止水从外部进入等的功能。底部填料104用环氧树脂、丙烯酸树脂、聚酰亚胺树脂等形成。
参考图6对本实施例模式中示出的无线芯片900的结构进行描述。本实施例模式的无线芯片900包括具有场效应晶体管的芯片901和天线902。
具有场效应晶体管的芯片901包括算术处理电路部分903、存储器部分904、通信电路部分905和电源部分907。存储器部分904包括仅用于读取的存储器,或者一个或两个可改写存储器。存储器部分904用选自静态RAM、EEPROM(电可擦除可编程只读存储器)、快闪存储器和有机存储器的一个或多个形成,从而在任何时候都能记录从外部通过天线902接收的数据。
注意,有机存储器是这样一种存储器,即具有有机化合物的层被提供于一对电极之间。另外,有机存储器是这样一种存储器,即在一对电极之间提供有机化合物和无机化合物的混合层。作为有机化合物的典型实例,可指定其结晶状态、导电性或者形状通过施加电压或者发光而改变的材料。通常,可以使用掺杂有通过吸收光而产生酸的化合物的共轭聚合物(光氧化产生剂)、具有空穴传输特性的有机化合物、或者具有电子传输特性的有机化合物。
由于有机存储器能实现其尺寸和厚度的降低,并同时增加其容量,因此通过使用有机存储器提供存储器部分904,无线芯片能实现其尺寸和重量的降低。
注意,可以形成存储器部分904的结构使得可以在任何时候写入。此外,存储器部分904可以具有其中数据不消失的浮置栅结构的存储元件。尤其,可以利用具有浮置栅结构并且其中仅能写入一次数据的存储元件。通过简化功能,能降低无线芯片的尺寸。而且,也能实现功耗降低。
通信电路部分905包括解调电路912和调制电路913。解调电路912解调通过天线902输入的信号,并将其输出至算术处理电路部分903。该信号包括将被存储在存储器部分904中的数据。从存储器部分904读出的数据通过算术处理电路部分903输出到调制电路913。调制电路913将信号调制为适合于无线通信的信号,并通过天线902输出到外部设备。
操作算术处理电路部分903、存储器部分904和通信电路部分905所需的电功率通过天线902提供。

在此,参考图14对由移动电话的数据解调和调制电路表示的高频电路的框图进行描述。
首先,对将由天线接收的信号传送到基带单元中的过程进行描述。所接收的被输入到天线301中的信号被从双工器(duplexer)302输入到低噪声放大器(LNA)303中并被放大成规定信号。所接收的被输入到低噪声放大器(LNA)303中的信号通过带通滤波器(BPF)304以被输入到混频器305中。RF信号从混合电路306输入到混频器305中,且RF信号分量在带通滤波器(BPF)307中被去除以便被解调。所接收的从混频器305输出的信号在通过SAW滤波器308之后在放大器309中被放大并被输入到混频器310中。规定频率的局部振荡信号被从局部振荡电路311输入到混频器310中,被转换成所需频率,并通过放大器312放大成规定水平。之后,将信号传输到基带单元313中。天线301、双工器302和低通滤波器328被描述为天线前端模块331。

如果检查设备将人体内部成像,则发光器件如LED(发光二极管)和EL可提供于检查设备中。结果,可以将人体内部成像。
提供于囊体表面中的保护层优选包括类金刚石碳(DLC)、氮化硅、氧化硅、氮化硅、氮氧化硅或者氮化碳。囊体和填料是适当选择的已知材料。通过在囊体中提供保护层,可以防止囊体或无线芯片在体内熔化和变性。
注意,如实施例模式3中所示的具有电池的无线芯片可用于传感器装置,以便将来自检查设备的所探测的结果的数据自动传输到读/写器。
接下来,对检查设备的方法进行描述。检查设备3950或3955被受检者3962吞下,且在体腔3963内移动。由无线芯片的传感器装置探测的结果被传输到设置在受检者附近的读/写器3961。读/写器接收这些结果。结果,受检者的生物体的功能数据可以当场被探测到,而不用收集无线芯片。而且,可获取体腔和消化器官的图像。
通过在受检者3962中嵌入检查设备3950或3955,如图13D中所示,将由无线芯片的传感器装置探测的结果传输到设置在受检者附近的读/写器3964。在这种情况下,检查设备3955嵌入到体内,以便使电极3956与受检者的身体的一部分接触以便进行测量。读/写器接收这些结果。所接收的结果被存储并被生物学数据管理计算机处理,可以管理受检者的生物学数据。此外,通过在床3960中提供读/写器3964,可以一直为由于身体功能缺陷而难于移动的受检者探测生物学数据。由此,能管理疾病状态和健康状况。
本实施例可以与上述实施例模式中的任何一个适当地组合。
