Description
技术领域
本申请案涉及具有隔热及温度调节的集成电路。
背景技术
温度调节电路对于需要稳定电压或电流信号的仪器、计量及其它装置非常重要。形成在半导体衬底中或其上的电组件通常在操作中经受热漂移。散热及其它技术可帮助从集成电路(IC)的模制封装中去除热量。某些方法使用板上加热或热传递组件来控制IC中的电组件的温度。这些技术可与隔热结构耦合以促进组件温度的稳定。然而,这些方法是昂贵的并增加了功耗。IC中的组件也受机械应力影响,从而导致随温度变化的参数偏移及电势漂移。例如,已知的是,由于封装材料引起的热机械应力,例如晶体管的阈值电压、IC的高精度参考电压等电特性会漂移。低弹性模量的封装材料可用来增强应力免疫性,但是这些材料通常具有高热膨胀系数(CTE),且封装在这种材料中的IC装置由于应力及温度漂移两者而仍然受到参数变化的影响。
发明内容
所揭示实例包含集成电路,其具有包含腔体的模制封装及腔体内的半导体裸片。半导体裸片包含一或多个电组件,其中热控制组件及驱动器用于控制电组件的温度。半导体裸片在腔体内至少部分地与模制封装的内表面间隔开,以改善绝热以实现改善的温度稳定性。在某些实例中,半导体裸片102的全部外表面与模制封装结构106的内表面间隔开,且裸片由接合线附接件支撑以进一步增强绝热并减轻机械应力。

具体实施方式
在附图中,相同的元件符号在全文表示相同的元件,且各种特征不一定按比例绘制。在以下讨论及权利要求中,术语“包含(including)”、“包含(includes)”、“具有(having)”、“具有(has)”、“具有(with)”或其变体旨在以类似于术语“包括”的方式具有包含性,且因此应被解释为意指“包含但不限于...”。另外,术语“耦合(couple)”或“耦合(couples)”旨在包含间接或直接的电或机械连接或其组合。例如,如果第一装置耦合到第二装置或与第二装置耦合,那么可通过直接电连接或通过经由一或多个介入装置及连接进行的间接电连接来进行所述连接。
图1展示了具有半导体裸片102的集成电路(IC)100,所述半导体裸片102包含一或多个电组件104。在某些实例中,裸片102包含例如硅、SOI或其它半导体衬底等的衬底101,且所述组件104形成在衬底101上或衬底101中。在一个实例中,组件104是齐纳二极管,其用于产生用于IC 100或主电路(未展示)中的稳定电压参考信号。其它实例中的组件104是电阻器、电感器、电容器、电压参考、振荡器电路或其它频率时基或其组合,或高阶电路功能组件的其它单个组件(例如放大器、电压-电流转换器、A/D转换器等)。通过调节或以其它方式控制组件104的温度,可使用紧凑但不精确组件,其占用较小的面积同时提供热稳定性。
IC 100被容置在具有引线框结构的模制封装结构106中,所述引线框结构包含例如裸片或芯片焊盘等的基座107及多个电导体108。图1的实例是表面安装式IC 100,其中引线框电导体108具有暴露的平坦底表面以允许成品IC焊接到主印刷电路板(PCB,未展示)的对应衬垫用于电连接到裸片102。模制封装结构106可为对裸片102提供电绝缘及机械保护的任何合适的模制材料,且可包含低弹性模量材料以增强应力免疫性。所揭示的隔热及机械隔离技术及概念允许使用具有高热膨胀系数(CTE)及高热导率的模制封装材料106以节省成本,同时提供所述电组件104的温度稳定操作。
如图1中所示,模制封装106包含腔室或腔体110,且半导体裸片102在腔体110内与模制封装106的内表面全部或至少部分地间隔开。裸片102可以任何合适的方式被支撑在腔体110内,其中半导体裸片102的外表面的至少部分与模制封装结构腔体110的内表面间隔开。以此方式,外部裸片表面不与导热模制封装材料106或基座107接触。相反,裸片102通过模制封装腔体110中的空气或其它气体隔热,空气或其它气体通常具有较高绝热系数。这又促进在如下文进一步描述的操作期间对电组件104的温度进行内部控制。在各种替代实施例中,腔体110被抽空气体或以较低原子量的气体进行回填且经由膜114进行密封,以实现更高水平的绝热。
除了改善的热稳定性之外,某些所揭示的实例通过将电组件104及主裸片102完全或至少部分地与相关联于模制封装材料106的应力隔离来促进机械稳定性。在图1的实例中,半导体裸片102的整个外表面与模制封装结构106的内表面间隔开。在其它实例中,裸片102的表面的部分可在腔体110中与模制封装结构106的内表面接触,或与支撑结构等(例如,下面的图4)接触。
