SAP Process

Introduction

Semi-Added Process abbreviated as SAP, using on the build-up-layer pattern forming as follow:First depositing with a very thin copper seed on build-up film and in micro vias as a conductive layer; Laminating photosensitive dry film resist on the surface; forming the circuits pattern on the dry film using graphic transfer technology(exposure and development); and then metalizing with copper by filling the spaces of dry film pattern; Removing copper seeds between metalizing copper patterns by flash-etching and forming the copper circuits finally.

Compared with other conventional process, SAP Process needs higher level technology control. The process is as follows

SAP、MSAP and Tenting are three kinds of mainly processes in PCB industry, and each has its own advantages and disadvantages. And the processes are constantly evolving and advancing. In a lot of different applications, the boundaries between the processes are blurred, and could be used in combination sometimes.QHIC has SAP、MSAP and Tenting process with well-rounded technology, and can provide high-quality low-cost solutions according to customers’ needs.

 

Application Areas

IDM Customization Service

From advanced processes to specialty processes, we use our IDM vertical integration experience to help customers overcome design-process collaboration challenges.

01

Supports advanced nodes such as [5-22nm FinFET/BCD/GAA] to meet the needs of high-performance computing (HPC), AI chips, etc.

02

MPW (Multi-Project Wafer) Service: Small batch trial production to reduce customers' initial costs. Customized process development: Cooperate with customers to conduct DTCO (Design-Process Co-Optimization), customize design rules and process parameters.

03

We support the joint solution of "wafer foundry + advanced packaging" (such as 3D IC, heterogeneous integration) to avoid the loss of multi-supplier collaboration. Unlike pure foundries, we verify the process stability through mass production of our own chips to reduce the risk of tape-out for you.
