As a former OEM employee working in sales and field ops, I'd been entrenched in FABs for over 20 years.  I know the engineers, org charts, decision makers, installed bases, and general 'care-abouts' of my Texas based customers.  My network continues to grow and now exceeds some 2400 industry contacts.

Texas Instruments is the dominant player here with multiple manufacturing facilities. TI has extraordinary buying power and they continue to grow, invest, and dominate the sectors where they compete.

Samsung is the other powerhouse.  They've been the world's leader in capital spending, surpassing mighty Intel.  Samsung demands local and frequent supplier support.

Freescale, Maxim, Spansion, Finisar, DRS, Raytheon, Honeywell, SVTC, XFAB and a host of others offer excellent buying potential.
