The semiconductor-equipment industry didn't do too well last year, and compared to the semiconductor industry, it hasn't done too well since 2000.

In the chart below, the semiconductor industry, represented by the line, has diverged from the equipment industry since the downturn of 2001. The solid trendlines are telling.

Depending on whom you talk to, the semiconductor-equipment industry dropped between 40% and 50% in 2009. The top 10 chip-equipment companies are listed in the table below along with their change in revenue between 2008 and 2009.

The revenues are shown in dollars, and the change in revenue is somewhat deceiving because currency exchange rates are a factor.

It's no secret in the semiconductor-equipment industry that

Applied Materials

(AMAT) - Get Report

and

Novellus

(NVLS)

don't have a warm, fuzzy feeling about each other. Back in 2004, a patent-infringement lawsuit was settled that ended seven years of litigation between the two companies. Problems actually started in 1984 when Novellus was founded by ex-Applied Materials employees.

In reality, Applied and Novellus only compete against each other in a handful of sectors. Overall, from the chart below, Novellus' revenue dropped 37.4% while Applied's dropped 38%. Essentially the difference is in the noise level when you factor in, or more precisely take out, revenue components such as service and spare parts.

What about individual sectors? We give the edge in the largest sector, PVD (physical vapor deposition), to Novellus, but only marginally as revenue decreased 37% vs. 41% for Applied.

Comparing the two companies, Novellus increased market share in 2009 in four of the six categories.
