Abstract
本发明涉及隔离栅双极型晶体管,它生产方法简单,但仍可以均一地开启。为此目的,本发明的晶体管没有任何栅指,并在IGBT芯片内的栅电流从栅接线端出发,直接经栅极多晶硅层传输到IGBT单元。
Description
技术领域
本发明涉及半导体技术领域。尤其涉及权利要求1的前序部分的IGBT(隔离栅双极型晶体管)。这种IGBT可见于德国专利公开说明书DE 196 12 516 A1。
技术现状
按当前技术构造的IGBT内,具有0.2cm2极小表面的IGBT芯片的栅极信号首先借助于栅极导片分布在芯片的周边上(参阅DE 196 12516 A1)。窄带状栅(栅指)随后把这信号引入芯片内部(详见EP 0755 076 A2)。无论栅极导片或栅指都由铝金属化层形成。信号也可从安排在一个角上或中央的栅极垫片出发经栅指分布在芯片表面上(见图1)。一般采用的设计规则指出,栅指的间距x必须满足以下条件。
R是多晶硅的薄层电阻,它把信号从栅指引到实际的栅极,c是单位面积栅极的MOS电容量,τ是由τ=RGate·Ctot给出的IGBT的特征开关时间,RGate是栅极偏置电阻,Ctot是芯片总MOS电容量,典型值是c=30nF/cm2,R=30欧姆,τ=200纳秒。这样x<<0.47cm。如果满足上述条件,则在导通期间,与栅极偏置电阻无关,任一时刻栅极上的电压分布是平缓的,因而电流密度是均匀的。
然而如果需要阴极侧焊接,则栅指需要复杂且昂贵的焊接金属化,及对钝化提出很高要求。钝化缺陷导至栅极发射极短路,这表现为早期失效,且只有通过昂贵的老化试验才可以发现。类似的问题在压力接触情况下会出现。
发明描述
本发明的任务是提供制造方式简单,但仍然可以均一开启的IGBT。该任务通过独立权利要求的特征来解决。
本发明的核心是:IGBT芯片的栅极电流从栅接线端出发,不用栅指,直接经栅极的多晶硅层转接到IGBT-单元。栅极信号按照第1实施例可以经安排在一个角上的栅接线端(栅极垫片)或按照第2实施例经一个中央栅接线端输入到IGBT芯片。
因此本发明恰恰有别于目前主导的观点,即从一定的芯片尺寸起,只在应用栅指的情况下才能达到均一接通。更确切地说本发明人第一次认识到,与适用于MOS晶体管的设计规则不同的另外的设计规则适用于IGBT均一关断。本发明人尤其发现,当等离子体分布还是均匀时,最大损耗功率密度总是均匀的。特别是在MOS电流不再能够用来维持外部电流时,一个双极型器件表现出基本上不同于单极型器件的性能,如MOS晶体管。在该时刻之后,从双极型电流过渡到纯空穴电流,并与主结的耗尽相联系。一旦这个过程中止,则全部电流由空穴输运,并且形成空间电荷区。但是,等离子分布横向总还是相当均匀的。因此,极不均匀的电流分布也会很快均匀化。在最大功率耗损时,电流分布差不多是均匀的。因此安全运行区并不减小,而且关断能量几乎不变。结果可以制造没有栅指的IGBT,尽管超过了适合无栅指MOS晶体管的0.2cm2最小面积。
图2a和2b示出本发明的IGBT-芯片1的一个实施例。示出的主接线端3被绝缘体7和栅极性8包围。栅极性8与栅接线端4相连,从接线端4例如可以把压焊丝连接至相应的外壳引线端。与此相反,在按照图1a和1b的当前技术中安排了栅指6,它从栅接线端4出发,将栅极信号分布在芯片表面。
本发明的优点尤其在于:
-通过去掉栅指使简单和低成本地实施焊接金属化成为可能。
-较简单的工艺使对芯片压触时,较高的可靠性成为可能。

发明实施途径
在预试验中,制造了具有0.2cm2最小表面没有栅指的慢速2.5kV芯片并测量其特性。它在误差范围内与带栅指的类型没有差别。然而令人担心的是,快速芯片没有栅指的话可能会在极不均匀的电流分布情况下关断,因此会具有高的开关损耗、缓慢瞬变过程以及小的SOA。然而开关特性的分析计算、数字模拟以及没有栅指的快速IGBT的开关试验给出令人惊愕的结果。事实表明在关断时与开关时间τ可比较的信号传输时间并非一定导至不均匀的电流分布。试验还表明,与关断相比,接通是非关键的。对于进行芯片周边的栅极控制和选择
的情况,在关断时首先出现电流重新分布。芯片外部开始关断,负荷维持总电流恒定,并将电流引入芯片中央。在此时刻阳极电压基本上还是零。
在此时刻,MOS电流不再够用于维持外部电流。在纯MOS晶体管内,现在开始电压上升。电压上升是这样经栅-阳极(密勒效应)将电容电荷耦合到栅极,使得在栅极上的电压分布维持恒定,并且电流不再下降。一旦达到满负载电压,则调节机制中止栅压下降且使器件关断。
本发明的核心是,识别和充分利用双极型器件从上述时刻起主要表现出的另一种性能。在该时刻之后,与主结耗尽相联系双极型电流过渡到纯空穴电流。一旦该过程中止,则全部电流由空穴输运,而且形成空间电荷区。但等离子区横向仍旧维持均匀分布。因此,在该时刻极其不均匀的电流分布快速均匀化。到最大耗损功率时,电流分布几乎是均匀的。因此安全运行区不减小且关断能量几乎不变。因此,可以制造没有栅指也行的IGBT。
图2a和2b为由俯视或透视示出的按本发明的无栅指IGBT芯片1,它具有可见的第1主接线端3和未示出的第2主接线端以及栅接线端4,该接线端4在由图2a、2b所示实施例内安排在IGBT-芯片1的边缘,尤其是在一个角上。与展示现有技术的图1a和1b相反,它没有栅指6,而是栅极信号从栅接线端4出发经栅极性8分布在周边上。如图2b所看到的,栅极框8也是直接与栅极5有效连接的。栅极框最好具有小于5欧姆的电阻。
因此,第1主接线端3经一面形成,该面直到栅极引线4的凹槽为止是凸出的。其中在图2a和2b的实施例情况下,其凸出构形的面区被栅极性8所包围。如果存在多个栅接线端4,则第1主接线端的实际凸出的面具有相应数目的凹槽。
在尤其由IGBT的阴极形成的大面积第1主接线端(作为金属化层示出)和栅接线端4以及栅极框8之间安排绝缘体7。根据本发明,栅接线端4或栅极框8与IGBT的栅极5的多晶硅层直接连接,即没用栅指的中间连接。这在图4中用剖面示出。IGBT的多晶硅层5直接与栅接线端4相连。其余的IGBT单元2的多晶硅层5在组件内并联。图5描绘了多晶硅层5排列的实施例。在这种情况下它大面积复盖芯片并且具有凹槽5’。在图4也可以清楚地看到安排在栅接线端4和主接线端3之间的绝缘体7或为此用的沟。
显然栅接线端4也可以安排在IGBT芯片1的中央。图3示出该实施例。栅接线端4仍是被绝缘体7包围,该绝缘体7使栅接线端4与主接线端3断开。
