MILPITAS, CA – Global fab equipment spending is expected to decline 14% ($53 billion) in 2019 but stage a recovery of 27% ($67 billion) to set a new record in 2020, according to SEMI.

Spurred by a slowdown in the memory sector, the 2019 downturn marks the end of a three-year growth run for fab equipment spending.

Over the past two years, memory accounted for an annual share of about 55% of all equipment, a proportion expected to drop to as low as 45% in 2019 but rebound to 55% in 2020. With memory representing an outsize share of total spending, any fluctuations in the memory market impacts overall equipment spending.

A review of fab equipment spending by half-year shows high inventory levels and weakening demand led to a bigger-than-expected decline in DRAM and NAND (3D NAND) in the latter part of 2018, driving down memory spending 14%. The downward trend is expected to continue into the first half of 2019, with memory spending dropping 36%, though memory spending could rebound 35% in the second half of the year.

Despite the comeback in the second half of 2019, the report points to a 30% plunge in overall memory spending for the year, after reaching record highs in 2018.

Foundry is the second largest sector after memory for fab equipment spending. Over the past two years, the annual share ranged from 25% to 30% per year. In 2019 and 2020, SEMI expects the yearly share to hold steady at about 30%.

And while foundries typically fluctuate less than the memory sector in equipment spending, they are not immune to shifts in the market, the firm says. For example, following the decline of memory, foundry equipment spending fell 13% in the second half of 2018 from the first half of the year.