[实施例2]
在本实施例中,参考图8A至10对通过传感器装置的探测方法和在具有传感器装置的无线芯片中所探测的数据的传输/接收方法进行描述。
图8A描述了探测环境或发光亮度的传感器装置的一个实例。传感器装置908具有传感器元件906和传感器电路909。传感器元件906利用光电二极管、光电晶体管等形成。传感器电路909包括传感器驱动电路952、探测电路153和A/D转换电路954。
图8B描述了探测电路953。如果用于复位的TFT 955是导通的,则将反向偏置施加到传感器元件906。在此,在负侧端子中传感器元件906的电势被充电至电源电压的电势,且该操作被称作复位。之后,使用于复位的TFT 955不导通。此时,由于传感器元件906的电动力,电势状态随着时间的过去而改变。换句话说,由于在光电转换中所产生的电荷,被充电到电源电压的电势的负侧端子中传感器元件906的电势逐渐降低。在经过一定时间之后,如果用于偏置的TFT 957导通,则信号通过用于放大的TFT 956输出到输出侧。在这种情况下,用于放大的TFT 956和用于偏置的TFT 957以所谓的源极跟随器电路的方式操作。图8B描述了其中源极跟随器电路由n沟道TFT形成的实例;然而,很明显,其可以由p沟道TFT形成。电源电压Vdd被加到放大侧的电源线958上。参考电势O伏特施加到偏置侧的电源线959。用于放大的TFT的漏极侧端子连接到放大侧的电源线,并且源极侧端子连接到用于偏置的TFT 957的漏极端子。用于偏置的TFT 957的源极侧端子连接到在偏置侧的电源线959。偏置电压Vb施加到用于偏置的TFT 957的栅极端子,并且偏置电流Ib流到该TFT。用于偏置的TFT 957基本上用作恒流源。输入电压Vin施加到用于放大的TFT 956的栅极端子,并且源极端子成为输出端子。源极跟随器电路的输入和输出关系表示如下:Vout=Vin-Vb。输出电压Vout通过A/D转换电路954被转换成数字信号。该数字信号被输出到算术处理电路部分903。
图9是描述数据管理设备401和具有传感器装置908的无线芯片900的操作的流程图。数据管理设备401传输控制信号如传感器装置启动信号、数据读取信号和数据写入信号。控制信号由无线芯片900接收。无线芯片900用算术处理电路区分控制信号。之后,确定进行以下三个操作中的哪一个操作:通过操作传感器元件906测量和存储数据;读取在存储器部分中存储的数据;和在存储器部分中写入数据。在数据的测量和存储操作中,操作传感器电路909,并读取传感器元件906的信号。然后,该信号通过传感器电路909被二进制化,并被存储在存储器部分中。在写入数据的操作中,从数据管理设备401传送的数据被写入到存储器部分904中。在读取存储在存储器部分中的数据的操作中,存储器部分904的数据被读出,并被传输到数据管理设备401。通过传输信号或者根据需要产生操作电路所需的功率。
接下来,参考图10对利用数据管理设备401的读/写器传输和接收由无线芯片的传感器装置908探测的数据的系统进行描述。图10描述了传输和接收本发明的无线芯片900和无线芯片900的数据的读/写器920的一个实例。读/写器920包括通信电路部分922,其具有天线921、传送器923、解调电路924和调制电路925。此外,包括算术处理电路部分926和外部接口部分927。为了通过加密传输和接收控制信号,包括加密/解密电路部分928和存储器部分929。电源电路部分930将电功率提供到每一个电路,并将从外部电源931提供的电功率提供给每一个电路。
在用算术处理电路部分903处理由无线芯片900的传感器装置908探测的数据之后,该数据被存储在存储器部分904中。由于无线芯片900的天线902中的电磁感应,在通过读/写器920的调制电路925之后作为电波被传输的信号942被转换成AC电信号。在通信电路部分905的解调电路912中,AC电信号在随后阶段中被解调并被传送到算术处理电路部分903。在算术处理电路部分903中,根据所输入的信号,召集(call up)被存储在存储器部分904中的由传感器装置探测的数据。之后,从算术处理电路部分903将该信号传输到调制电路913,并且该信号在调制电路913中被调制成AC电信号。之后,AC电信号941通过天线902被传输到读/写器920的天线921。
用读/写器920的天线921接收的AC电信号941用通信电路部分922的解调电路924解调,并在随后阶段中被传输到算术处理电路部分926和外部接口部分927。之后,通过传感器装置探测的数据在连接到外部接口部分927和数据管理设备401如计算机的显示器上被显示。
