- Die shrink: How Intel scaled down the 8086 processor (righto.com)
The revolutionary Intel 8086 microprocessor was introduced 42 years ago this month so I’ve been studying its die.1 I came across two 8086 dies with different sizes, which reveal details of how a die shrink works. The concept of a die shrink is that as technology improved, a manufacturer could shrink the silicon die, reducing costs and improving performance. But there’s more to it than simply scaling down the whole die. Although the internal circuitry can be directly scaled down,2 external-facing features can’t shrink as easily. For instance, the bonding pads need a minimum size so wires can be attached, and the power-distribution traces must be large enough for the current. The result is that Intel scaled the interior of the 8086 without change, but the circuitry and pads around the edge of the chip were redesigned.

Benin (/bɛˈniːn/ ben-EEN, /bɪˈniːn/ bin-EEN; French: Bénin [benɛ̃], Fon: Benɛ, Fula: Benen), officially the Republic of Benin (French: République du Bénin), and also known as Dahomey, is a country in West Africa. It is bordered by Togo to the west, Nigeria to the east, Burkina Faso to the North-west, and Niger to the North-east. The majority of its population lives on the southern coastline of the Bight of Benin, part of the Gulf of Guinea in the northernmost tropical portion of the Atlantic Ocean. The capital is Porto-Novo, and the seat of government is in Cotonou, the most populous city and economic capital. Benin covers an area of 114,763 km2 (44,310 sq mi), and its population in 2021 was estimated to be approximately 13 million. It is a small, tropical country. It is one of the least developed, with an economy heavily dependent on agriculture, and is an exporter of palm oil and cotton. Some employment and income arise from subsistence agriculture.
