Deconstructing PLP Warpage: Low-Temp PSPI, Balance Films, and Supplier Analysis

Description

For the current year of 2026, TSMC plans to establish a trial production line CoPoS through its subsidiary, VisEra, with trial production scheduled for 2027. Consequently, this year will be a critical window for product validation and deliveries for related equipment and material providers. To address the warpage issues inherent in large-area panel-level packaging (PLP), specialty chemical suppliers such as AMC, WaferChem, and Everlight Chemical showcased corresponding solutions at Touch Taiwan 2026, drawing significant market attention.

Accordingly, this report provides an in-depth analysis of: (1) the background of the material technology PLP and its market outlook; (2) the causes of warpage and potential solutions; and (3) warpage-suppressing materials and key suppliers. The objective is to clarify the demand drivers for PLP, the mechanisms behind panel warpage, viable countermeasures, and the emerging business opportunities for Taiwan-based companies.
