Table 8: Company Developments and Commercial Implications
| Evidence | Commercial effect | Buyer action |
|---|---|---|
| On 23 September 2026, LPKF announced a letter of intent for NEXAR LIDE systems from a leading Asian advanced packaging manufacturer [1]. | Shows via-making equipment moving toward a first glass substrate production facility. | Ask suppliers which via process is qualified at production speeds and on what panel size. |
| On 26 March 2026, LPKF said its 2026 outlook excludes potential high-volume advanced packaging orders [3]. | Volume adoption depends on qualification of downstream steps and has not yet arrived. | Plan early supply as sample and low-volume lots from more than one source. |
| The Glass Panel Technology Group, led by Fraunhofer IZM with 15 companies, held its kick-off in Berlin on 1 October 2025 [4]. | Shared reliability testing may reduce qualification cost for panel-based glass. | Compare supplier data against thermal cycling, moisture sensitivity and vibration tests. |
| On 6 November 2026, RENA published a note on its ISMP 2026 talk on tuning through-glass-via shapes by etching [17]. | Via shape control is a live process-engineering topic for glass-core packaging. | Specify via taper and aspect ratio in purchase documents. |

How are the companies positioned?
A company's position depends on where it sits between raw glass and a finished, via-filled part. AGC and SCHOTT supply the glass in wafer and panel form [9][11]. PLANOPTIK, Tecnisco and 3DGS process glass into vias, metallised wafers and interposer designs [13][15][18]. LPKF and RENA supply the laser and etching steps that form vias [16][1].
What matters when a buyer qualifies a glass interposer supplier?
Format, glass type and via geometry come first. AGC lists wafers of 150 mm to 300 mm and panels of 510 x 515 mm [11], Tecnisco lists vias of 0.05 to 0.3 mm [15], and RENA lists taper angles down to 1 degree [16]. Reliability evidence matters as much, since the Glass Panel Technology Group plans thermal cycling, moisture sensitivity and vibration testing [4].
Which capabilities distinguish the product offers?
Via formation without cracks, thickness control and metallisation are the clearest differences. LPKF cites zero micro-cracks and zero chipping with LIDE [6], SCHOTT cites total thickness variation as low as 0.5 micrometres [9], and PLANOPTIK offers metallisation, cavities, redistribution layers and solder mask [13].
How does geographic reach affect competition?
Suppliers sell across regions, so buyers need to check where the glass is processed. 3DGS lists an Albuquerque address [18]. LPKF is headquartered in Garbsen, Germany [1]. The Asian customer in LPKF's September 2026 letter of intent is preparing a production facility [1]. Confirm the processing site and qualification lead time before each order.
