Through Silicon Via (TSV) has become a key technology for advanced packaging applications for various products such as CMOS image sensors, 2.5DICs, 3DICs and plasma dicing. The Primo TSV® tool is AMEC’s first high-density plasma TSV etch product for high-performance TSV applications. The system employs a cluster configuration design which allows for up to three dual-station process modules to be attached to the main frame. Each module can process two wafers simultaneously. AMEC offers 200mm and 300mm TSV production tools capable of etching holes with CDs ranging from hundreds of microns down to <1um, and depth of up to several hundred microns. In addition, with its strong process-tuning capabilities, the tool can generate diverse profiles based on customer requirements (i.e., vertical, cone-shaped, tapered, and more). Finally, with unique features, such as a pre-heating station, wafer-edge protection ring, and low-frequency RF pulsing bias and side gas feed, the Primo TSV is an ideal tool to deliver the technology, flexibility, and productivity needed for the TSV market.

iDEA stands for “integrated Dual-station Etch and Asher”. It represents a new concept developed by AMEC that integrates one or two dual-station D-RIE or AD-RIE process modules with a DsA (“Downstream Asher”) chamber on the same platform. AMEC’s DsA design is a dual-station chamber that utilizes a top-mounted remote plasma source (“RPS”) to create reactive species that are then uniformly delivered to the wafer surface for photo-resist removal. This approach not only effectively removes the photo-resist material, but also offers less direct plasma exposure to the wafer. This is important for customers running devices that are highly sensitive to surface charge build-up and potentially risk of plasma-induced damage (PID). Avoiding PID can involve exhaustive and expensive efforts to modify integration schemes or add dedicated machines for steps such as photo-resist removal. The fully integrated Primo iDEA® system offers a cost-effective solution to perform etch processing and dedicated photo-resist removal within the same platform.

The Primo Twin-Star® system is AMEC’s advanced 300mm etch product based on Inductively Coupled Plasma (ICP) technology. It is a cluster tool that can be conﬁgured with up to three dual-station chambers and two optional on-board integrated strip chambers. Each dual-station chamber can process one or two wafers at the same time with highly uniform and identical results. The ICP coils employ AMEC’s proprietary low capacitive coupling 3D coil design which enables more independent ion density and ion energy control. The electrostatic chuck has multi-zones with independent and dynamic temperature settings which enhances CD control. The chamber interior is coated with high-density plasma-resistant material for more robust process repeatability and more steady productivity. The product is intended for etching Si with various CD and depths in CIS and power device, and thin conductive/dielectric ﬁlms for various logic and DRAM IC devices. It has signiﬁcant cost advantages compared to single-station chamber product.
