This article provides an overview of the published mechanical stress data for boron- and phosphorus-contained silicate glass films deposited by a variety of chemically vapor deposited (CVD) techniques, i.e. atmospheric and sub-atmospheric pressure (APCVD, SACVD), low pressure, plasma-enhanced (LPCVD, PECVD). The emphasis is done on borophosphosilicate glass films (BPSG) dedicated for the use in micro-electro-mechanical system (MEMS) and micro-opto-electro-mechanical system (MOEMS) technologies as a material with significantly higher film thickness as compared with its traditional use in microelectronics technology as a flow-able planarized interlayer dielectric. The article covers stress features of as-deposited and thermally annealed films with the boron and phosphorus concentration range in between about 1–12 wt%. Phosphorus is detected as a main film component responsible for stress type (tensile or compressive) and its particular values. Film deposition techniques strongly a...

评论—化学气相沉积含硼和磷的硅酸盐玻璃薄膜中的机械应力:综述

本文概述了通过各种化学气相沉积(CVD)技术沉积的含硼和磷的硅酸盐玻璃薄膜的机械应力数据,该技术包括大气压和低于大气压(APCVD,SACVD),等离子增强(LPCVD,PECVD)。重点放在专用于微机电系统(MEMS)和微光电机电系统(MOEMS)技术的硼磷硅玻璃膜(BPSG)上,该膜的膜厚比其膜厚高得多。在微电子技术中的传统用途是作为可流动的平面化夹层电介质。本文介绍了沉积态和热退火薄膜的应力特征,硼和磷的浓度范围在1-12 wt%之间。磷是引起应力类型(拉伸或压缩)及其特定值的主要薄膜成分。薄膜沉积技术强烈地...
