Description

多射极型双极结晶体管、双极CMOS DMOS器件及其制造方法
技术领域
本发明涉及一种多射极型双极结晶体管(poly-emitter type bipolarjunction transistor)、BCD(双极CMOS DMOS)器件、多射极型双极结晶体管的制造方法、及BCD器件的制造方法。
背景技术
通过使用BCD工艺,可以将双极器件、CMOS(互补金属氧化物半导体)和DMOS(双扩散MOS)形成在单一晶片中。除了双极器件、CMOS和DMOS之外,逻辑电路、PMOS、NMOS、电阻器、电容器和二极管也能通过BCD工艺集成在单一芯片中。例如,在通过BCD工艺制造CMOS和DMOS时,能够制造双极晶体管。
双极晶体管具有应用结发射极(iunction emitter)的结构。因此,在通过现有的BCD工艺制造双极晶体管的情况中,改善高频特性、增加放大增益和击穿电压、以及扩大可操作范围受到限制。
发明内容
实施例涉及一种多射极型双极结晶体管、BCD(双极CMOS DMOS)器件、多射极型双极结晶体管的制造方法、及BCD器件的制造方法。实施例涉及一种使用BCD工艺的多射极型双极结晶体管及多射极型双极结晶体管的制造方法,使用BCD工艺的BCD器件及BCD器件的制造方法。
根据实施例的多射极型双极晶体管可以包括:掩埋层,形成在半导体衬底的上部上方;外延层,形成在半导体衬底上方;集电极区,形成在外延层上并连接到掩埋层;基极区,形成在外延层的上部上方;以及多射极区,形成在半导体衬底的表面上方的基极区中并且包括多晶硅材料。
根据实施例的BCD器件可以包括:多射极型双极晶体管,具有包括多晶硅材料的多射极区;以及CMOS和DMOS中的至少一个,与多射极型双极晶体管一起形成在单一晶片上。
根据实施例用于形成多射极型双极晶体管的方法可以包括如下步骤:在半导体衬底的上部上方形成掩埋层;在半导体衬底上形成外延层,并且在外延层上形成连接到掩埋层的集电极区;形成限定出基极区和射极区的隔离层;在隔离层下方的衬底区上形成基极区;在基极区的上部的一部分上形成基电极;以及在通过隔离层与基电极间隔开的基极区的上部的一部分上形成包括多晶硅材料的多射极区。

附图说明
示例性图1是显示根据实施例的包括多射极型双极晶体管的BCD器件的侧剖视图。
示例性图2~图7是根据实施例的多射极型双极晶体管的制造过程的剖视图。
具体实施方式
以下将参考附图详细描述多射极型双极晶体管、BCD器件、用于制造多射极型双极晶体管的方法、及用于制造BCD器件的方法。
示例性图1是显示根据实施例的包括多射极型双极晶体管的BCD器件的侧剖视图。通过BCD工艺制造根据实施例的BCD器件。在示例性图1中,区域“A”是双极晶体管区域,区域“B”是CMOS区域,并且区域“C”是DMOS区域。
除了多射极型双极晶体管之外,尽管示例性图1中未示出,根据用于制造实施例的BCD的方法,可以将逻辑电路、PMOS、NMOS、高压MOS、中压MOS、低压MOS、DEMOS(漏极扩展MOS)、LDMOS(侧向双扩散MOS)、电阻器、电容器及二极管集成在单一芯片中。
参照示例性图1,多射极型双极晶体管包括掩埋层110、外延层120、集电极区130、基极区140、基电极160、隔离层150及多射极区170,它们形成在衬底100上的双极晶体管区域A中。
CMOS包括在CMOS区域B中的PMOS和NMOS。通过隔离层150a,PMOS与NMOS隔离。PMOS和NMOS中的每个均可包括掩埋层110a、重掺杂N-型阱205、P-型阱200、N-型阱210、栅极215和225以及源极/漏极区220和230。栅极215和225还可以包括栅极绝缘层和间隔件(spacer)。
DMOS可以包括掩埋层110b、重掺杂N-型阱300、P-型体(P-type body)305、用于隔离各个区的隔离层150b、栅极320、形成在P-型体305上的P-型离子注入区310以及第一N-型离子注入区315、以及在DMOS区域C中在栅极320的另一侧上形成的第二N-型离子注入区325。形成在栅极320与第二N-型离子注入区325之间的隔离层150b能够加长P-型体305与第二N-型离子注入区325之间的电流通路,从而DMOS可以作为高压器件。
