There are several methods for 3D IC design, including recrystallization and wafer bonding methods. There are two major types of wafer bonding, Cu-Cu connections (copper-to-copper connections between stacked ICs, used in TSVs) [18] [19] and through-silicon via (TSV). 3D ICs with TSVs may use solder microbumps, small solder balls as an interface between two individual dies in a 3D IC.

Recently, complementary–metal–oxide semiconductor (CMOS)-compatible 150-nm-diameter interconnects with a single CNT–contact hole resistance of 2.8 kOhm were demonstrated on full 200 mm-diameter wafers. Also, as a replacement for solder bumps, CNTs can function both as electrical leads and heat dissipaters for use in high-power amplifiers.
Additive manufacturing, or "3D printing," is commonly used for prototyping, as the machines can create parts without the expensive tooling process or the need for skilled machining.
The car consists of 50 individual parts, far less than a traditional vehicle (which is manufactured with roughly 30,000 parts). [36] The Strati was designed by Michele Anoè, [ 37 ] a member of the Local Motors community, and is produced in small quantities to serve strategic partnerships, such as with NXP Semiconductors .

Texans general manager Nick Caserio didn't hide how he really felt about the NFL's decision to suspend Azeez Al-Shaair for his hit on Trevor Lawrence.
The automotive aftermarket is the secondary parts market of the automotive industry, concerned with the manufacturing, remanufacturing, distribution, retailing, and installation of all vehicle parts, chemicals, equipment, and accessories, after the sale of the automobile by the original equipment manufacturer (OEM) to the consumer.
