Why is Build up IC Substrates?

The semiconductor industry is evolving at a fast pace towards smaller process nodes and more heterogeneous integration, which greatly challenges the capabilities of established packaging methodologies. Chips are operating at higher input and output densities and higher electrical performance with improved thermal management. This turnaround trend allows build up IC substrates become increasingly important in the high-end electronics of today. Through sequential layering and advanced dielectric materials, these special carriers enable ultra-fine routing and provide the microvia structures required to support future technology nodes.

The Core Concept of build up IC substrates

Standard printed circuit board production involves significant mechanical drilling and use of thick core materials, whereas build up IC substrates manufacture is much closer to adhesion of thin dielectric films and copper layers that are sequentially added. This advanced technique enables the production of laser-drilled blind and buried microvias. What you get is a highly complex, yet extremely compact interconnection network that can bridge the microscopic scale of silicon die pads to the macroscopic scale of the main system board. These high-performance substrates are vital in complex package configurations such as flip chip ball grid arrays, system in package modules, and chiplet architectures. They are extensively used in space and performance constrained applications such as high-performance computing, AI processors, automotive electronics, and mobile communications.

Major Design Aspects for build up IC substrates

In order to design build up IC substrates, one should have a thorough knowledge of electrical, thermal, as well as mechanical performance. Engineers must consider the chip bump pitch then choose a routing strategy for priority escape. With increasing density of die pads, designers use staggered or stacked microvia structures to transport signals on multiple layers efficiently without consuming too much area. Design engineers have to focus on the Power integrity and Signal integrity. High speed transmission requires precise impedance control, low signal crosstalk, and solid reference planes for preventing loss of data. On the other hand, power delivery networks should also have low inductance to maintain a stable voltage for a high-current processor. And the thermal expansion mismatch between them is also a critical focus of design. In addition, build up IC substrates are made of different materials such as copper and organic resins, asymmetric pattern or unbalanced copper lay out will cause intense warpage phenomenon. Too much warp can reduce assembly yield in flip chip attach process and lead to reliability failures at a later stage.

The process of building up IC substrates

Building up build up IC substrates is a very precise and controlled process. Typically, it starts with a rigid core, however for ultrathin application, coreless versions are also very much in demand. A high end build-up film is laminated by manufacturers to the base, followed by precision laser drilling to create microvias. Subsequently, a desmear process cleans via holes, and electroless and electrolytic copper plating fills the vias and build the conductive layers. To create ultra-fine lines and spaces, producers employ the semi-additive or modified semi-additive process. Sophisticated photolithography and etch processes allow intricate copper patterns to be defined. This is repeated for every additional layer until desired routing density is achieved. In the final step, solder mask application and surface finishing are carried out to make the substrate suitable for chip assembly. Heavy quality control was a must. AOI, cross-section analysis, and electrical testing confirm that each and every microvia is perfectly formed, no voids, no cracks.

Substrate-like PCB is now a key interconnect technology for  small, high performance electronics in 2026. In 2026, substrates like pcb market is being fueled by demand for smartphones, AI  edge devices, automotive electronics, industrial control systems, smart modules and advanced chip packages. SLP fills the gap between traditional HDI PCB and IC substrate technology with finer traces, smaller microvias, thinner dielectric layers and higher routing density. The substrate-like PCB market is not all just  flagship smartphones. It is more and more relevant in AI hardware, high-speed-computing modules, smart cars, medical electronics, and small-scale industrial applications. With progressively more powerful semiconductor chips and ever-increasing package density, system boards must accommodate faster signals, denser routing, lower power dissipation, and enhanced thermal performance. For this reason, SLP is evolving from a premium option to a strategic manufacturing platform. 

