Samsung Electro-Mechanics Glass Substrate Mass Production Target Delayed Beyond 2028

Reliability testing bottlenecks for glass substrate prototypes force Samsung Electro-Mechanics to postpone GlaSSEM construction and equipment orders, pushing mass production targets further into uncertainty.

Woofun AI reports that Samsung Electro-Mechanics has delayed its semiconductor glass substrate investment plans due to reliability testing failures by global communication clients. The construction schedule for GlaSSEM, the joint venture with Toyo Fine Chem, is postponed, leaving equipment ordering timelines uncertain after multiple deadline extensions since last year.

Prototypes are being remade at the Sejong plant, causing further delays to the original investment plan. Although mass production equipment for deposition, etching, laser drilling, and testing has been selected, the target date has shifted from the second half of 2027 to 2028, with expectations of additional postponements.