在图1中,裸片102由从引线框传导结构108延伸到内腔110中的接合线112悬挂。在用以形成模制封装材料106的模制工艺之前,接合线112焊接、超声波焊接或以其它方式连接到半导体裸片102的顶部上的接合垫113以在接合垫113与相关联的引线框传导结构108之间形成电连接。在图1的实例中,腔体110被覆盖腔体孔或孔隙116的膜层114密封。如所说明,孔116可位于腔体110的上部中,或腔体可穿过侧面或穿过底部或其组合穿孔。孔116可用于在形成模制结构106之后使用热蒸发或升华的升华材料或其它牺牲材料来促进悬挂裸片结构的制造,以使裸片102保持被接合线112悬挂,如图1中所示。在2016年8月26日申请的标题为“浮动裸片封装(Floating Die Package)”的第15/248,151号美国专利申请案中说明及描述了合适的制造工艺及材料,所述申请案的全部内容特此以引用方式并入。
在某些实例中,模制结构106覆盖或以其它方式密封半导体裸片102、引线框结构107、108的部分及接合线112。在一个实例中,腔体110通过在模制之前在半导体裸片102上方沉积牺牲囊封剂材料并对所述材料加热以使牺牲囊封剂材料通过模制结构106的孔116升华而形成。此过程留下了其中由于沉积在裸片102与基座107之间的裸片附接材料的升华或收缩/分层半导体裸片102在引线框基座107上方浮动的空间。然后,在模制结构106上方或模制结构106上形成膜层114以覆盖孔116并提供气密密封的IC结构100。裸片102的外表面与模制材料106的内表面的分离或间隔在裸片102的所有侧上提供气隙绝热,从而使接合线112成为到外部环境的唯一有效的热传导路径。接合线112的直径、长度、位置及数量将裸片维持在腔体110中的固定位置。此方法实现了仅硅裸片的低功耗、温度管理、快速上电及稳定时间、最小及受管理的热电偶效应及几乎没有由于机械应力及迟滞引起的参数电偏移。
如图1中所示,根据一个实施例,裸片102包含电阻式热控制电路R1、R2、118、120以调节或以其它方式控制电组件104的温度。可使用其它热控制电路,无论是开环还是闭环的。所揭示的实例通过遍及整个装置集成温度控制、热路径管理及硅裸片102与机械应力源的隔离来促进对电组件104的操作温度的调节使其在很大程度地或完全独立于外部温度及机械应力。图1中的半导体裸片102包含形成温度补偿电路的一或多个热控制组件。所述实例包含:电阻器R1及R2,其与电组件104进行热传导以控制电组件104的温度;及驱动器118,其用于至少部分地根据设置点信号SP向热控制组件R1、R2提供电流或电压信号或波形。在一些实例中,驱动器118向热控制电路施加特定的时变信号,例如周期性脉冲或正弦波。
在某些实施例中包含例如二极管120等热传感器以在浮动硅裸片102中提供加热器及闭环伺服控制。在一个实例中,热感测组件120由供应电流源(未展示)偏置且在物理上靠近电组件104。传感器120感测电组件104的温度且向驱动器118的非反相输入提供第一信号。在一个实例中,传感器120向驱动器放大器118的输入提供电压信号。在一个实例中,固定设置点SP信号从裸片102的电压源被提供给驱动器放大器118的反相输入。在其它实例中,设置点信号SP是可调的,且可在制造或校准期间进行修整。在此实例中,驱动器从热传感器120接收反馈信号,并以闭环方式向热控制组件R1及R2提供电流或电压信号,以将反馈信号驱动到设置点信号SP的电平。这将电组件104的温度调节到对应于设置点信号SP的温度。
图2展示了另一IC实施例100,其包含悬挂在模制封装结构腔体110中的半导体裸片102。在此实例中,使用热电结构200来向电组件104提供热量或从电组件104中去除热量。在一个实施方案中,热电结构200是珀耳帖(Peltier)材料结构,例如印刷在硅衬底101的上表面上的绝热且电绝缘厚氧化物材料204上的碲化铋的n掺杂纳米颗粒。电介质层204可为包含一或多个导电特征的金属化结构的一或多个层间电介质层。在此实例中,热电结构200形成为具有内部间隙的环形结构,所述内部间隙使电介质材料层204的上孔暴露于腔体110的环境。热电结构200从裸片102的内部间隙横向向外延伸到横向边缘。在此实例中,裸片102包含导热且导电内部环形环结构202,其在衬底101的顶侧的环形内部部分与热电材料层200的环形内部部分之间穿过电介质层204而形成。内部环形环结构202在衬底101与热电材料层200之间提供内部环形导热路径。
