摘要:
The invention provides a lateral double-diffused metal oxide semiconductor (LDMOS). The pre-metal dielectric layer (PMD) of the LDMOS is a silicon rich content material. Additionally, the inter-layer dielectric layer (ILD), inter-metal dielectric layer (IMD), or protective layer of the LDMOS may be formed of a silicon rich content material.