Technology of Substrate-like PCB Manufacturing

SLP ― production of PCBous, Substrate-like PCB), but requires much higher accuracy than traditional multilayer PCB production. The biggest process is mSAP, or modified semi-additive process. Traditional subtractive etching removes a layer of copper from the entire copper layer, however, it is hard to keep the trace accuracy when the line and space decreased under typical HDI capacity. mSAP can generate tighter copper traces and minimize side etching to achieve fine lines as low as 30 microns or less, subject to the capability of supplier and product design. The challenging in manufacturing for the substrate-like PCB market is not only how to make fine line, but also how to make fine line obtaining stable yield. SLP boards typically employ laser microvias, stacked vias, staggered vias, copper-filled vias, sequential lamination, and thin dielectric layers. These layers enable designers to route processors, memory, RF circuits, high-speed interfaces, sensors, and power management circuits in a tiny footprint. Mechanical drilling cannot achieve the microvia size and registration accuracy required by advanced SLP designs, thus laser drilling is a necessity (Love Getting This job Done). Laser direct imaging is also frequently employed to enhance the precision of patterns. Vacuum lamination, horizontal copper plating, plasma etching, auto optical inspection, X-ray inspection, impedance testing and microsectioning are all included in the process control system. Materials are also a key consideration when it comes to substrate-like PCB as the market requires high performance copper clad laminate, ultra-thin copper foil, resin coated copper, low-profile copper, low-loss dielectric materials as well as high-Tg resin systems. These materials must be capable of maintaining dimensional stability through multiple lamination cycles and result in good copper adhesion after laser drilling, electroplating. Dielectric loss and impedance stability are critical for high speed applications(e.g: PCIe, USB, MIPI, HDMI, Ethernet, DDR memory routing).

Market Situation With Data Support

The substrate-like pcb market is aided by the overall electronics and semiconductor industry recovery and upgrading. The global PCB market grew in 2024 after the slump in 2023 to approximately the low 70 billion US dollar level according to Prismark and is anticipated to foster through the latter half of the decade. The sales of the high-end PCB or sub-segment, to which HDI, IC substrate, server boards, automotive boards and advanced MLOP (multilayer OP) boards belong, will increase at a higher rate than the goods of the normal PCBs. SLP growth outlook is substantiated by semiconductor data as well. The World Semiconductor Trade Statistics (WSTS) said that the global semiconductor market was about 627 billion US dollars in 2024 driven by AI, memory recovery, automotive electronics and industrial demand. WSTS further predicted that the growth would continue in 2025 and 2026, pushing the market over the 700 billion US dollar mark. In the case of substrate-like PCB market, the expansion in the semiconductor directly leads to the demand increase for high-density board, advanced module, and chip package related interconnect products. Advanced packaging remains a key enabler. Yole Intelligence projects a very robust long-term growth for advanced packaging revenue driven by AI processors, chiplets, high-bandwidth memory, high-performance computing, and automotive processors. The substrate-like PCB segment is able to capitalise on that trend as substrate-like PCBs and chip package substrates have similar fine-line requirements, high-precision materials, strict process control and stable electrical performance.

Capacity Pressures From Materials to Chip Package

The T2 supply demand crunch of 2026 is simple: it spans every stage of production. Pressure starts with the materials. Henkel has products for a long qualification cycle for ultra-thin copper foil, low-loss laminate, specialty resin, precision dry film, advanced plating chemicals and high-end solder mask materials. A material switch might influence impendance, warpage, copper removal, via reliability, thermal cycling, and products long life. With the automotive, medical, industrial, and communication customers, the materials aren’t replaceable without full validation. Equipment is a bottleneck, too . The SLP production requires use of laser drilling machines, laser direct imaging systems, vacuum presses, cleanroom production facilities, horizontal plating lines, high-resolution inspection systems, and reliability testing machines. These machines are expensive and time consuming to install. Even when new equipment is up and running, producers must spend months tuning the process and increasing yield. Engineering talent limits the substrate-like PCB market as well. Fine-line manufacturing needs skilled CAM engineers, process engineers, plating experts, material specialists and quality teams. Yield control is difficult if you are doing products with thin boards, with high layer counts, with fine-pitch components, with stacked microvias, and with tight impedance requirements. Chip package capacity adds another layer of pressure. AI chips, networks processors, automotive processors, and high-end memory packages are taking up more ABF substrate, advanced package substrate, and assembly space. Top tier semiconductor manufacturers have expanded advanced packaging capacity further, but yet public industry commentary continues to indicate tight demand for chip package driven by AI. This results in the substrate-like PCB market being highly correlated with IC substrate and advanced packaging supply chains. # Features of HQICSUBSTRATE Company HQICSUBSTRATE As a leading supplier in traditional substrate like PCB, HQICSUBSTRATE caters to the substrate like pc board market including hdi, SLP manufacturing support, IC substrate related engineering and one advanced circuit board solutions that meets the demand of high density interconnect technology.
