The semiconductor packaging method comprises the following steps: mounting at least one bare chip to be packaged on a carrier plate, wherein the surface of the bare chip close to the carrier plate is a front surface, and a plurality of welding pads are arranged on the front surface of the bare chip; forming a first encapsulating layer, wherein the first encapsulating layer covers the carrier plate and encapsulates the at least one bare chip to be encapsulated; stripping the carrier plate to expose the front surface of the bare chip; fixing at least one lead frame on the front surface of the bare chip, and electrically connecting the pins of the lead frame with the welding pads of the corresponding bare chip; the lead frame comprises at least one lead area, each lead area corresponds to one bare chip, and each lead area is provided with at least one lead; and forming a conductive structure for leading out the welding pad on the pin.)

半导体封装方法及半导体封装结构

技术领域

本申请涉及半导体技术领域,特别涉及一种半导体封装方法及半导体封装结构。

背景技术

常见的半导体封装技术,比如裸片封装技术主要包含下述工艺过程:首先将裸片正面通过胶带粘接在衬底上,进行热压塑封,将衬底剥离,然后在裸片正面形成再布线结构,并进行封装。

在形成再布线结构的过程包括溅射、甩胶、光刻、电镀、薄膜及蚀刻等步骤,工艺比较复杂,使得整个封装工艺的封装时间较长。