导热且导电外部环形环结构113形成为金属环结构,其上存在接合线连接的多个实例。结构113在靠近半导体裸片102的横向边缘处与内部环形环结构202横向向外间隔开。包含一或多个接合垫113的外部环形环结构经定位成与热电材料层200且与接合垫113及接合线112进行热传导。外部环形环结构113在内部环形环结构202之间提供横向热传导路径且包含接合垫以在裸片102与接合线112之间传递热量。驱动器118包含连接到外环形环结构113的输出206。驱动器118向热电结构200提供电流或电压信号,以选择性地向电组件104提供热量或从电组件104中去除热量。这产生了从受保护的电组件104附近的衬底101,穿过内部环形环结构202,横向穿过热电材料层200且然后穿过外部环形结构113的接合垫及接合线112到引线框传导结构108的迂回导热路径208。驱动器118以加热模式或冷却模式提供温度伺服回路以驱动热电材料结构200。图2的实例允许在较低的温度下进行裸片调节,并允许环境温度具有较宽的可允许变化。
图3展示了另一IC实施例100,其包含悬挂在模制封装结构腔体110中的半导体裸片102。此实例包含具有热电材料层200的多级热电结构以及用于控制电组件温度的导热且导电环形环结构300。环形导电环结构300在电介质层204的顶侧上彼此横向向外间隔开,且包含:内部环形传导结构300,其至少部分地形成在内部环形环结构202上;及外部环形传导结构300,其经形成靠近半导体裸片102的横向边缘且与接合垫113进行热传导。热电材料结构200包含热电材料200,其形成在环形传导结构300之间的电介质层204的顶侧的部分上方以在内部环形环结构202与接合垫113之间阶段性地传递热量。此结构跨与硅衬底101热连接的内部环形环及与接合垫113及接合线112进行热传导的外部环形环之间的表面横向地提供热抽吸。接合线112通过模制材料106及到封装衬垫108及电路板(未展示)的金属路径两者向环境温度提供散热。虽然不是对所有实施例的严格要求,但是在环300之间印刷有热电材料200的一或多个抽送级,且材料200可如所示那样覆盖环300。如图3中所示,环300传导电流I3、I2及I1,且迂回热路径208如上文结合图2所述用以提供包含电组件104的热控制区。
图4展示了另一IC实施例100,其中散热到环境是通过裸片附接路径以及接合线路径进行。图4中的IC 100包含如上所述那样悬挂在模制封装结构腔体110中的半导体裸片102以及热电结构200。半导体裸片102用垂直沟槽400图案化为环形图案。在某些实例中,沟槽至少部分地填充有绝热材料。在某些实例中,沟槽400可延伸到半导体裸片102的底部。在其它实例中,例如图4中所示,沟槽没有一直延伸到裸片102的底部。传导结构402穿过电介质层204形成在外部环形环300与衬底101的横向外端之间。另外,材料200如上文结合图2所述那样提供向外热传导路径208。半导体裸片102包含一或多个裸片附接结构406,其在引线框基部结构107与衬底101的底侧的靠近半导体裸片102的横向边缘的部分之间延伸以提供垂直热传导路径408以在半导体裸片102与引线框基部结构107之间传递热量。在沟槽400没有一直延伸到裸片102的底部时,热泄漏路径410可存在于沟槽400的底部下面。图4的实施例还包含垂直沟槽400,其从电介质层204的底侧部分地或完全延伸穿过101。在某些实例中,此类沟槽用比硅101的导热率低得多的材料回填。垂直沟槽在半导体裸片102的横向边缘与衬底101的包含电组件104的中间部分之间彼此横向地间隔开。这些沟槽使区域104、118、120的硅101与101的接触406的外部环形部分横向隔热。
现在参考图5,电路可经分段以使如上所述那样在一个(例如,较小的)裸片102上的低功率、精确、温度管理的组件与囊封在模制封装结构106中的第二裸片502分离。在某些实例中,第二裸片502可大于第一裸片102,且包含可或不可处置较高功率负载的另外的电路。如所示,可使用裸片附接结构504将第二裸片502安装在引线框基部结构107上。一或多个额外的接合线512将第二裸片502与第一裸片102的接合垫中的一者连接,且接合线514将第二裸片502与引线框结构的电导体108连接。
现在参考图6到8,图6展示了另一IC实施例100,其包含如先前所述那样悬挂在模制封装结构腔体110中的半导体裸片102。在此实例中,裸片102包含具有设置点产生器电路600的热控制电路。如上文所讨论,热控制可为开环或闭环的。图7展示了在图6的集成电路中具有波形产生器电路700及开关电路的实例设置点产生器600。波形产生器700包含向单极三掷开关电路S1提供信号的输出702,所述单极三掷开关电路S1向如上所述的误差及驱动放大器118提供设置点信号SP。开关S1被展示在标记为“启动”的中心位置,以从波形产生器电路700的输出702接收输出信号。在一个可能的实施方案中,如下文结合图8进一步描述,在IC 102的启动期间使用波形产生器700。在正常操作期间,开关S1的第二输入704被标记为“运行”且从参考电压源706接收固定参考电压信号VREF。
