You should expect this trend to continue. Semiconductors have become a hideously expensive business, aggravated by fewer fabs and more draconian fab/IP acquisition costs. It's a well known that nobody on Sand Hill road will touch semiconductor startups at all, leading to a stagnant collection of semiconductor companies founded 20+ years ago. There was recently announced a semi-only incubator here in SV[1] because nobody can raise any traditional VC money, although time will tell how many successful exits it will have.
