Samsung, the world chief in semiconductor house, has announced that it has developed a brand new chip packing know-how that would make chips sooner and extra power-efficient. The I-Cube4 know-how is an enchancment over the corporate’s I-Dice 2 know-how from 2018 and X-Cube technology from 2020.
The corporate’s I-Cube4 (Interposer-Cube4) is a 2.5D heterogeneous chip packaging know-how. It may be used to horizontally place a number of logic dies (CPU, GPU, and NPU) and a number of other HBM (High Bandwidth Memory) dies on high of a silicon interposer, making a number of dies act as a single chip. This know-how was developed in March 2021, and it has already been used to place one logic die, and 4 HBM dies on a single chip.
Samsung says that chips made utilizing i-Cube4 know-how can be utilized in high-performance purposes similar to 5G, AI, cloud, and enormous knowledge facilities. This know-how allows even sooner communication between the reminiscence and logic models of a chip.
Because the silicon interposer within the I-Cube4 is thinner than paper, there’s a chance of bending and warping, negatively affecting the product high quality. Nonetheless, Samsung Foundry has fastidiously studied easy methods to management interposer warpage and thermal enlargement by altering the fabric and thickness, eradicating the issues. It has additionally developed its personal mold-free construction to dissipate warmth effectively.
The corporate has additionally enhanced the yield by conducting a pre-screening take a look at to establish faulty merchandise throughout fabrication. This course of removes extreme steps within the course of, saves prices, and improves turnaround instances. Samsung can also be creating even higher know-how referred to as I-Cube6 through the use of superior course of nodes, superior 2.5D and 3D packaging, and high-speed interface tech.
Moonsoo Kang, Senior Vice President of Foundry Market Technique at Samsung Electronics, stated, “With the explosion of high-performance purposes, it’s important to offer a complete foundry resolution with heterogeneous integration know-how to enhance the general efficiency and energy effectivity of chips. With the mass-production expertise amassed by I-Cube2 and the business breakthroughs of I-Cube4, Samsung will wholly assist prospects’ product implementations.”