第三输入708连接到IC 100的对应导体108,以从测试台或其它外部源(未展示)接收信号以在制造期间在不同的受控温度设置下进行测试。裸片102的隔热提供了在制造期间针对IC 100实施先进的测试及校准的能力。例如,可在若干温度下测试电压参考集成电路产品102以计算温度系数,且然后对所述产品进行电修整以降低所述温度系数(使得当参考受温度控制于固定温度时将实现非常高的精度)。“测试”开关设置允许外部参考源迫使电组件温度达到各个点。裸片102在腔体110中的隔热促进电组件104的温度的快速控制,以有助于在多个温度下进行快速测试。另外,在某些实例中使用波形产生器700在板上实施测试,而不需要昂贵的烤箱或其它外部热控制装置来热锻炼IC 100。在某些实施例中,温度调节回路在装置测试及修整期间经修改以实现多温度生产测试的低成本室温传真。此能力促进多温度参数验收测试、装置特征化、嵌入式组件的温度系数修整校正、极端温度下的异常检测、高温预处理、预老化及烧入。
在各种实施方案中,可在装置启动时采用阻尼循环迟滞温度控制算法来去除残留在硅设计(硅-金属)中的二阶应力假象。图8提供展示作为曲线802的额定信号电压VSP的信号图800及展示图6及7的实施例中的温度波形曲线812的图形810。在一个实例中,波形产生器700在启动期间将设置点信号SP作为多级阻尼迟滞波形802提供给驱动器118。曲线812展示了在施加设置点波形802期间裸片102中的电组件104的对应温度。在此实例中,波形产生器700在递减的包络中施加交替的高电平及低电平。IC裸片受到与硅对表面金属互连相关联的应力问题的影响。此类应力可在电组件104的操作中产生偏移。
在所揭示的实例中,电组件104的隔热及机械隔离提供了通过在IC启动时及/或在制造期间改变设置点信号SP来计算硅-金属界面的残余迟滞应力以实现改善的精度用于信号或频率参考类型的电组件或电路104。例如,如果IC在精确的操作温度点处进行生产修整,那么随后的热漂移可能会略微使参考值偏移。波形产生器700可用于通过执行受控温度漂移(例如图8中的多级阻尼迟滞波形802)将硅的迟滞记忆复位为已知点。在生产修整之前,根据图8的轮廓对组件104进行热锻炼。然后,在图8的稳定状态点处对所述部分进行生产修整。在应用中,在启动时,所述部分经热锻炼成与图8的轮廓相同,从而允许在启动之前引入到硅中的任何应力被复位到在装置修整时经历的相同条件,从而产生相同的精确电路响应。在制造期间,IC 100可被修整到特定温度点(例如,摄氏30度)。在启动时,组件104在启动时的点之上及之下进行热锻炼。在一个实例中,启动波形802以修整设置开始及结束,且此电平对应于在后续电路操作期间由电压源706提供的固定参考信号VREF。波形的又一用途是确定从受热组件到环境的热阻。如果区域102的排空完全,那么热阻将更高。如果排空不完全,那么热阻将会降低。热阻可通过温度传感器120上的波形的上升及下降时间来指示,且还可由温度传感器120上的信号的振幅来指示。以此方式,使用波形可指示不完整的处理或制造缺陷。此信息可用于拒绝不良装置并改善制造工艺控制。
所揭示的实例使用裸片上热控制电路提供一或多个电组件的隔热。这有利地避免或减轻了与加热裸片及封装以及周围PC板的部分的常规技术相关联的问题及成本。由于热加热电路仅需要加热浮动裸片102,因此当前揭示的技术及设备的优点是改善具有低功率开销的硅的热调节及由于低热质量而使温度快速稳定到受控值。另外,所揭示实例促进直接管理及消除热电偶诱导误差、消除热诱导迟滞应力误差源。另外,所揭示技术提供了热损耗的降低,使得在环境温度在非常宽的范围内变化时,所印刷的珀尔帖或其它热电元件可用于热调节到较低的温度(例如,30℃)。另外,所揭示设计提供了硅裸片102上及穿过封装及引线框结构的热流路径的直接管理。这些益处实现了装置的低成本、封装中多温度测试及修整,如图6到8中所示,并促进低成本、板上装置烧入及加速老化以及封装中温度控制算法以去除残余二阶应力假象。
以上实例仅说明本发明的各种方面的若干可行实施例,其中所属领域的其它技术人员在阅读并理解本说明书及附图之后将设想到等效更改及/或修改。修改在所描述的实施例中是可行的,并且其它实施例在权利要求书的范围内是可行的。
