Abstract

公开了一种用于防止绝缘破裂的虚设图形的形成方法,通过在靠近监测部分或外围电路区的选定部位上,形成宽度和高度恒定的虚设图形,可以防止绝缘层的破裂。

Description

防止绝缘层破裂的虚 设图形的形成方法
本发明涉及形成虚设图形的方法,防止绝缘层破裂,更具体地说,涉及在监测部分的周边部分和/或外围电路区域上,形成宽度和高度恒定的虚设图形的方法,防止绝缘层的破裂,其起因在于,当在划痕线上形成监测部分用来监测接触孔的蚀刻深度时,因连续热处理而使监测部分棱角处破裂。
在半导体器件的制造中,在划痕线上设置监测部分,用来监测接触孔的蚀刻深度,接触孔形成在绝缘层上,用于连接导电线。如图1所示,监测部分4设置在划痕线3上,由划痕线3分成多个单元区1。每个单元区1由隔离环2限定,单元区1的周边部位成为外围电路区域1A.
当在图1的状态下进行热处理时,由于在监测部分4的棱角处发生破裂,结果导致破裂穿过外围电路部位1A形成在单元区1。破裂是由应力引起的,应力是由于密集在监测部分棱角处的单一或多种材料的绝缘层膨胀时产生的。所以,制造半导体器件的处理难于进行,从而降低了半导体器件的产率。
因此,本发明的目的是提供一种形成虚设图形的方法,该虚设图形形成在监测盒部分的周边部位和/或外围电路区域中未形成图形部分的选定部位上,以使破裂不扩展至单元区,防止绝缘层破裂。
为达到上述目的,根据本发明的形成虚设图形的方法包括以下步骤:
提供晶片,其上由划痕线和隔离环限定出单元区和外围电路区域;在设置监测部分之前,在邻接监测部分的选定部位和外围电路区域上形成虚设图形。
为了更清楚了解本发明的特征和目的,以下结合附图做详细说明。
图1是其上形成有监测部分的晶片。
图2是其上的监测部分已出现破裂的晶片。
图3是根据本发明其上形成有虚设图形的晶片。
在几幅图中,相同的参考标号代表相同的部分。
图3所示晶片,根据本发明已在其上形成有虚设图形,用于防止绝缘层的破裂。在划痕线3的监测部分10的周边部位上形成有虚设图形10。在未形成图形的单元区1的外围电路部位上也形成有虚设图形20。这些虚设图形10和20必须在设置监测部分之前形成。亦即,利用形成绝缘层的掩模或者形成导电线的掩模,以靠近形成虚设图形的掩模的选定部位,来形成虚设图形10。因此,可以用多晶硅或绝缘层来形成虚设图形10和20。必须较厚地形成虚设图形10,并且宽度和高度恒定,例如宽2-3μm,高0.3-0.7μm。而且,虚设图形10与监测部分4之间的距离应为4-7μm。
在外围电路区1A的选定部位上形成虚设图形20时,设计形成导电线的掩模时必须考虑相邻导电线之间的绝缘,因为在单元区内要设置大量的导电线。蚀刻绝缘层的掩模必须设计成与靠近监测部分4的隔离环2相连。如果可能的话,应较厚地形成虚设图形20,具有恒定高度,例如,图形宽2-3μm,高0.3-0.7μm。隔离环2与虚设图形2之间的距离应为8-12μm。
根据本发明,在导电线或绝缘层的布图工艺中,形成靠近监测部分4的虚设图形10和靠近外围电路区1A的虚设图形20。虚设图形10和20可同时形成,也可形成虚设图形10和20中的任一个。
如上所述,热处理所引起的应力被虚设图形减弱,从而防止了绝缘层的破裂。
尽管是在优选实施例中以一定程度的特定性对本发明做了说明,但是本领域的技术人员知道,这里公开的优选实施例仅仅起到例子的作用,在不脱离本发明的精神和范围的条件下,可以改变其各部分的结构、组合及布置。