以下将参考示例性图1~图7详细描述根据实施例的包括多射极型双极晶体管的BCD器件的制造方法。在实施例中,多射极型双极晶体管可以与BCD器件同时制造,因此以下的描述将集中于在双极晶体管区域A中形成的多射极型双极晶体管。以下描述的每个工艺可以是单一工艺或复杂工艺,所述工艺用于制造包括以下各项的组中的一个或至少两个:多射极型双极晶体管、逻辑电路、PMOS、NMOS、高压MOS、中压MOS、低压MOS、DEMOS、LDMOS、电阻器、电容器及二极管。
示例性图2~图7是根据实施例的多射极型双极晶体管的制造过程的剖视图。首先,晶片状半导体衬底100,例如,单晶硅衬底可以被切割至预定厚度。半导体衬底100的表面可以被抛光,以便可以在衬底上形成外延层120。
然后,如示例性图2所示,可将N型掺杂剂注入到半导体衬底100的上部的一部分中,以形成N+型掩埋层110。然后,通过热处理工艺扩散离子注入区。此时,也可以在衬底100的CMOS区域B和DMOS区域C中分别形成掩埋层110a和110b。在形成N+型掩埋层110之后,如示例性图3所示,通过对半导体衬底100执行外延生长工艺,可以形成外延层120。
在形成外延层120之后,如示例性图4所示,可以在外延层120上形成连接到N+型掩埋层110的N+型扩散区130。该N+型扩散区130可以作为集电极区。此时,可以同时形成重掺杂N-型阱205和300。
然后,可以形成隔离层150。如示例性图5所示,隔离层140限定出基极区与射极区,同时将基极区与射极区隔离。此时,可以同时在CMOS区域B中和DMOS区域C中形成隔离层150a和150b。然后,可以执行离子注入掩模工艺和离子注入工艺,以在CMOS区域B中形成P-型阱200和N-型阱210以及在DMOS区域C中形成P-型体305。
如示例性图6所示,可以注入P-型掺杂剂以形成作为基极区的P-型漂移区140。在形成基极区140之后,如示例性图7所示,可以形成基电极160。然后,可以对包括CMOS、DMOS、低压NMOS及低压PMOS的有源区执行注入工艺,由此调节阈值电压。
之后,执行用于形成CMOS和DMOS的栅极215、225及320的工艺。此时,还可以形成根据实施例的多射极型双极晶体管的多射极170。
然后,可以在衬底100的整个表面上方形成绝缘层。该绝缘层可以被图案化,以使栅极绝缘层形成在CMOS区域B和DMOS区域C中。此时,完全移除双极晶体管区域A的绝缘层。
之后,可以在衬底的整个表面上涂覆多晶硅层。可以在该多晶硅层上形成光致抗蚀剂图案。该光致抗蚀剂图案限定出CMOS、DMOS的栅极215、225与320,以及双极晶体管的射极区。然后,通过使用光致抗蚀剂图案作为蚀刻掩模来蚀刻多晶硅层,由此形成栅极215、225与320以及多射极170。
可以通过上述工艺获得示例性图1中的区域A中显示的多射极型双极晶体管。然后,可以在每个MOS区中形成N-型LDD(轻掺杂漏极)区和P-型LDD区。可以在栅极215、225及320的两侧形成侧壁和间隔件。
在形成间隔件之后,可以在CMOS区域B中形成源极/漏极区220和230。可以在DMOS区域C中形成P-型离子注入区310、第一N-型离子注入区315和第二N-型离子注入区325。
然后,可以在多射极170、基电极160、栅极215,225及320、源极/漏极区220和230、以及离子注入区310,315及325中至少之一上形成硅化物。此外,还可以执行用于形成具有多层结构的绝缘层、接触插塞、金属互连及保护层的工艺。
可以通过上述工艺获得根据实施例的包括多射极型双极晶体管的BCD器件。根据实施例,通过BCD工艺可以在单一芯片中将多射极型双极晶体管与BCD器件一体地(integrally)形成。因此,可以获得具有较高频率特性、高放大增益和击穿电压及较宽可操作范围的双极晶体管。
对本领域普通技术人员来说,对公开的实施例的各种修改和变化是显而易见的。因此,公开的实施例覆盖了显而易见的修改和变化,其包括在随附的权利要求书及其等同范围中。
